Notarization taking 12+ hours
I submitted a Mac application for a safari ad blocker extension about 15 hours ago and it's still in progress. Is it normal for notarization to take this long? It's my first time submitting something for notarization so maybe that's why it's taking longer than expected? ID: 8BDB3D5E-3A42-469F-9479-AC76229C6BB5

NotaryTool failing with invalid server certificate
Hi All. I'm having a notarization issue trying to get a product built. Starting around the beginning of April, I have a notarization process failing every time with an invalid server certificate. The returned error is: Error: HTTPError(statusCode: nil, error: Error Domain=NSURLErrorDomain Code=-1202 "The certificate for this server is invalid. You might be connecting to a server that is pretending to be “notary-artifacts-prod.s3.amazonaws.com” which could put your confidential information at risk." UserInfo={NSLocalizedRecoverySuggestion=Would you like to connect to the server anyway?, _kCFStreamErrorDomainKey=3, NSErrorPeerCertificateChainKey=( "<cert(0x107810200) s: *.s3.amazonaws.com i: Amazon RSA 2048 M01>", "<cert(0x107810c00) s: Amazon RSA 2048 M01 i: Amazon Root CA 1>", "<cert(0x107811400) s: Amazon Root CA 1 i: Starfield Services Root Certificate Authority - G2>", "<cert(0x107811c00) s: Starfield Services Root Certificate Authority - G2 i: Starfield Class 2 Certification Authority>" The problem certificate appears to be "Amazon RSA 2048 M01" which appears to be expired. The error fires in response to an 'xcrun notarytool log' command. The initial ' xcrun notarytool submit' has already worked. The build server in this case is running Jenkins, with a Makefile driven notarization stage. It all worked perfectly until a build on April 3rd, all builds have failed since. I have tried using '--no-s3-acceleration'. But that fails even faster with: Conducting pre-submission checks for ICFA.zip and initiating connection to the Apple notary service... Submission ID received id: d50a2157-7acb-4bd6-b1d1-6d0b1d52d5c9 Error: The operation couldn’t be completed. (Network.NWError error 2.) Any help or suggestions would be appreciated. Right now I have folks needing a valid build. Thanks in advance.

Are VisionOS Enterprise APIs handled differently from one another?
Hi, At work, we've done some development on an Apple Vision Pro. On the project, we used object tracking to track an object in 3D and found the default tracking refresh rate (I believe 5Hz)to be too slow so we applied for enterprise APIs so we could change it. At some point, in the capabilities (as a beginner to Swift and the Apple development environment) I noticed that's where you enable the Object Tracking Parameter Adjustment API and I did so, before hearing back about whether we got access to the enterprise API's and the license file that comes with it. So I setup the re-fresh rate to 30Hz and logged the settings of the ObjectTrackingProvider, showing it was set at 30Hz and felt like it was better than the default when we ran our app. In the Xcode runtime logs, there was no warning or error saying that the license file for the enterprise API was not found (and I don't think we heard back from Apple if they had granted our request or not - even if they did I think the license would be expired by now). Fast forward to today, I was running the sample code of the Main Camera access for VisionOS linked in the official developer documentation and when I ran the project in Xcode, I noticed in the logs that it wanted an enterprise license and that's why it wasn't running as expected in the immersive space. We've since applied for the Enterprise API for Main Camera Access. I'm now confused - did I mistakenly believe the object tracking refresh rate was set to 30Hz but it actually wasn't due to the lack of a license file/being granted access to the enterprise APIs? It seemed to be running as expected without a license file. Is Object tracking Parameter Adjustment API handled with different permissions than Main Camera Access API even though they are both enterprise APIs? This is all for internal development and not planning on distributing an app but I find the behaviour to be confusing between the different enterprise API? Does anyone have more insight as I find the developer notes on the enterprise APIs to be a bit sparse.

Can't enable an iOS Driverkit driver when using an older app ID
Hi there, We've discovered a problem with our iOS app. We've been attempting to add a Driverkit driver to it, but any time we run the app through Testflight, the driver installs fine, but when we go to enable the driver toggle in the app's settings, the toggle stays on, but in the device logs I can see: could not insert bundle at <private> into manager: <private> As you would expect - this means the driver is not actually enabled and does not respond to a device being connected to the iPad. This does not happen when building & running the app locally, nor does it happen when installing an Ad Hoc build. We also have a different app, not yet shipped. We are able to add the driver to that app without issue. It works after going through Testflight. What we have discovered now is that everything works fine even if we just create an entirely new app with it's own bundle IDs. I should point out that in all cases, we're keeping the capabilities the same for each of these apps/IDs - including the managed capabilities. The bundle IDs that have this problem are older (5 years old or more). It seems like any newer ID will work, but trying to add the driver (and the associated managed capabilities) to an older app/ID results in this vague error message, with no further details. If we inspect the resulting dexts, we can also see that the "Internal requirements code size" is different on the ones that fail. The failing ones have a size of 204 bytes, whereas the working ones all have a size of 220 bytes. Not sure if that's related but it's strikingly consistent. Does this mean there is an issue with older app IDs, and we need Apple to manually refresh them in some way before the driverkit capabilities will work after going through Testflight? We have two apps in this state, both are of the same vintage (~5 years+). We've been battling this issue for months on and off, so would appreciate some help.

"this identity cannot be used for signing code"
When building to macOS on GameMaker, I get the error "this identity cannot be used for signing code" when using the Developer ID Installer certificate. The certificate was neither expired nor revoked, but nonetheless I created new certificates to start fresh but am still getting that error. I don't get issues building to iOS via GameMaker, just to macOS. If it makes any difference, I only noticed this issue started happening after I converted my Apple Developer Program account from an individual account to an organizational account, although it was weeks to months before I built to macOS via GameMaker before then, so I don't know if it correlates with that.

Code Signing - Invalid Signature - Special Characters in Name, Team Name and Address
I was trying to put my game to test flight. I would test features like ads and in-app-purchases, then put on the Appstore(release). The game already works on Ipad. For test flight, the "automatically manage signing" option was enabled. Then I pressed the "archive" button. Built succeeded. Then I clicked the distribute button. That time, I had an error. "Upload failed, Invalid signature, App is not properly signed". I researched, and found special characters in name, team name and address can make errors. My name, address and team name have special characters(turkish). If it will be resolved, I want to re-write(fix) my name, team name and address. I already tried to change my name, team name and address from apple developer website but failed. They are asking a document of my identity of my new name but I didn't changed my name and address. Overall, there aren't any other facts that cause this issue as I know. If I send my current, unchanged identity and home address, could they allow to change(fix) them? On Console Log: DangerNo.app/DangerNo: ID : 6cfa13a9-685c-4df9-86dd-7506d67be8c5 DangerNo.app/Frameworks/UnityFramework.framework/UnityFramework: ID : 2b63aacc-9caf-453c-913f-bae0db14d363 My App ID : 6744022885 Error : Invalid Binary rejection email indicating a corrupted code signature was detected. Explanation : Invalid Signature - Make sure you have signed your application with a distribution certificate, not an ad hoc certificate or a development certificate. Verify that the code signing settings in Xcode are correct at the target level (which override any values at the project level). Additionally, make sure the bundle you are uploading was built using a Release target in Xcode, not a Simulator target. If you are certain your code signing settings are correct, choose "Clean All" in Xcode, delete the "build" directory in the Finder, and rebuild your release target.

Third party SDKs signing requirement and expiration
Hi, I have some doubts about certificates expiration given this "new" requirement around signing for some common third party SDKs: https://developer.apple.com/support/third-party-SDK-requirements/ Use case: I build an SDK that will be distributed as an XCFramework and will be used in AppStore apps from different people. My SDK internally uses some other third party libraries that are integrated as binaries Let's assume some of those third party libraries are from the list above and therefore seem to be required to be signed. I distribute my SDK with all in order (third party SDKs from that list with valid signatures) People using my SDK over the time provide an update to their apps on the AppStore but by then some of the third party libraries of my SDK has an expired certificate. What would happen? People using my SDK won't have any issues as far as my SDK has a valid signature (despite third party libraries from the list have expired signatures) People using my SDK will get a warning about it but still will be able to submit to the AppStore. In that case, would AppStore Review process decline the update? People using my SDK will get an error, not being able to submit to the AppStore and will require me an update version of the SDK with those third party libraries re-signed. My understanding is that all would work as far as my SDK has a valid signature (after all is the one taking responsibility of the code inside), independently of what happens with the signature of those libraries themselves, am I correct?.

Getting a public service app not to send scary messages
I’ve developed a macOS app, but I’ve had trouble using a script to fully codesign it and package it into a .dmg file. I was only able to complete codesigning using the third-party app itself—not via command-line scripts. Is it possible to write a script that automates the entire process of codesigning the app? To provide the best user experience for those downloading the app outside of the Mac App Store, is it correct to first package it as a .app and then wrap that into a .dmg file for distribution? Currently, the app is available on the web as a .dmg. When downloaded, it appears in a folder and can be double-clicked to launch. However, macOS displays a warning that it was downloaded from the internet. Can I use a script to remove that quarantine warning? If possible, I’d appreciate a step-by-step explanation and a sample command-line script to: Codesign the app properly Package it into a signed .dmg Remove the quarantine attribute for local testing or distribution Is the reason I was only able to codesign it inside the third-party app due to how that app was built, or can this always be done from the command line?

Keychain Data Recovery After App ID Prefix Update
We had an issue with IDrive Online Backup which has started discussing on the Developer forum at https://developer.apple.com/forums/thread/756904 and as suggested raised a technical support ticket Case-ID: 7747625. At last the old legacy bundle ID prefix changed to to the new Team ID prefix. As a result  one-time loss of keychain data occurs, however we requested and were granted an additional keychain capability that allowed access to keychain data stored under the old legacy prefix, even after transitioning to the new Team ID prefix. We are currently facing a similar challenge with our other application, IBackup. As with the earlier case, we had a mismatch between the App ID prefix and the Team ID, which we resolved by updating the prefix to match the Team ID. Again now encountered a blocker with Keychain data recovery. We have already requested the additional Keychain capability that would allow access to keychain data stored under the old legacy prefix, even after transitioning to the new Team ID prefix. Unfortunately, the team responsible for this has some uncertainty about the process. Please review the details under case 102398017929 and extend this capability to our application to ensure a seamless user experience.

I got my app notarized but I am still getting the malware warning message
Hello, I recently had my Electron app notarized by Apple and then performed the following steps: Stapling the Notarization Ticket: xcrun stapler staple "appPath/Aiparalegal.app" Zipping the App for Distribution: ditto -c -k --keepParent "appPath/Aiparalegal.app" theAIParalegal.zip However, after unzipping and attempting to launch the app, macOS displays the following message: Apple could not verify "theAIParalegal" is free of malware that may harm your Mac or compromise your privacy. Yet, when I run validation using: xcrun stapler validate "theAIParalegal.app" I receive confirmation: The validate action worked! I then tried restarting my computer but the problem persist Could you help me understand why the notarization validation appears successful, yet macOS still displays this security warning? Any advice on how to resolve this would be greatly appreciated. Thank you!

Inquiry about CarPlay Entitlements Application - Black Box Integration for Device Settings & Communication - No Response After 7 Days
Hi everyone, I applied for CarPlay Entitlements on [Date 4. 26, 2025] using. (*CarPlay Entitlements Case-ID : 13045151) I haven't received any updates or responses regarding my application yet. It's been 7 days since the application. My service requires CarPlay integration with a Black Box device. The primary purpose of this integration is to allow users to configure device settings through CarPlay. Furthermore, we plan to utilize the "Communication" category of Entitlements to notify users of parking incidents detected by the Black Box device while parked. This functionality is crucial for alerting drivers to potential issues affecting their vehicles. Could anyone share their experience with the typical turnaround time for CarPlay Entitlements, especially for applications involving device integration and the "Communication" category? Is this delay normal? Is there any way to check the application status or contact the appropriate team to inquire about its progress? Thank you for any insights or advice you can provide! Sincerely,

codesign fails with no explanation
When I first tried to sign my local unit test with the identity generated by Xcode, it failed because the intermediate certificate was missing. In that case, the error message explained that the trust chain could not be completed. But after installing the correct intermediate, codesign still fails, but no longer gives any explanation: codesign -f -s '0EFE7E591A4E690842094B8EC5AFDFE059637D3C' build/Darwin-Xcode-arm64_obf/bin/Release/UNITTEST build/Darwin-Xcode-arm64_obf/bin/Release/UNITTEST: replacing existing signature build/Darwin-Xcode-arm64_obf/bin/Release/UNITTEST: errSecInternalComponent It's the same error line "errSecInternalComponent". Is there a log somewhere that might explain what exactly is the error?

Notarize taking 24+ hours to complete
I have been notarizing the same program for 3 years now and it's usually completed in minutes. I have not changed anything on my end, is there a reason it's taking 24+ hours all of a sudden? I have seen the posts regarding this issue for new applications where it has to "learn", but I have been notarizing the same apps for 3 years now.

CodeSign with out Certificate and Profile
We are facing issue with resigning the app which is developed by 3rd party. In this app we have Sharing functionality feature for which we have enabled Associated Domains capability. When we are signing the app with our certificate and profile this functionality is not working i.e when we are clicking on shared link in the app it is redirecting to app store page instead of content link. However, when 3rd party is directly using our certificate & profile then that functionality is working as expected. Could you please help us with the above issue why it is not working when we are resigning with our certificate and profile?

Replacing binary within app (in-situ upgrade) without breaking signing?
Yes, this is very likely the completely wrong way to do things but I would like to ask regardless. Currently with windows/linux I can perform an in-situ upgrade of an application by performing a download of the binary 'foo' and then doing a rename-and-replace and subsequently requesting the licencee to restart the program and all is good. With macOS, as the binary is within the foo.app ( Contents/macOS/foo ) I imagine I cannot perform a similar operation without breaking the signing of the foo.app itself? ....or, can I individually sign the binary foo for macOS and perform the same type of operation? Download new foo as foo.new rename current foo.app/Content/macOS/foo -> foo.old rename foo.new -> foo Restart application Again, I know this is very likely an un-macOS way of performing the task but as you can imagine with supporting cross-platform development it's usually easier to maintain a consistent method even if it's "not ideal".
