add /usr/bin/codesign to acl for private key
Displaying attribute for a private key I see a number of applications that are allowed to access it without needing a password e.g. racoon; Keychain Access.app; Certificate Assitant.app etc.. I want to add /usr/bin/codesign to the list but the gui window that pops up when I click on + doesn't seem to allow me to do that :( How do I do it please

Mismatch of TeamID while creating development certificate
Hi Team, I have created multiple certificates for macOS application. Below are the certificates created- Apple Development Certificate DeveloperID Installer Certificate Apple Distribution Certificate others certificates Later, I have imported the all these above certificates in keychain-access. Now, I tried to compile the code through Xcode. I am getting error for code signing certificate. Warning: unable to build chain to self-signed root for signer "Apple Development: Amit (M2WMF2YERI)” .... Command CodeSign failed with a nonzero exit code When I checked the TeamID of User(Amit) I can see that his current TeamID is [P8ZW3W9R2Q]. There is mismatch of teamID in apple development certificate generation. Note- All certificates are generated with current TeamID[P8ZW3W9R2Q] of user (Amit) except Apple Development certificate which has been generated with TeamID [M2WMF2YERI] which is generated with old TeamID of user (Amit). I attempted to generate the apple development certificate multiple times but it is getting generated with old TeamID TeamID[M2WMF2YERI] of user(Amit)
 Summary- While creating a developer certificate using apple developer account and mapping it in keychain, the certificate is being generated with old apple account details (Inactive) instead of the current one. This is causing issues when using the certificate in keychain. If anyone has encountered this issue, how it was resolved?

Codesigning in Europe still doesn't work with IPv6
I spent 20 minutes trying to figure out why codesigning was failing -- I had the pf block set up correctly, my keychains were unlocked, and then, eventually, it occurred to me, hey, maybe an IP address changed, so I disabled IPv6 except for link local, and then amazingly, it went back to working. I filed FB13706261 over a year ago. This is ridiculous.

Xcode archive DriverKit application
I am trying to build a release for an application that installs a DriverKit driver. I created a Developer ID Application Profile with a valid certificate but I'm coming across this error in Xcode 16.3 that is preventing me from archiving: Xcode 14 and later requires a DriverKit development profile enabled for iOS and macOS. Visit the developer website to create or download a DriverKit profile. I thought I needed a Dev ID Application profile to distribute the application and that a Development profile is for testing. Is there something I'm missing?

Unable to sign .app file with Developer ID installer certificate
I am using matlab to create an application (.app) using matlab application compiler. Along with that, I use matlab to create an installer for that. Unfortunately, the installer is in (.app) format. So do some custom things to install the dependencies and copying my application to Applications folder. I am able to sign the original application with Developer ID application certificate. But I am not able to sign the installer in .app format with Developer ID installer certificate. Is there any flag in any signing executable that allows me to use Developer ID installer certificate to sign .app file instead of typical (.pkg/.dmg)? Any help would be much appreciated.

After years, notarytool now cannot find Keychain item
For years, I've been shipping my apps with a Perl script that now invokes notarytool to get the notarization, using this command /usr/bin/xcrun notarytool submit --apple-id jerry@sheepsystems.com --keychain-profile SSYShipProduct --team-id 4MAMECY9VS --output-format json /Users/jk/blah/blah/MyApp.zip --wait I used this script with this command several times during September 2024 to ship my apps, and it worked. But now, the above command fails with: Error: No Keychain password item found for profile: SSYShipProduct Run 'notarytool store-credentials' to create another credential profile. Of course, I am now running later versions of macOS beta and Xcode than I was in September. Does anyone know the problem? Screenshots from Terminal and Keychain Access are attached. Thank you.

App Groups Entitlement Mismatch Between Provisioning Profile and Xcode Requirements for iOS App Extension
Hello Apple Developer Community, I'm experiencing a persistent issue with App Groups configuration for an iOS app extension that I can't resolve despite trying multiple approaches. I hope someone can help identify what I'm missing. Problem Description I'm getting this error when trying to build my iOS App Extension: Provisioning profile "iOS Team Provisioning Profile: com.idlrapp.Spleeft.SpleeftDataSaver" doesn't include the com.apple.developer.app-groups entitlement. My Setup Main App Bundle ID: com.idlrapp.Spleeft Extension Bundle ID: com.idlrapp.Spleeft.SpleeftDataSaver App Group ID: group.com.idlrapp.spleeft.shared Extension Type: Action Extension (Share Sheet) What I've Verified App Group Creation ✅ Created App Group group.com.idlrapp.spleeft.shared in Apple Developer Portal ✅ App Group shows as "Active" in the portal App ID Configuration ✅ Both App IDs (com.idlrapp.Spleeft and com.idlrapp.Spleeft.SpleeftDataSaver) have "App Groups" capability enabled ✅ Both App IDs are configured with the same App Group: group.com.idlrapp.spleeft.shared Entitlements Files Main App (Spleeft.entitlements): <key>com.apple.developer.app-groups</key> <array> <string>group.com.idlrapp.spleeft.shared</string> </array> Extension (SpleeftDataSaver.entitlements): <key>com.apple.developer.app-groups</key> <array> <string>group.com.idlrapp.spleeft.shared</string> </array> Xcode Configuration ✅ Both targets use "Automatically manage signing" ✅ Same Apple Developer Team selected for both ✅ App Groups capability shows correctly in Signing & Capabilities for both targets The Issue When I examine the downloaded .mobileprovision file, I can see it contains: <dict> <key>com.apple.security.application-groups</key> <array> <string>group.com.idlrapp.spleeft.shared</string> </array> <!-- Other entitlements... --> </dict> However, Xcode expects to find: <array> <string>group.com.idlrapp.spleeft.shared</string> </array> What I've Tried Multiple regenerations of provisioning profiles: Deleted all local provisioning profiles Toggled "Automatically manage signing" off/on Downloaded manual profiles from Developer Portal Verified App Group configuration: Double-checked App Group exists and is active Confirmed both App IDs have App Groups capability enabled Verified App Group assignment in both App IDs Entitlements cleanup: Ensured consistent App Group IDs across all files Removed duplicate/conflicting entries Clean builds and cache clearing: Product → Clean Build Folder Derived Data deletion Xcode restart Key Observation The provisioning profile contains com.apple.security.application-groups (which appears to be macOS-style) but Xcode expects com.apple.developer.app-groups (iOS-style) for the App Extension. Questions Is there a known issue with App Groups entitlement generation for iOS App Extensions? Should the provisioning profile contain com.apple.developer.app-groups instead of com.apple.security.application-groups? Is there a way to force regeneration of provisioning profiles with the correct entitlements? Are there additional steps required for App Extensions that differ from main apps? Any guidance would be greatly appreciated. This is blocking our App Extension development and we've exhausted our troubleshooting options. Thank you for your time and assistance.

keychain and codesigning local dev
Trying to play around with Secure Enclave Protected keychain operations in a Tauri-based MacOS app and running into issues. After much digging and trial and error, here is my understanding and where I'm at: To access these keychain related APIs, the app must be codesigned, and have the following entitlements: <key>com.apple.application-identifier</key> <string>XXXXXXXXXX.com.myorg.myapp</string> <key>com.apple.developer.team-identifier</key> <string>XXXXXXXXXX</string> <key>keychain-access-groups</key> <array> <string>XXXXXXXXXX.*</string> </array> Currently using a Development cert, generated from Xcode, not a paid account I had to install the intermediate cert from https://www.apple.com/certificateauthority/ XXXXXXXXXX is the "Team ID", which can be found on my Development cert under Details > "Organizational Unit" If I build the app and run it (without signing) I get code 34018 If I sign the app and try to run it, I am no longer able to boot it, with error: The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x12a60a130 {Error Domain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}} Not quite sure what is missing - any help is much appreciated.

Notarising two builds of the same app
I have built my application for arm and x64 so I have two files called DeepSkyStacker.app in different directories. I have followed the instructions to notarise the arm version of the app, but an concerned about what I should do to notarise the other one - do I just zip that up and then run: xcrun notarytool submit "DeepSkyStacker.zip" --keychain-profile "Notary Profile for DeepSkyStacker" --wait xcrun stapler staple DeepSkyStacker.app again or will that mess everything up? Related to that can I use the Notary Profile I created for DeepSkyStacker to notarise other apps that are part of the same product (DeepSkyStackerLive and DeepSkyStackerCL)?? Thanks David

App Group ID access for files after transfer ios
I have some questions regarding App Group Id's and use of the FileManager during an Appstore iOS transfer. I've read a lot of the topics here that cover app groups and iOS, but it's still unclear exactly what is going to happen during transfer when we try to release an updated version of the app from the new account. We're using this method FileManager.default.containerURL(forSecurityApplicationGroupIdentifier: "group.com.foo.bar") to store files on the device that are important for app launch and user experience. Once we transfer the app and begin the process of creating a new version under the new account will we be able to read the files that are stored using this app group id under the new account? What steps do we need to take in order to handle this and continue being able to access these files? It seems like the app group is not transferred in the process? I've seen some users mention they removed the app group from the original account and created it again under the receiving account (with notes mentioning this is undocumented behavior). These conversations we're centered around Shared user defaults, and that applies as well but I'm more concerned with reading the values from the file system. Thanks!

Electron and Notarization randomly failing.
I’m having trouble with the notary step of our electron app. It sometimes says “In progress” for days on end, where other times, it only takes 15-20 minutes. For the last few weeks, I’ve noticed that it will take longer than the 20 minutes if our app was using a not latest version of the electron module -- https://www.npmjs.com/package/electron. I would then update our codebase to build using the latest version, and then try to sign and notarize the app again, and it would work till a new version was released. This was the first time that that process didn’t work. Everything is on latest, and we’re still getting stuck “in progress” for days on end. We have been signing and Notarizing this app for years now, so it's not the first time we're trying to do this process To make matters stranger, I have two branches of the same exact code base – same dependencies, same source code, same everything – there is no difference. One sign and notarize works 100% of the time where the other one hasn’t worked yet. Any ideas would be helpful. I'm not really sure where to begin to debug this. Thanks!

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,

Notarization accepted, but the staple and validate action failed! Error 65.
Hi guys, I am new to publishing apps on Apple Store. I used python, pyside6, torch, pyinstaller to build an app for Apple Store. For codesigning, I used the correct "Developer ID Application" to sign the code. When I validate the .app file (codesign -vv --strict ), I got the following my_app.app: valid on disk my_app.app: satisfies its Designated Requirement Next, I used ditto to "ditto -c -k --sequesterRsrc --keepParent my_app.app my_app.zip" to zip it. Then, I submitted this my_app.zip file for notarization with "xcrun notarytool submit ..." and got the following "accepted" message. Received new status: Accepted Current status: Accepted............... [20:08:54.530Z] Info [API] Submission in terminal status: Accepted Processing complete After that, I want to staple it with "xcrun stapler staple my_app.app", but I got the following Could not validate ticket for my_app.app The staple and validate action failed! Error 65. To further investigate it, I ran "spctl -a -vvv my_app.app" and got my_app.app: rejected source=Unnotarized Developer ID origin=Developer ID Application... I don't know why this would happen after notarization accepted. Could someone help me understand this issue? Thanks!

We are building an installer application to install a dext. Building in Xcode, the installer app launches fine locally and installs the dext.

App works fine in development but crashes in hardened runtime
I am building an application using .NET and Avalonia UI. The application is cross-platform. One of the tasks of the application is to coordinate data collection that is then routed into a Docker container for analysis. Everything works as expected in Windows. Everything works as expected in macOS on the development workstation and before packaging. After I package/codesign into a hardened runtime, I start seeing crashes at the moment when I try to execute the system calls to Docker. I am reasonably confident that this has something to do with an entitlement flag or some other permissions issue. I have been trying to sort this on my own for a while. I am only hoping someone can nudge me in the right direction. Thanks, Kevin
