Hi everyone, We're migrating our iOS app from Auth0 custom scheme callbacks to HTTPS Universal URLs using ASWebAuthenticationSession. We've configured everything correctly, but webcredentials only works when using ?mode=developer suffix in our entitlements, which is not allowed for App Store submissions. The Issue Without ?mode=developer: Error Domain=com.apple.AuthenticationServices.WebAuthenticationSession Code=1 "Application with identifier com.example.myapp is not associated with domain auth.example.com. Using HTTPS callbacks requires Associated Domains using the webcredentials service type for auth.example.com." With ?mode=developer: webcredentials:auth.example.com?mode=developer Works perfectly! Questions Why does it work with ?mode=developer but not without it, even though Apple's CDN has the correct AASA? Is there a way to force iOS to re-verify associated domains without requiring users to delete and reinstall? How will this affect existing users who update the app? Will they need to reinstall? Is there a known propagation delay beyond the CDN showing correct data? Any guidance would be greatly appreciated. We cannot ship to the App Store with ?mode=developer, but without it, the authentication fails. Thank you!

All our workflows started to fail today due to timeouts - the notarization process is unable to finish in under 1 hour. The latest submission ID that failed after 45mins: 7449abcb-0d24-441b-a992-d5c7e7d279e3 It has never been a problem for us for the past years - is there something off on Apple side?

M4 Mac Mini: Xcode generates private keys with wrong label - codesigning impossible Background This is a follow up to my November 2024 thread "Keychain issues after installing backup on new Mac" which was closed because I had a temporary workaround. That workaround using my wife's MacBook Air for signing is not sustainable. I used AI assistance to determine the root cause. My DTS case 102877839447 is open but has not yet been forwarded to a DTS engineer. Environment Mac Mini M4, macOS 15.4.1 (Build 25E253) Xcode 26.4.1 (17E202) Team ID: Q23726668V (Computerade Products) Working comparison machine: MacBook Air, macOS 15.3 Precise Bug — Reproducible Every Time Every time Xcode generates a new certificate and key pair on my Mac Mini: Certificate: Apple Development: Michael Birch (9KD5TCGGHG) ✅ Private key: Apple Development: Michael Birch (Computerade Products) ❌ The key uses the organization name instead of the certificate identifier.

Is there a lower level diagnostic or fix beyond what the security command provides? The problem is specific to my Mac Mini M4 and persisted thru more than a year of Mac OS and xCode updates.

I’m seeing several Developer ID notarization submissions stuck in “In Progress” after an app transfer. This is for a macOS app distributed outside the Mac App Store. The app was recently transferred to a new Apple Developer team. After the transfer, notarization uploads succeed, but the submissions never complete. The app appears to be Developer ID signed correctly with the new team. I submitted the app through both Xcode Direct Distribution and command-line notarytool. The upload succeeds, but the submissions remain in “In Progress”, and no notarization log is available. Example submission IDs: 5e411dc6-0610-4f9c-8eef-e2a3d0b6a2fb 01bdeeda-3c7e-421a-ae72-6dc081b75e79 986b0c5e-e32f-489f-bc86-3b3c7d7ec91d 193f29b7-b23a-40e7-8324-c076859ca843 notarytool log returns: Submission log is not yet available or submissionId does not exist I also see older submissions from the previous day still stuck in “In Progress”, so this does not look like a normal notarization delay. I’m trying to determine whether this is caused by the recent app transfer / Team ID change, or whether there is anything else I can check locally. Questions: Is it expected for Developer ID notarization jobs to remain “In Progress” for more than a day with no log available? Is there any known issue with Developer ID notarization after an app transfer? If the upload succeeds but no log is ever generated, is there a recommended escalation path for stuck notarization backend jobs?

I work for a company which develops as part of our product suite a System Extension implementing an Endpoint Security client. Our local developer workflow for testing and validating changes is to build locally with Developer certificates (not a legitimate/production Developer ID certificate) and deploy local builds in to a VM, where to get the System Extension to load and be accepted we need to disable SIP & AMFI. macOS 27 VM is refusing to allow me to disable SIP. Is there an alternate approach we can use for this workflow to allow macOS VMs to accept our software when signing with a (same teamID, but different certificate to the provisioningprofile) developer certificate for local validation?

I have run into an interesting topic today. So far, I have been under the impression that when I am using the setCodeSigningRequirement() function on an NSXPCConnection, I am completely removing any chance of receiving AND sending messages to untrusted XPC Peers. However, I created a malicious replacement for my daemon, and I wanted to check if my application can still send and receive messages to it. I checked with codesign --verify that the replacement does NOT fulfil the code signing requirement. I put a system log instruction in the malicious tool's XPC function. When calling the XPC Peer, I expected to see: XPC connection to <redacted> failed! [Error Domain=NSCocoaErrorDomain Code=4102 "The code signature requirement failed." UserInfo={NSDebugDescription=The code signature requirement failed.}] and I did. However, I also saw the system log from the malicious tool's XPC function. Then, I checked all XPC documentation, and I found for the original C implementation - xpc_connection_set_peer_code_signing_requirement() - the following in the discussion section: All messages received on this connection will be checked to ensure they come from a peer who satisfies the code signing requirement. For a listener connection, requests that do not satisfy the requirement are dropped. When a reply is expected on the connection and the peer does not satisfy the requirement XPC_ERROR_PEER_CODE_SIGNING_REQUIREMENT will be delivered instead of the reply. (this is in xpc/connection.h) which seems to align with the observed results. However, this is (embarassingly?) new for me, I would have never expected this, given how in my head pre-checking before any connection is made seems straightforward, even with public Apple SDK APIs: Grab a SecCode (not SecStaticCode) object of the daemon (malicious or not). This is running code, so it cannot be substituted between the check and the outgoing message. Perform validations on the SecCode object in some form - on macOS 15.0+ it's pretty easy with LightweightCodeRequirement's SecCodeCheckValidityWithProcessRequirement(). Immediately drop the connection if the peer is untrusted, before any message is sent. Am I overlooking something or making wrong assumptions here? or Am I right and this is something that I have to accept that's implemented less than ideally and I can perform above steps 1-3 myself and make a difference? Thanks in advance!

Two months ago we got approval for using the Notification Filtering entitlement. We rushed out to implement it in our app, only to find out that the permission was set for the wrong bundle identifier. We expected to get the permission for the notification extension's bundle identifier, yet it is added for the main app's bundle identifier. Per the official docs, the entitlement permission should be in the notification service extension target: After you receive permission to use the entitlement, add com.apple.developer.usernotifications.filtering to the entitlements file in the Notification Service Extension target. However, this fails to get signed when compiling for non-simulator targets because of the bundle mismatch issue. Simulator perfectly filters notifications. Adding the entitlement to the main app does compile, but filtering does not work (as expected). We reached out to Apple twice (Case-ID: 14330583) but we have yet to receive any response. Could there be something else wrong instead of the identifier mismatch?

This post is a ‘child’ of Resolving errSecInternalComponent errors during code signing. If you found your way here directly, I recommend that you start at the top. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Fixing an untrusted code-signing certificate If your code-signing identity is set up correctly, selecting its certificate in Keychain Access should display a green checkmark with the text “This certificate is valid”. If it does not, you need to fix that before trying to sign code. There are three common causes of an untrusted certificate: Expired Missing issuer Trust settings overrides IMPORTANT When investigating code signing problems, don’t use sudo to run commands as root. This is a common source of confusion. I explain why in Resolving errSecInternalComponent errors during code signing. Check for an expired certificate If your code-signing identity’s certificate has expired, Keychain Access shows a red cross with the text “… certificate is expired”. If you try to sign with it, codesign will fail like so: % codesign -s "Apple Development" -f "MyTrue" error: The specified item could not be found in the keychain. If you use security to list your code-signing identities, it will show the CSSMERR_TP_CERT_EXPIRED status: % security find-identity -p codesigning Policy: Code Signing Matching identities 1) 4E587951B705280CBB8086325CD134D4CDA04977 "Apple Development: …" (CSSMERR_TP_CERT_EXPIRED) 1 identities found Valid identities only 0 valid identities found The most likely cause of this problem is that… yep… your certificate has expired. To confirm that, select the certificate in Keychain Access and look at the Expires field. Or double click the certificate, expand the Details section, and look at the Not Valid Before and Not Valid After fields. If your code-signing identity’s certificate has expired, you’ll need to renew it. For information on how to do that, see Developer Account Help. If your certificate hasn’t expired, check that your Mac’s clock is set correctly. Check for a missing issuer In the X.509 public key infrastructure (PKI), every certificate has an issuer, who signed the certificate with their private key. These issuers form a chain of trust from the certificate to a trusted anchor. In most cases the trusted anchor is a root certificate, a certificate that’s self signed. Certificates between the leaf and the root are known as intermediate certificates, or intermediates for short. Your code-signing identity’s certificate is issued by Apple. The exact chain of trust depends on the type of certificate and the date that it was issued. For example, in 2022 Apple Development certificates are issued by the Apple Worldwide Developer Relations Certification Authority — G3 intermediate, which in turn was issued by the Apple Root CA certificate authority. If there’s a missing issuer in the chain of trust between your code-signing identity’s certificate and a trusted anchor, Keychain Access shows a red cross with the text “… certificate is not trusted”. If you try to sign with it, codesign will fail like so: % codesign -s "Apple Development" -f "MyTrue" MyTrue: replacing existing signature Warning: unable to build chain to self-signed root for signer "Apple Development: …" MyTrue: errSecInternalComponent The message unable to build chain to self-signed root for signer is key. If you use security to list your identities, it will not show up in the Valid identities only list but there’s no explanation as to why: % security find-identity -p codesigning Policy: Code Signing Matching identities 1) 4E587951B705280CBB8086325CD134D4CDA04977 "Apple Development: …" 1 identities found Valid identities only 0 valid identities found IMPORTANT These symptoms can have multiple potential causes. The most common cause is a missing issuer, as discussed in this section. Another potential cause is a trust settings override, as discussed in the next section. There are steps you can take to investigate this further but, because this problem is most commonly caused by a missing intermediate, try taking a shortcut by assuming that’s the problem. If that fixes things, you’re all set. If not, you have at least ruled out this problem. Apple publishes its intermediates on the Apple PKI page. The simplest way to resolve this problem is to download all of the certificates in the Apple Intermediate Certificates list and use Keychain Access to add them to your keychain. Having extra intermediates installed is generally not a problem. If you want to apply a more targeted fix: In Keychain Access, find your code-signing identity’s certificate and double click it. If the Details section is collapsed, expand it. Look at the Issuer Name section. Note the value in the Common Name field and, if present, the Organizational Unit field. For example, for an Apple Development certificate that’s likely to be Apple Worldwide Developer Relations Certification Authority and G3, respectively. Go to the Apple PKI and download the corresponding intermediate. To continue the above example, the right intermediate is labelled Worldwide Developer Relations - G3. Use Keychain Access to add the intermediate to your keychain. Sometimes it’s not obvious which intermediate to choose in step 4. If you’re uncertain, download all the intermediates and preview each one using Quick Look in the Finder. Look in the Subject Name section for a certificate whose Common Name and Organizational Unit field matches the values from step 3. Finally, double check the chain of trust: In Keychain Access, select your code-signing identity’s certificate and choose Keychain Access > Certificate Assistant > Evaluate. In the resulting Certificate Assistant window, make sure that Generic (certificate chain validation only) is selected and click Continue. It might seem like selecting Code Signing here would make more sense. If you do that, however, things don’t work as you might expect. Specifically, in this case Certificate Assistant is smart enough to temporarily download a missing intermediate certificate in order to resolve the chain of trust, and that’ll prevent you from seeing any problems with your chain of trust. The resulting UI shows a list of certificates that form the chain of trust. The first item is your code-signing identity’s certificate and the last is an Apple root certificate. Double click the first item. Keychain Access presents the standard the certificate trust sheet, showing the chain of trust from the root to the leaf. You should expect to see three items in that list: An Apple root certificate An Apple intermediate Your code-signing identity’s certificate If so, that’s your chain of trust built correctly. Select each certificate in that list. The UI should show a green checkmark with the text “This certificate is valid”. If you see anything else, check your trust settings as described in the next section. Check for a trust settings override macOS allows you to customise trust settings. For example, you might tell the system to trust a particular certificate when verifying a signed email but not when connecting to a TLS server. The code-signing certificates issued by Apple are trusted by default. They don’t require you to customise any trust settings. Moreover, customising trust settings might cause problems. If code signing fails with the message unable to build chain to self-signed root for signer, first determine the chain of trust per the previous section then make sure that none of these certificates have customised trust settings. Specifically, for each certificate in the chain: Find the certificate in Keychain Access. Note that there may be multiple instances of the certificate in different keychains. If that’s the case, follow these steps for each copy of the certificate. Double click the certificate to open it in a window. If the Trust section is collapsed, expand it. Ensure that all the popups are set to their default values (Use System Defaults for the first, “no value specified” for the rest). If they are, move on to the next certificate. If not, set the popups to the default values and close the window. Closing the window may require authentication to save the trust settings. Another way to explore trust settings is with the dump-trust-settings subcommand of the security tool. On a stock macOS system you should see this: % security dump-trust-settings SecTrustSettingsCopyCertificates: No Trust Settings were found. % security dump-trust-settings -d SecTrustSettingsCopyCertificates: No Trust Settings were found. That is, there are no user or admin trust settings overrides. If you run these commands and see custom trust settings, investigate their origins. IMPORTANT If you’re working in a managed environment, you might see custom trust settings associated with that environment. For example, on my personal Mac I see this: % security dump-trust-settings -d Number of trusted certs = 1 Cert 2: QuinnNetCA Number of trust settings : 10 … because my home network infrastructure uses a custom certificate authority and I’ve configured my Mac to trust its root certificate (QuinnNetCA). Critically, this custom trust settings are nothing to do with code signing. If you dump trust settings and see an override you can’t explain, and specifically one related to code-signing certificate, use Keychain Access to remove it. Revision History 2026-07-02 Added a warning not to run tests using sudo. 2025-09-29 Added information about the dump-trust-settings command to Check for a trust settings override. Made other minor editorial changes. 2022-08-10 First posted.

One code signing issue I commonly see, both here on DevForums and in my Day Job™ with DTS, is that the codesign command fails with errSecInternalComponent. This issue crops up in a wide variety of circumstances and the correct fix depends on the specific problem. This post is my attempt to clarify the potential causes of this error and help folks resolve it. If you have any questions or comments about this, please start a new thread, tagging it with Code Signing so that I see it. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Resolving errSecInternalComponent errors during code signing In some circumstances the codesign command might fail with the error errSecInternalComponent. For example: % codesign -s "Apple Development" "MyTrue" MyTrue: errSecInternalComponent This typically affects folks who are signing code in a nonstandard environment, for example, when logged into a Mac via SSH or when signing code on a continuous integration (CI) server. This post explains how to resolve such issues, starting in the simplest case, signing from Terminal app, and then going on to discuss SSH and other contexts. IMPORTANT Before going further, make sure you understand the difference between a digital identity and a certificate. See TN3161 Inside Code Signing: Certificates for the details. Test from Terminal Code signing makes extensive use of the keychain, and that’s sensitive to the execution context in which it’s running. So, the first step in resolving this problem is to test your code signing from Terminal. To start, log in to the Mac using the GUI. Note If you don’t have access to the GUI, see Working without the GUI, below. Check that Keychain Access shows that your code signing identity’s certificate is trusted. Select the certificate and look for a green checkmark with the text “This certificate is valid”. If you see a red cross with an explanatory text like “… certificate is not trusted”, follow the instructions in Fixing an untrusted code signing certificate. Note macOS 15 moved Keychain Access out of the Utilities folder. The easiest way to find and launch Keychain Access is to use Spotlight. In Terminal, run the security tool to check that your code signing identity is available: % security find-identity -p codesigning Policy: Code Signing Matching identities 1) 4E587951B705280CBB8086325CD134D4CDA04977 "Apple Development: …" 1 identities found Valid identities only 1) 4E587951B705280CBB8086325CD134D4CDA04977 "Apple Development: …" 1 valid identities found If the identity is missing from the Matching identities list, you don’t have a code signing identity to sign with. If you see your code signing identity’s certificate in the keychain, it’s possible that you’re missing its private key. See Certificate Signing Requests Explained for more about that issue. If the identity is shown in the Matching identities list but not in the Valid identities only list, see Fixing an untrusted code signing certificate. This example assumes that you’re testing with an Apple Development signing identity. If you’re using something else, you’ll see a different identity name in this list. Use that identity name in the codesign command below. Still in Terminal, make a copy of the true tool to use for this test: % cp "/usr/bin/true" "MyTrue" Try to sign it: % codesign -s "Apple Development" -f "MyTrue" MyTrue: replacing existing signature The -f flag tells codesign to replace the existing signature. This command may display one or more keychain dialogs but, once you respond to those, it should correctly sign MyTrue. If it doesn’t, skip down to the Terminal failure section at the end of this post. Eliminate keychain alerts When you signed your code in the previous section, you may have seen one of two different types of keychain alerts: Keychain unlock dialog Access control list (ACL) dialog The keychain unlock dialog looks like this: codesign wants to use the … keychain. Please enter the keychain password. Password: [ ] [Cancel] [[OK]] The keychain containing your code signing identity is locked, and you must enter the keychain password to unlock it. You rarely see this dialog when logged in via the GUI because the system automatically unlocks the login keychain when you log in. However, the underlying cause of this alert will become relevant in the next section, when you log in via SSH. The ACL dialog looks like this: codesign wants to sign using key … in your keychain. To allow this, enter the … keychain password. Password: [ ] [Always Allow] [Deny] [[Allow]] The ACL for the your code signing identity’s private key prevents codesign from using the private key without your explicit approval. If you enter your password and click Allow, codesign can use the private key once. If you click Always Allow, the system adds codesign to the private key’s ACL so that it doesn’t have to ask again. To avoid this alert in the future, enter your keychain password and click Always Allow. Now repeat the codesign command from the previous section. It will sign the code without presenting any dialogs. Test over SSH Once you can sign your code in Terminal without seeing any dialogs, it’s time to repeat that process over SSH. To start, log out of the GUI and then log in via SSH. If you’re testing on a CI system, log in to that system by running ssh from Terminal on your Mac. If you want to test on your local Mac, choose one of these options If you have a second Mac, log in to that second Mac using the GUI, launch Terminal, and then run ssh to log in to your main Mac from there. If you have an iPad, use a third-party iPad SSH app to log in to your main Mac over SSH. Use a virtualisation app to run a macOS guest that you can treat like your CI system. Once you’re logged in over SSH, repeat the signing command from the earlier section: % codesign -s "Apple Development" -f "MyTrue" MyTrue: replacing existing signature MyTrue: errSecInternalComponent This fails because: The system locked the keychain when you logged out of the GUI. Logging in via SSH does not unlock the keychain. When codesign tries to use your code signing identity, the system attempts to present the keychain unlock dialog. That fails because you’re logged in via SSH and thus don’t have access to the GUI. The system returns the errSecInternalComponent error to codesign, which reports it to you. To fix this, unlock your keychain using the security tool: % security unlock-keychain password to unlock default: KEYCHAIN_PASSWORD % codesign -s "Apple Development" -f "MyTrue" MyTrue: replacing existing signature IMPORTANT This assumes that your code signing identity is in your login keychain. If it’s in some other keychain, read the security man page to learn how to unlock a specific keychain. Best practice is to store both parts of your code signing identity (the certificate and the private key) in the same keychain. If you split the identity across two keychains, unlock the keychain that contains the private key. Test your CI job Once you have everything working on your CI system over SSH, try running exactly the same commands in your CI job. If your CI system manages user contexts correctly, those commands should just work. If they don’t, discuss this with your CI vendor. Note macOS has a complex execution context model. For background on this, see the Execution Contexts section of Technote 2083 Daemons and Agents. Some CI systems don’t correctly establish a user context when running jobs. For example, they might switch the traditional Unix execution context — the EUID, RUID, and so on — but not the security context. This mixed execution context causes problems for the keychain, which relies on the security context. Avoid doing code signing work as root. Some folks run everything as root because they think it’ll avoid problems. When working with the keychain the opposite is true: Running as root often causes more problems than it solves. These problems are most likely to show up when you use sudo, which creates a mixed execution context. Working without the GUI The instructions above assume you have access to the GUI so that you can test and resolve issues using GUI tools like Keychain Access. However, many CI systems don’t give you access to the GUI; at best you might have interactive access using SSH. Note If you CI system allows remote access using a screen sharing protocol, use that rather than messing around with the instructions here. If you don’t have access to the GUI of the machine on which you’re signing code, there are three issues to deal with: Avoiding the keychain unlock dialog Avoiding the ACL dialog Investigating an untrusted code signing certificate issue To unlock the keychain, use the unlock-keychain subcommand of the security tool, discussed in the Test over SSH section earlier. When logged in with the GUI, you can respond to ACL dialog by clicking Always Allow. This prevents that dialog showing up again. However, if you don’t have GUI access there’s no way to click that button. To get around this, import your signing identity and set its ACL to allow codesign to use it without extra authorisation. To do this, first unlock the keychain: % security unlock-keychain password to unlock default: KEYCHAIN_PASSWORD Then use the security tool to import the PKCS#12 file: % security import IDENTITY.p12 -T /usr/bin/codesign -P P12_PASSWORD 1 identity imported. Note the -T option, which adds codesign to the private key’s ACL. Finally, modify the partition list to allow access by Apple code: % security set-key-partition-list -S "apple:" -l "Apple Development: …" This example assumes you’re using an Apple Development signing identity to test with. If you’re using something else, replace Apple Development: … with that identity name. Finally, investigating an untrusted code signing certificate issue remotely is quite challenging. Your best option here is to set up a local test environment, run your investigation in that environment, and then apply the results to your CI environment. There are two good choices for your local test environment: Use a virtualisation app to create a ‘clean’ macOS guest, one that’s never seen your code signing setup before. Use System Settings > Users & Groups to create a new local user account and do your testing there. The first option is best because you can easily restore your VM to a clean state between tests. When running through the process described in Fixing an untrusted code signing certificate, you might end up performing two different remedial actions: Importing an intermediate Reseting trust settings. Once you understand these remediations, you need to apply them to your CI system. The first one is easy: To import an intermediate, run security with the import subcommand: % security import INTERMEDIATE.cer 1 certificate imported. Resetting trust settings is more of a challenge. It’s probably possible to do this with the security tool but, honestly, if you think that your CI system has messed up trust settings it’s easiest to throw it away and start again from scratch. Terminal failure The bulk of this post assumes that the process described in the Test from Terminal section works. If it doesn’t, something weird is happening and you should apply the following diagnostic suggestions. The first is to create a new local user account on your Mac — using System Settings > Users & Groups — and then retry there. The goal of this test is to isolate: A problem that affects your Mac as a whole From a problem that’s tied to your user account If the problem is with your user account, switch back to your original account and run: % security dump-trust-settings SecTrustSettingsCopyCertificates: No Trust Settings were found. In most cases this should report that no trust settings were found. If it report trust setting overrides, remove them. See Check for a trust settings override in Fixing an untrusted code signing certificate. If that doesn’t resolve the issue, something else is afoot and I recommend that you seek dedicated help per the start of this post.

Xcode 27 creates a placeholder for the bundle identifier of a new project. devplaceholder.$(PROJECT_UNIQUE_VALUE:identifier).$(PRODUCT_NAME:identifier) I have two questions. Is it enough to change the bundle id from the Signing & Capabilities panel or do we need to change it somewhere else? What are Apple recommendations? Should we only replace the devplaceholder value and keep the unique value and product name, provide our won id but keep the product name, or replace everything with our own bundle ID? Thanks

We are facing following message "A timestamp was expected but was not found" during codesign for following .dylib and .pkg and it cause notarization process failed. We are facing this issue for last 3 days and we have access for timestamp.apple.com and 17.0.0.0/8 and we didn't change firewall settings. We are facing this issue randomly and not for all time(scenario is 3:1).

Hello, I have been unable to install any development-signed app on any physical device for five months. Builds succeed, code signing passes locally, but every device rejects the app at install time with: Failed to verify code signature of .../extracted/MyApp.app : 0xe8008018 (The identity used to sign the executable is no longer valid.) ApplicationVerificationFailed The app installs briefly, then iOS immediately removes it. This started right after my account (Team ID MB4DXDTDMT) was reinstated following a duplicate-account flag. Background: I had a personal account that was converted to a business account (Wakeout LLC), then created a new personal account, which Apple flagged as a duplicate and later reinstated. The signing failure began immediately after that reinstatement. Isolation already done (this is not a local-setup problem) I have run the full isolation sequence — including every step DTS typically asks for — and the result points squarely at the account/team, not my machine: New blank Xcode project, automatic signing, new bundle ID → same 0xe8008018. Brand-new macOS user account → same failure. Multiple Macs, fresh Xcode installs → same failure. Multiple iOS devices (iPhone 17 Pro, iPhone 15 Pro, others) → same failure. Different Apple ID / different developer team on the same Mac + same device → installs fine. This is the decisive one: the local environment is healthy; only Team MB4DXDTDMT is rejected. Xcode Cloud builds for this same team install fine. Apple's cloud signing trusts MB4DXDTDMT; the device-verification backend does not. That gap can only exist server-side. I have also: revoked/regenerated all certificates multiple times, deleted/recreated all provisioning profiles, cleared ~/Library/MobileDevice/Provisioning Profiles, cleared DerivedData and CoreDevice, removed device pairing records, re-paired devices, confirmed Developer Mode and correct system time. Simulators work. codesign --verify --deep --strict passes. Profile certificate SHA-1 matches the signing cert exactly. Entitlements match. Why I'm posting here This is the same failure documented in thread 755762, where Quinn concluded: "this seems to be tied to your primary developer account and only DevPrograms has access to those details." That matches my evidence exactly: the problem isolates cleanly to one team, and only DevPrograms can see the account-side state. I've already gone through Developer Support on this — an open case has been with them for about five months without a resolution, which is what convinced me the fix isn't something I can reach from the support side. I'm posting here in case a DTS engineer can confirm the diagnosis and point me to the right path. Question for any DTS engineer: given that the failure isolates to a single team — different teams sign and install fine on the same Mac and same device, and Xcode Cloud builds for this same team install fine — can you confirm this is an account-side signing-trust state that has to be reset by Apple, and what's the most direct way to get that reset actioned? Happy to attach a sysdiagnose, full console output, or codesign -dvvv dumps on request. Thank you.

I've been trying to notarize an installer (.pkg file) on a new laptop. Previous versions have been notarized successfully on a previous Mac. However, in spite of having the required certificates (same as the old Mac, generated for the new Mac) the submission gets stuck at "In Progress". Doing it multiple times (even hours apart) doesn't help. Is there a FAQ / suggested list of steps to help resolve this issue? Here's what I see: xcrun notarytool history --keychain-profile "(my profile name)" results in (problem started with v4, the first version I've tried on this new Mac): createdDate: 2023-10-17T01:34:36.911Z id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx name: xxxxxxxxxx-v4.pkg status: In Progress -------------------------------------------------- createdDate: 2023-10-17T01:33:59.191Z id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx name: xxxxxxxxxx-v4.pkg status: In Progress -------------------------------------------------- createdDate: 2023-10-16T21:01:25.832Z id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx name: xxxxxxxxxx-v4.pkg status: In Progress -------------------------------------------------- createdDate: 2023-10-16T19:57:44.776Z id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx name: xxxxxxxxxx-v4.pkg status: In Progress -------------------------------------------------- createdDate: 2023-10-02T14:17:34.108Z id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx name: xxxxxxxxxx-v3.pkg status: Accepted -------------------------------------------------- createdDate: 2023-09-28T14:04:46.211Z id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx name: xxxxxxxxxx-v2.pkg status: Accepted -------------------------------------------------- createdDate: 2023-09-20T17:28:46.168Z id: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx name: xxxxxxxxxx-v1.pkg status: Accepted -------------------------------------------------- xcrun notarytool log xxxxxxxxxxxxxxxxxxxx --keychain-profile "(my profile name)" results in: Submission log is not yet available or submissionId does not exist id: xxxxxxxxxxxxxxxxxxxxxxxx

macOS allows you to directly distribute a Network Extension using Developer ID signing, but with an important wrinkle. This post explains that wrinkle, its affect on Xcode, and how you get around it. If you have questions or comments, start a new thread here on the forums. Put it in the App & System Services > Networking and tag it with Network Extension. That way I’ll be sure to see it go by. Share and Enjoy — Quinn “The Eskimo!” @ Developer Technical Support @ Apple let myEmail = "eskimo" + "1" + "@" + "apple.com" Exporting a Developer ID Network Extension macOS supports a variety of Network Extension (NE) provider types. Starting with macOS 10.15, it’s possible to distribute an app containing NE providers directly, using Developer ID signing. See TN3134 Network Extension provider deployment for the full list of supported provider types. For your NE provider to work when distributed directly, it must: Be packaged as a system extension. Use Developer ID specific entitlements This post is focused on that second point, because it’s a common source of confusion. Note If you’re currently shipping an app extension and you want to move to a system extension, see Network Extension Provider Packaging. This post assumes that you’re building your app with Xcode; if you’re building your app outside of Xcode, you’ll have to adapt these steps to your build system. Entitlement Matters A Network Extension system extension and its container app must be signed with the Network Extension entitlement (com.apple.developer.networking.networkextension). That entitlement is an array, with a variety of different element values based on the provider type. For example, a standard NE content filter provider must include the content-filter-provider value. There are two groups of these values: the standard ones and the ones with the -systemextension suffix. During development and for App Store distribution, use the appropriate standard value. For direct distribution using Developer ID, use the corresponding value with the -systemextension suffix. For example, a Developer ID signed NE content filter must use content-filter-provider-systemextension instead of content-filter-provider. Xcode Issues IMPORTANT Xcode 27.0b1 is reported to have fixed this issue, meaning that it should now be possible to export a Developer ID signed app with an Network Extension system extension from the Xcode organiser. I did some basic tests of that here in my office and it seems to work. Yay! So the following is only relevant if you have to build your app with an earlier version of Xcode. Xcode 26 and earlier are not aware of this requirement. If you build your NE provider container app using Xcode, you might expect to export it for direct distribution using the Direct Distribution workflow in the Xcode organiser. This does not work on older versions of Xcode (r. 108838909). To get around this, manually export your app from your Xcode archive. Before attempting that, there are a few things to confirm: By default Xcode’s Signing & Capabilities editor uses the standard values for the NE entitlement. Leave them that way. During day-to-day development it’s best to use an Apple Development signing identity [1], and the standard values work with that. Continue to use Build > Archive [2] to create an Xcode archive for your product. The steps below replace the Direct Distribution workflow, and they assume you’re starting with an Xcode archive. Note For hints and tips about how to bring up and then debug an NE provider, see Debugging a Network Extension Provider. [1] Don’t use Developer ID for day-to-day development; see The Care and Feeding of Developer ID for more on that topic. [2] Or, if you’re automating this, the archive action in xcodebuild. Assemble Your Assets Imagine you’re working on a content filter for the Mac called WaffleFilter. You’ve used Xcode to build the app into an Xcode archive: % ls "WaffleFilter.xcarchive/Products/Applications" WaffleFilter.app That app is development signed: % codesign -d -vvv "WaffleFilter.xcarchive/Products/Applications/WaffleFilter.app" … Authority=Apple Development: … … IMPORTANT The steps in this section are based on the much more comprehensive instructions in Creating distribution-signed code for macOS. If anything is unclear, read that documentation for clarification. To re-sign this app for direct distribution you’ll need three things: A Developer ID application signing identity. This is named Developer ID Application: TTT, where TTT identifies your team. A Developer ID provisioning profile for the app. In this example I’ve called this WaffleFilter_Dev_ID.provisionprofile. A Developer ID provisioning profile for the system extension. In this example I’ve named this WaffleFilter_WFProvider_DevID.provisionprofile. If you’re not sure how to create these things, see Developer Account Help. Re-sign the App To start, make a copy of the app: % ditto "WaffleFilter.xcarchive/Products/Applications/WaffleFilter.app" "WaffleFilter.app" Dump the entitlements of the app and its embedded system extension: % codesign -d --entitlements "WaffleFilter.entitlements" --xml "WaffleFilter.app" % codesign -d --entitlements "WaffleFilter_WFProvider.entitlements" --xml "WaffleFilter.app/Contents/Library/SystemExtensions/com.example.apple-samplecode.WaffleFilter.WFProvider.systemextension" And reformat them to make them more readable: % plutil -convert xml1 "WaffleFilter.entitlements" % plutil -convert xml1 "WaffleFilter_WFProvider.entitlements" Now edit these files to add the -systemextension suffix. The result will look something like this: % cat "WaffleFilter.entitlements" … <dict> … <key>com.apple.developer.networking.networkextension</key> <array> <string>content-filter-provider-systemextension</string> </array> … </dict> </plist> % cat "WaffleFilter_WFProvider.entitlements" … <dict> … <key>com.apple.developer.networking.networkextension</key> <array> <string>content-filter-provider-systemextension</string> </array> … </dict> </plist> Before you re-sign with these entitlements, replace the embedded provisioning profiles with their Developer ID variants: % cp "WaffleFilter_Dev_ID.provisionprofile" "WaffleFilter.app/Contents/embedded.provisionprofile" % cp "WaffleFilter_WFProvider_DevID.provisionprofile" "WaffleFilter.app/Contents/Library/SystemExtensions/com.example.apple-samplecode.WaffleFilter.WFProvider.systemextension/Contents/embedded.provisionprofile" Now re-sign the app and the system extension with their new entitlements, from the inside out: % codesign -s "Developer ID Application" -f --entitlements "WaffleFilter_WFProvider.entitlements" --timestamp -o runtime "WaffleFilter.app/Contents/Library/SystemExtensions/com.example.apple-samplecode.WaffleFilter.WFProvider.systemextension" WaffleFilter.app/Contents/Library/SystemExtensions/com.example.apple-samplecode.WaffleFilter.WFProvider.systemextension: replacing existing signature % codesign -s "Developer ID Application" -f --entitlements "WaffleFilter.entitlements" --timestamp -o runtime "WaffleFilter.app" WaffleFilter.app: replacing existing signature If you have multiple Developer ID Application signing identities, you’ll need to replace Developer ID Application with the name of the specific identity you want to use. IMPORTANT If your app contains other code items, like frameworks or an app extension, re-sign those as well. For advice on how to manually re-sign a more complex app, see Creating distribution-signed code for macOS. And you’re done! Manually Notarise Xcode’s Direct Distribution workflow also deals with notarisation. As you’re not using that workflow, manually notarise your app. For advice on how to do that, see Customizing the notarization workflow. You should also look at Packaging Mac Software for Distribution, which has a bunch of general info about packaging Mac apps. Revision History 2026-06-22 Xcode 27.0b1 is reported to have fixed this issue. Added information about that. Made other minor editorial changes. 2023-09-21 First posted.

Hello. I am developing our company's SDK for iOS as a third-party library. This SDK consists of a static library and header files wrapped within a framework (and wrapping the target-specific frameworks in xcframework). I understand that codesign is required even for static frameworks, is it correct? Should I update the distributed files when the certificate expires? Does this depend on whether it is static or dynamic? When is the signature verified?

Hi, I recently enrolled in the Apple Developer Program and I’m trying to notarize my first Developer ID apps for distribution outside the Mac App Store. All of my valid notarization submissions are stuck in “In Progress”. The oldest one has been stuck since 2026-06-03, and newer submissions are stuck too. None of the valid submissions have moved to Accepted or Invalid, and no log is available. Team ID: TP32Y96XC5 Feedback Assistant: FB22994785 https://feedbackassistant.apple.com/feedback/22994785 Oldest stuck submission: 07865316-b2e0-4529-9790-97a63746d9a9 Hello Developer ID Test.dmg Created: 2026-06-03T12:20:18.595Z Status: In Progress This also happens with other apps/artifacts, so it seems like it may be account-level or team-level rather than an issue with one specific build. Other stuck submissions include: f1574597-154e-4386-a0b1-5560a57dde9d Azad IDE.zip Created: 2026-06-03T23:40:55.335Z aab15661-a883-413a-8a5d-8c78d1d0dabb Azad IDE.zip Created: 2026-06-05T11:29:46.664Z df4bb6dd-38fc-4083-92fa-d0846037fd53 MyMacOSApp-0.1.1-Darwin.dmg Created: 2026-06-05T11:52:54.093Z 305d56b7-a66a-4881-b649-c8738e39f3f2 Azad IDE.zip Created: 2026-06-08T10:58:24.724Z 1947d3c3-fc84-4479-9bee-355c16d51670 Azad IDE.zip Created: 2026-06-08T11:19:58.848Z What I checked: Developer ID certificate is installed and valid. The apps are signed with Developer ID Application: Matan Nahmani (TP32Y96XC5). codesign verification passes locally. Hardened runtime is enabled. notarytool authentication works. notarytool history/info works. notarytool log says the submission log is not yet available for the stuck submissions. I have not received a rejection email for the stuck submissions. Apple Developer System Status shows the notary service as available. Note: I do have one Invalid submission, but that one was intentional. I created it as a negative-control test while following a notarytool tutorial, to confirm that invalid submissions can produce a terminal status. The issue is that all valid Developer ID submissions remain stuck in In Progress. I understand that first-time notarization can take longer because of deeper analysis, but this has now been several days and every valid submission is still pending. Could someone from Apple DTS or the notarization team check whether Team ID TP32Y96XC5 is stuck in the first-time review/notarization queue? Thanks.

I've read Quinn's response on thread 827096 about Developer ID notarization submissions held for "in-depth analysis" on new teams. That guidance fits the general shape of what I'm seeing, but I'm posting a separate thread because (a) my situation does not involve an app transfer — these are the first-ever notarizations under a newly activated team, and (b) I've passed the "usually clears in a day or two" expectation and want to ask a few specific questions that thread didn't cover. Setup macOS app distributed outside the App Store Rust universal binary (aarch64-apple-darwin + x86_64-apple-darwin, merged via lipo) Binary signed with Developer ID Application, hardened runtime (--options runtime) and Secure Timestamp (--timestamp) .pkg built via pkgbuild + productsign with Developer ID Installer Team was activated 2026-05-29 — these are our first notarizations under the account, no prior submission history Submissions Submission A — submitted 2026-05-29T19:18:02Z, currently 100+ hours In Progress Submission B — submitted 2026-06-01, currently 30+ hours In Progress, identical polling behavior (Submission IDs available to DTS on request — happy to share via DM or via the Apple Developer Support case we have open on the same issue.) I submitted B specifically to test whether A was a one-off stuck queue entry. Both stalling identically rules that out and points at a team-level condition rather than a per-submission issue. xcrun notarytool log returns Submission log is not yet available or submissionId does not exist for both — same as the OP's experience on 827096. Local verification — every check in TN2206 passes $ pkgutil --check-signature .pkg Status: signed by a developer certificate issued by Apple for distribution Signed with a trusted timestamp on: 2026-05-29 19:15:36 +0000 Certificate Chain: Developer ID Installer: () Developer ID Certification Authority Apple Root CA $ codesign --verify --strict --verbose=2 valid on disk satisfies its Designated Requirement $ codesign --display --verbose=4 | grep -E '^(Authority|Timestamp|Runtime|TeamIdentifier)=' Authority=Developer ID Application: () Authority=Developer ID Certification Authority Authority=Apple Root CA Timestamp=May 29, 2026 at 12:13:40 PM TeamIdentifier= Runtime Version=26.5.0 xcrun notarytool history returns successfully and lists both submissions, so authentication and connectivity to the notary service are healthy. Developer System Status has shown the Developer ID Notary Service as "Available" throughout. Questions for DTS (Quinn or whoever picks this up) Quinn's 827096 reply describes "in-depth analysis" for new teams clearing in a day or two. Is there a known long-tail beyond that window, and is there anything a team can do to flag itself as ready for processing rather than waiting passively? Does resubmitting (as I did with submission B) extend, restart, or sit independently from the review of submission A? Is the review-completion clock driven by the team's activation date, the first submission, or the cumulative submission history? In other words, does each new submission help the team's signal, or does the system wait for the first to fully clear before evaluating subsequent ones? If we hit the 1-week mark Quinn referenced as the escalation tripwire without resolution, what's the recommended channel — a follow-up reply here, a new thread, Feedback Assistant, or another route? We also have an open Apple Developer Support case on this, currently silent for 4 days. Working that channel in parallel. Thanks in advance for any guidance — and thanks to Quinn for the public visibility he's given this pattern on 827096; it's the most useful documentation on it I've been able to find.

Hello Apple Developer Support Team, This is my first app submission.
