Certificate Active in Keychain and I think Xcode but Not Recognized by VS Code / Flutter on macOS Tahoe (macOS 15)
Hi, hoping someone can help here. I recently updated my Mac to macOS 15 (Tahoe) and am using Xcode 15+ (possibly 16). I’m working on a Flutter app and testing on a real iPhone device. Here's the situation: I’m using the free Apple Developer account. My signing certificate and provisioning profile both show as valid and active in Keychain and says "signing..." in Xcode. When I build and run the app from Xcode, it works completely fine on a simulator. But when I try to run the same project from VS Code using flutter run, whether on an simulator phone or my personal iphone, I get a code signing error, specifically: Failed to codesign Flutter.framework with identity... I believe the app is set to use the correct Team ID because it says my name and (team) (my team ID isBDKUKWVRBY), and I can see my certificate in Keychain under "My Certificates". What I’ve already tried: flutter clean pod install / pod update Manually selecting my team in Xcode Signing settings Restarting my machine and VS Code Confirming the same project builds on other machines Verified provisioning profile is assigned to the project in Xcode deleting and recreating a certificate I have even had AI inside VS code take a shot at it and that couldn't fix either My question: Why would VS Code / Flutter not be able to use the same certificate and signing setup that works in Xcode? Is this an issue with Flutter tooling on macOS 15, or do I need to reconfigure signing differently now? Any suggestions or fixes would be greatly appreciated!

help needed for signing certificate for Developer ID Application.
1.Provisioning profile "xxx" doesn't include signing certificate "Developer ID Application: xxxxx". 2.Provisioning profile "xxx" doesn't match the entitlements file's value for the com.apple.developer.networking.networkextension entitlement. I decoded the profile, <dict> <key>com.apple.developer.system-extension.install</key> <true/> <key>com.apple.developer.networking.networkextension</key> <array> <string>packet-tunnel-provider-systemextension</string> <string>app-proxy-provider-systemextension</string> <string>content-filter-provider-systemextension</string> <string>dns-proxy-systemextension</string> <string>dns-settings</string> <string>relay</string> <string>url-filter-provider</string> <string>hotspot-provider</string> </array> <key>com.apple.security.application-groups</key> <array> <string>xxxxx</string> <string>xxxxx</string> </array> <key>com.apple.developer.networking.vpn.api</key> <array> <string>allow-vpn</string> </array> <key>com.apple.application-identifier</key> <string>xxxxx</string> <key>keychain-access-groups</key> <array> <string>xxxxx</string> </array> <key>com.apple.developer.team-identifier</key> <string>xxxxx</string> </dict> Kindly help me to resolve this.

How to move code signing certificates to another Mac
Hi, I recently created and installed new code signing certificates/keys on my main Mac. How to easily copy these certificates/keys to my another Mac with the same Apple ID? Earlier Quinn suggested: "The easiest way to do this is use Xcode’s import/export feature. Launch Xcode, choose Xcode > Settings, select Accounts, select the account in question, then choose Export Apple ID and Code Signing Assets from the action (…) menu." And it worked fine in 2020-2021. However import/export options are no longer available in XCode 16 anymore. Please suggest a simple solution.

Failed Qualification After Receiving Default Mail Capability
Hi Apple DTS & community folks, I’m reaching out regarding an issue we’ve encountered with the com.apple.developer.mail-client capability for our app (bundle identifier: so.notion.Mail). We were granted this entitlement last week to allow the app to be set as a default Mail client. While everything works as expected when archiving and distributing builds locally in Xcode, we’re running into a problem when using Xcode Cloud. Specifically, Xcode Cloud attempts to archive and distribute an Ad-Hoc build, but the Ad-Hoc provisioning profile does not include this special entitlement. Since we’re using Xcode-managed profiles, we don’t have the ability to create or adjust an explicit profile ourselves. This issue only arises in Xcode Cloud—local distribution works unless we explicitly attempt an Ad-Hoc build (which is not our intent). I’ve included a screenshot of the error for reference. We found this forum post describing the same issue, where the resolution was Apple enabling the entitlement for Ad-Hoc builds. We’d like to request that Apple enable this capability for Ad-Hoc builds for the Notion Mail application so that Xcode Cloud distribution functions correctly. Thank you for your help!

Inquiry Regarding Gatekeeper Behavior During Application Upgrade
Can you please help us with the scenario below, including details and Apple’s recommendations? I've already read through the Notarization and Gatekeeper documentation. The installed version of our application is 1.2.3, located in /Applications/XYZSecurity.app. We created an upgrade package for version 1.2.4. As part of the pre-install script in the 1.2.4 installer, we explicitly deleted some obsolete .dylib files from /Applications/XYZSecurity.app/Contents/Frameworks and some executable files from /Applications/XYZSecurity.app/Contents/MacOS that were no longer needed in version 1.2.4. The installation of version 1.2.4 completed successfully, but we see the below error logs in installer.log: PackageKit: Failed to unlinkat file reference /Applications/XYZSecurity.app/Contents/Frameworks/libhelper.dylib PackageKit: Failed to unlinkat file reference /Applications/XYZSecurity.app/Contents/MacOS/helper-tool Our Key Questions: Is it the right practice to remove obsolete files in the pre-install script during an upgrade? Is this approach recommended by Apple? Can this cause any issues with Apple Gatekeeper? Is there a possibility of my application getting blocked by Gatekeeper as a result?

Xcode not recognizing approved User Assigned Device Name capability in provisioning profile
Hi, I am experiencing an issue where Xcode displays a "Provisioning profile doesn't support the capability" error for the User Assigned Device Name capability, despite it being approved by Apple and visible in our provisioning profile on the Developer Portal. Background We have completed and submitted the required capability request form to Apple for the User Assigned Device Name capability and received approval. The capability appears correctly in our provisioning profile on the Apple Developer Portal and shows among the enabled capabilities alongside other standard capabilities like In-App Purchase and Push Notifications. Issue However, Xcode consistently displays the error message when trying to enable the User Assigned Device Name capability in our project settings, preventing successful builds with this functionality. Troubleshooting Steps Attempted We have tried multiple troubleshooting steps including: Regenerating provisioning profiles Performing clean builds Clearing DerivedData Manually installing profiles Adding the com.apple.developer.device-information.user-assigned-device-name entitlement manually to our entitlements file Toggling automatic signing on and off Environment Details Xcode Version: 16.4 (16F6) iOS Deployment Target: iOS 13 Profile Type: Distribution provisioning profile Capability: User Assigned Device Name Despite the capability being approved by Apple and visible in our provisioning profile, Xcode does not recognize it. This appears to be a synchronization issue between the Apple Developer Portal and Xcode's capability validation system. Has anyone encountered similar issues with recently approved capabilities, specifically the User Assigned Device Name capability? Could you please provide guidance on how to resolve this capability recognition issue? Any suggestions for resolving this discrepancy between the Developer Portal and Xcode would be greatly appreciated.

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.

Notarization of Electron MacOS App taking too long
I started the notarization process for my electron app (just a browser window loading a URL) yesterday (26/03/2025) at around 05:23 GMT. I noticed in a couple of posts here in the forum that it may sometimes take a day to notarize the first app submitted by a team, but it has been over 30 hours since I submitted the app for notarization Here's the log. createdDate: 2025-03-26T05:23:11.102Z id: ddcb3fca-4667-4acb-8fd1-3298a7c244cc name: xolock-browser.zip status: In Progress Is there any reason why it is taking so long? Thanks in advance!

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!

Provisioning profile doesn't support the External Link Account capability
Hello, i have a problem. From one day to another i get following error (I never experienced this error with the same profile before) while trying to build and release my app via fastlane: exportArchive Provisioning profile "" doesn't support the External Link Account capability. Looking in the App developer website, it seems, that the existing and valid profile includes this capability. On the other side, inspecting the profile via xcode profile download, there is no hint that this capability is enabled. Any suggestions? Thanks!

codesign Failure with errSecInternalComponent Error
I am experiencing a persistent issue when trying to sign my application, PhotoKiosk.app, using codesign. The process consistently fails with the error errSecInternalComponent, and my troubleshooting indicates the problem is with how the system accesses or validates my certificate's trust chain, rather than the certificate itself. Error Details and Configuration: codesign command executed: codesign --force --verbose --options=runtime --entitlements /Users/sergiomordente/Documents/ProjetosPhotocolor/PhotoKiosk-4M/entitlements.plist --sign "Developer ID Application: Sérgio Mordente (G75SJ6S9NC)" /Users/sergiomordente/Documents/ProjetosPhotocolor/PhotoKiosk-4M/dist/PhotoKiosk.app Error message received: Warning: unable to build chain to self-signed root for signer "(null)" /Users/sergiomordente/Documents/ProjetosPhotocolor/PhotoKiosk-4M/dist/PhotoKiosk.app: errSecInternalComponent Diagnostic Tests and Verifications Performed: Code Signing Identity Validation: I ran the command security find-identity -v -p codesigning, which successfully confirmed the presence and validity of my certificate in the Keychain. The command output correctly lists my identity: D8FB11D4C14FEC9BF17E699E833B23980AF7E64F "Developer ID Application: Sérgio Mordente (G75SJ6S9NC)" This suggests that the certificate and its associated private key are present and functional for the system. Keychain Certificate Verification: The "Apple Root CA - G3 Root" certificate is present in the System Roots keychain. The "Apple Worldwide Developer Relations Certification Authority (G6)" certificate is present and shown as valid. The trust setting for my "Developer ID Application" certificate is set to "Use System Defaults". Attempted Certificate Export via security: To further diagnose the problem, I attempted to export the certificate using the security find-certificate command with the exact name of my identity. Command executed (using double quotes): security find-certificate -c -p "Developer ID Application: Sérgio Mordente (G75SJ6S9NC)" &gt; mycert.pem Error message: security: SecKeychainSearchCopyNext: The specified item could not be found in the keychain. The same error occurred when I tried with single quotes. This result is contradictory to the output of find-identity, which successfully located the certificate. This suggests an internal inconsistency in the Keychain database, where the certificate is recognized as a valid signing identity but cannot be located via a simple certificate search. Additional Troubleshooting Attempts: I have already recreated the "Developer ID Application" certificate 4 times (I am at the limit of 5), and the issue persists with all of them. The application has been rebuilt, and the codesign command was run on a clean binary. Conclusion: The problem appears to be an internal macOS failure to build the trust chain for the certificate, as indicated by the errSecInternalComponent error. Although the certificate is present and recognized as a valid signing identity by find-identity, the codesign tool cannot complete the signature. The failure to find the certificate with find-certificate further supports the suspicion of an inconsistency within the keychain system that goes beyond a simple certificate configuration issue. I would appreciate any guidance on how to resolve this, especially given that I am at my developer certificate limit and cannot simply generate a new one.

Mac catalyst stuck at notarize
I have created a Mac Catalyst version of the same app, and it was transferred from an old account to a new one. However, the Mac Catalyst build has been stuck in progress for several days when attempting to notarize it. After many days, I got the rejection with the following error: Team is not yet configured for notarization. Please contact Developer Programs Support at developer.apple.com under the topic Development and Technical / Other Development or Technical Questions. I have already tried to create a new developer ID certificate, but it still has the same issue. On the other hand, the iOS app is working fine and has been published in the App Store. Could you please assist us in resolving this issue as quickly as possible? Your prompt help would be greatly appreciated.

PKG Installer Fails Notarytool Submission Process
I am trying to get a PKG installer through the Apple codesign and notarytool process. When I submit the PKG installer I get a status message of "Invalid" and when I review the log file it has 2 errors. For "status summary" it says: "Archive contains critical validation errors", and for "message" it says" "The binary is not signed". The installer contains a flat file that is installed in the "Users/Shared" folder via the PKG installer. Here are the steps I've taken to get the installer through the codesign and notarytool process. codesign the file that's placed in the "Users/Shared" folder: codesign --options=runtime --sign 'Developer ID Application: XYZ' -v /Users/.../Documents/folder/"flat file" which I get a message saying "signed generic". Create the PKG installer with the signed "flat file". Sign the PKG installer containing the signed "flat file": codesign --options=runtime --sign 'Developer ID Application: XYZ' -v /Users/.../Documents/folder/"flat file" which I get a message saying "signed generic". Submit the PKG file with notarytool: xcrun notarytool submit /Users/.../Documents/folder/"flat file" --verbose --apple-id username --password password --team-id ID# --progress It completes and provides the submission ID. I check the status and get the error message that it's invalid. When I check the full details via the log I get the error messages mentioned above. What am I missing or failing to do?
