Local DriverKit development blocked by provisioning profile requirement
Hi, I am working on a personal HIDDriverKit project. The documentation suggests that you do not need the entitlements from Apple to do local development - that all you need to do is turn of SIP, enable developer mode, and turn signing to "Sign to Run Locally". However, I have followed all of these steps, and am still running into the error that to build, I need to have a provisioning profile with the DriverKit (development) feature (MacOS 15.2 Xcode 16.2). Am I missing something here regarding the steps for local development? Does one need to request a development version of the entitlements even for local development? Do I need a paid developer account to do this? Thank-you in advance.

Code-signing and Notarization Accepted, but Stapler Fails with Error 65
Hello Apple Developer Community, I’m encountering an issue where my macOS app (signed with a valid ‘Developer ID Application’ certificate and accepted by Apple’s notary service) fails when I attempt to staple the notarization ticket. The Apple notary service reports ‘Accepted’ each time, but xcrun stapler staple always returns Error 65, with the local check (spctl -a -vvv) showing ‘Unnotarized Developer ID.’ Here are some key points: Certificate: I have a valid ‘Developer ID Application’ certificate (unexpired) in my login and system keychains, with Apple’s intermediate certificates also installed and set to System Defaults or Always Trust. Notarization: Regardless of whether I submit a .zip of the .app or the final .dmg for notarization, notarytool reports ‘Accepted.’ Stapling: xcrun stapler staple (or notarytool staple) on the exact file I uploaded fails with Error 65, claiming it can’t validate the downloaded ticket. Environment Checks: Checked for duplicate or outdated certificates—only one Developer ID remains. Repeated on multiple code-signed builds (both .app and .dmg) with the same result. Manually tested code-signing the .app with entitlements (for the hardened runtime) and then signing the .dmg without entitlements. Logs: The relevant excerpt from stapler indicates “Could not validate ticket for [app]. The staple and validate action failed! Error 65,” even though Apple’s notary service claims success. Could you please advise any additional troubleshooting steps or possible causes for local validation failure after a successful notarization? I’ve already ensured the environment is up to date with valid intermediates, only one Developer ID certificate. Any insight on diagnosing ticket mismatch or known tool bugs with Error 65 would be appreciated. Thank you!

Error 65 upon stapling - cannot reset trust settings
Hi, I'm getting error 65 upon stapling and I am suspecting that non-default trust settings may be the reason as outlined here: Unfortunately whatever I do, I can't seem to reset the trust settings to their default values (removing the blue/white "+"), I'm not being asked for credentials upon closing the certificate window. I have also tried to unlock the System Roots key chain, to no avail. Also, when running security dump-trust-settings -d I get Number of trust settings : 0 for all certificates. Any ideas as to what I may be doing wrong? Is there any other setting that may be involved? Thanks!

Code signing error.
There is something wrong with my keychain.

Notarization service says signature invalid, but codesign says it's fine
I'm trying to get an app notarized, which fails with this error: The signature of the binary is invalid. However, locally checking the signature does succeed: $ codesign -vvv --deep --strict TheApp.app […] TheApp.app: valid on disk TheApp.app: satisfies its Designated Requirement Performing this check on every single item in the app's MacOS folder also succeeds. Context: embedded prebuilt binaries Now, the app has something unusual about it: it embeds prebuilt binaries, arranged in various nested folders. So, the app bundle's MacOS folder actually contains another folder with a whole tree of executables and libraries: Removing these (before building) does fix the notarization issue, but obviously I'd like to keep them in. I did my best to properly sign these items: At build time, they're copied into the product by a Copy Files phase (but not signed), then signed by a script phase That signing uses the same signing identity as the running Xcode build, and enables the hardened runtime The app builds and runs correctly, even as a release build The app has runtime hardening and app sandbox enabled How should I go about diagnosing the notarization issue?

Apple Developer Certificate not recognized for codesigning
I’m building an Electron app for macOS that I plan to distribute to users in a .dmg outside the Mac App Store. I have a Developer ID Application certificate (from Apple’s Developer Portal) and a private key, and I can see “Developer ID Certification Authority” in my System Roots keychain. • My Developer ID Application certificate is in the login keychain, and it shows up under “My Certificates” with its private key. • On Keychain, certificate shows red message "not trusted", but when I evaluate and check it specifically for codesigning it shows a green checkmark and success • Developer ID Certification Authority is in System Roots. • security find-identity -p codesigning – shows my certificate, but shows 0 valid identities • Updated operating system and deleted and recreated a new certificate, still get the same issue

Apple Notarization: Long running notarization jobs / day limitation
Dear Apple support, Since the last couple of days, we have some (very) long running notarization requests. Similar requests were done normally under 1 minute. This behavior is unexpected to us, and we did not see it before. The issue occurs for a small CLI tool submitted as a ZIP archive. Checking the documentation, I come across the section about "Avoid long notarization response times and size limits" (https://developer.apple.com/documentation/security/customizing-the-notarization-workflow#Avoid-long-notarization-response-times-and-size-limits). One fact is mentioned “Limit notarizations to 75 per day.” What is behavior if that limitation is reached? Is that limitation per Apple ID or per team ID? Are there some known issues about Notarization Service? Best regards, Stefan

Endpoint Security entitlement while in dev
I'm working on a system extension leveraging endpoint security entitlement. However, while in development, is there a way to continue working and testing locally without having the endpoint security entitlement approved or needing the extension signed. I got these errors running a build: Provisioning profile "Mac Team Provisioning Profile: "com.xxxxx.extension" doesn't include the com.apple.developer.endpoint-security.client entitlement.

Notarization.
Hi, I've code-signed my app and notarized it, and created a DMG, and when I slacked it or airdropped it to someone for testing the FIRST time they open it, they get a warning that it was Slacked or airdropped to them and do they want to open it. if they say yes everything is fine. So looking through here someone said I need to sign the app and then make a dmg and sign the dmg and then send that for notorization and then staple that. So I did, and I still get a warning the first tie someone try's to run it. What am I doing wrong? I know I can buy software and not get a warning from apple. so how do I get my app to work correctly like that?

NSTask launchRequirementData
I've noticed that NSTaks has this property as of macOS 14.4 @property (nullable, copy) NSData *launchRequirementData API_AVAILABLE(macos(14.4)) API_UNAVAILABLE(ios, watchos, tvos, visionos); It has no documentation whatsoever. Even google search has no clue. Does this have anything to do with code signature requirements validation? Any explanations and examples would be appreciated!

Apple Certification Expired
Hello everyone. I have a simple doubt, I receive an email informing that the Apple Distribution certificate will expire. I create one new in the Developer portal with one year duration. My doubt is, I need to do something more like open again the app in Xcode, insert new certificate and build it again, send to apple and everything? Or just creating this certification is enough? Is possible to increase this certification time or auto renew? Thank you!!!

Handling Permissions After Transferring macOS App to a New Developer ID
I have a macOS application that was previously distributed under my personal Apple Developer account using a Developer ID certificate. We’ve recently transitioned distribution to our company’s Apple Developer account. The app’s bundle identifier has been successfully transferred, and I’ve signed a new build of the app using the company’s Developer ID certificate. The app installs and runs correctly under the new signature. However, I’ve encountered a problem: the app is no longer able to access previously granted permissions (e.g., Screen Recording, System Audio Recording, and Input Monitoring). Furthermore, it cannot re-prompt for these permissions because they appear as already granted in System Settings. From what I understand, this issue is due to the change in the code signing identity. Specifically, the designated requirements used by macOS to identify an app have changed, so the system no longer associates the new version of the app with the previously granted permissions (as outlined in Apple's Technical Note TN3127). The only workaround I’ve found so far is to manually reset the app's permissions using Terminal commands (e.g., tccutil reset), but this is not something we can reasonably ask end users to do. Question: Is there a recommended or supported approach to either preserve permissions when changing Developer ID identities, or programmatically trigger a permissions reset for existing users? We're looking for a seamless solution that doesn't degrade user experience.

Problems with new Developer ID certificate
My Developer ID certificate will expire in few days, so I downloaded and installed new certificate in login keychain. However my key is still linked to my old certificate. I have my .p12 but even if I delete the old certificate from login keychain and reinstall the .12 file, my old certificate reappears in the login keychain. I tried to select the new certificate in the login keychain and choose Files > Export Items (in Keychain Access) but in the Save dialog under File Format the "Personal Information Exchange (.p12)" option is grayed out. How can I generate a key/.p12 file that will be linked to my new certificate?

When to notarize artifacts developed in different stages?
Dear Apple Support, for better understanding to use the Notary Service, I would like to ask when and what have to be notarized. I am absolutely aware of using the Notary Service and which packages can be submitted and how to get the status. Scenario: We have one library which is developed by a specific team and other teams develop and deliver to customer MacOS apps which packages this library for the shipment. So, the library will be produced internally and will be shipped in different products. The library will be code signed before we make available internally. When should we notarize (and staple) this library? Directly after the code is signed or when it will be packaged in each product when it will be delivered to customer? Best regards, Stefan

No iOS signing identities match the specified provisioning profile
Hello, I get this message when building from a .net maui app. I think I followed all the steps. I've downloaded my provisioning profile from developer.apple.com and my instructions (you tube) said to double click it and XCode will open. It does that but I don't see where the provisioning profile goes in xCode. I followed another link which told me to delete everything in /Users/username/Library/MobileDevice/Provisioning Profiles and after doing that I don't see any files reappearing when I click the provisioning profile from finder. Did I mess myself up following internet articles again? I'm running XCode Version 16.2 (16C5032a) under accounts I can see my appleid linked but I don't see the provisioing profile I loaded. Sorry very new at Mac development (and kinda cheating using Maui) Save me apple gods, Steven

Developer ID Certificate (How to replace damaged certificate?)
How do I replace an Apple Developer ID Certificate that indicates it is not trusted? When I look at my Certificate Expiring 02-20-2025, I see a valid status displayed. (See annotation #1.) However, when I look at my Apple Developer ID Certificate renewal, I see the words not trusted. (See annotation #2.) I downloaded the renewal certificate and double double-clicked the downloaded item to place it in my KeyChain. This certificate period is from 01-21-2025 to 01-22-2030. QUESTIONS Why does the renewal certificate say "certificate is not trusted"? (Its period is 01-21-2025 to 01-22-2030. Today is 01-27-2025.) How did the renewal certificate get damaged? What must I do to get the damaged certificate replaced with a valid one?

MacOS PKG Notarization status is Rejected with status code 7000
I developed a macOS application and have already signed the pkg package. However, when I submitted it for notarization using the following command: xcrun notarytool submit --signed.pkg --apple-id "**@gmail.com" --team-id "2*******M" --password "this is password" --wait I received a "Rejected" status. The log provided the following details: "logFormatVersion": 1, "jobId": "f5f3751d-b449-4a2f-b905-32d38ab5963b", "status": "Rejected", "statusSummary": "Team is not yet configured for notarization.
