Xcode Automatic Signing Fails with App Groups - Provisioning profile "Mac Team Provisioning Profile : com.example.testapp.mobile" doesn't support the App Groups capability.
Xcode automatic signing consistently fails for the macOS target when adding the App Groups capability, even though the Developer Portal is correctly configured. Error: Provisioning profile “Mac Team Provisioning Profile: com.example.testapp.mobile” doesn’t support the App Groups capability. Setup: • Bundle ID: com.example.testapp.mobile • App Group: $(TeamIdentifierPrefix)group.com.example.testapp.mobile Troubleshooting Steps Tried (None Helped): • Changed bundle identifiers and deleted/recreated them in the Developer Portal • Deleted and recreated App Groups • Removed and re-added the developer account in Xcode • Deleted all provisioning profiles from the system • Cleared Derived Data and Xcode caches • Even tried on a clean macOS system This setup used to work previously. The issue seems to have started after the Apple Developer account was renewed.

Unable to test my apps, crashing with provisioning profile validation
Since around September (iOS 26 release), i'm unable to test my app normally. It says "internet connection is required to verify [my certificate id]", or just crashing. All terms and conditions accepted, everything is valid, certificates are OK. Reinstallation via xcode does not help. Removal of provisioning profile, generating new does not help. Revoking of certificate and generating new does for around week, then it happens again, but do i need to do it every week now? In logs i see the following: default amfid validation failed because of missing trust and/or authorization (0xe8008026) error amfid not valid: 0xe8008026: The provisioning profile requires online authorization. error amfid Unexpected MISError (0xe8008026): The provisioning profile requires online authorization. default +0300 amfid /private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib not valid: Error Domain=AppleMobileFileIntegrityError Code=-400 "An unknown error was encountered" UserInfo={NSURL=file:///private/var/containers/Bundle/Application/5B8E560E-75B2-46EF-8606-02072D99E9CF//Frameworks/oss.dylib, NSLocalizedDescription=An unknown error was encountered} default kernel AMFI: code signature validation failed. It looks like apple validation servers are not working, or is it iOS bug? All provisioning profiles are showing like "valid" in apple developer center. My network is not behind a proxy, connection is direct. If use EXACTLY the same app, signed with the same provisioning, same signature, on another test device, it works! When i reset current device to default settings and installing the EXACTLY same app after it, it works as well. Looking for a help from apple developer support

How to use the WebAssembly (wasm) binary module in macos App
During the release of our macOS App, we encountered the following issue: We need to support dynamic code loading of WebAssembly (wasm) inside our App, mainly by loading WebAssembly (wasm) binary modules. We discovered a problem: a wasm file is neither an executable nor a bundle, so it cannot be code-signed. Since our App needs to pass notarization, we have not set the com.apple.security.cs.allow-unsigned-executable-memory entitlement. Without setting com.apple.security.cs.allow-unsigned-executable-memory, loading a wasm module results in an “unsigned code” error that causes the process to crash. Could you please advise on what we should do to avoid this problem? Is it possible to apply for a special entitlement to allow com.apple.security.cs.allow-unsigned-executable-memory?

CarPlay Navigation Entitlement
We've been trying to get the CarPlay Navigation Entitlement for a couple years now without much luck. Did you have a similar experience? How did you succeed getting the entitlement? Part of the form requires us to submit Screenshots. Did you provide screenshots of your on-device experience or wireframe for CarPlay? How was your experience?

What is the right procedure for asking for entitlements ?
I want to use the com.apple.vm.networking entitlement which has a note: This entitlement is restricted to developers of virtualization software. To request this entitlement, contact your Apple representative. https://developer.apple.com/support/technical/ says: « Request entitlements using entitlement forms and ask for status updates in the resulting email thread. » but I haven't been able to find these "entitlement forms". Does anyone know what the right process is to request an entitlement?

Tap to Pay Entitlement only for development
Hi, We applied for Tap to Pay on iPhone entitlement and were approved, but on distribution support it's only showing Development. We can build and debug Tap to Pay on development, but unable to build release. We opened ticket with Apple support but they were saying it was configured correctly. I attached screenshot of our developer account entitlement for Tap to Pay. It clearly said Development only.

Notarization: "Team isn't configured for notarization"
I've tried to notarize my app recently and got the error:{ "logFormatVersion": 1, "jobId": "...", "status": "Rejected", "statusSummary": "Team is not yet configured for notarization", "statusCode": 7000, "archiveFilename": "myapp.dmg", "uploadDate": "2019-06-20T06:24:53Z", "sha256": "...", "ticketContents": null, "issues": null }I've never heard about "team configuration for notarization" previously. What are the steps to resolve that issue?Thanks in advance.

Cloud Signing via Developer ID doesn't seem to work with Admin API Keys
Hi, I'm having a really hard time figuring out why I cannot perform cloud signing via Developer ID with xcodebuild. I have a macOS application, which I can perfectly cloud sign the following way: Sign into Xcode with my Admin + Account Holder Apple ID. Delete my Developer ID Application certificate from Keychain Access. In Xcode, click Archive. When archived, click "Distribute App" in Xcode Organizer. The app is cloud signed. I prove this by extracting the certificate codesign --extract-certificates -- /path/to/app.app then locate the 1.2.840.113635.100.6.1.32 bit mentioned by Quinn in this post. I however do it by simply opening the certifiacte with Keychain Access, where I can investigate the content of the certificate, rather than use that tool he does. Then, I do the following to attempt to cloud sign via xcodebuild: Create an API Key for the whole team in Users and Access > Integrations > App Store Connect with the "Admin" role selected. Download the private key .p8 file to ~/Downloads. Sign out of my Apple ID in Xcode by removing the account in Settings > Accounts. Create an archive: xcodebuild archive -scheme "<redacted scheme name>" -archivePath ~/Downloads/archive.xcarchive -authenticationKeyIssuerID <redacted issuer id> -authenticationKeyID <redacted key id> -authenticationKeyPath ~/Downloads/AuthKey_<redacted key id>.p8 -allowProvisioningUpdates The archive is successfully created, with a new "Apple Development: Created via API (TEAM ID)" naming. Export the archive: xcodebuild -exportArchive -archivePath ~/Downloads/archive.xcarchive -authenticationKeyIssuerID <redacted issuer id> -authenticationKeyID <redacted key id> -authenticationKeyPath ~/Downloads/AuthKey_<redacted key id>.p8 -allowProvisioningUpdates -exportOptionsPlist ~/Downloads/exportOptions.plist -exportPath ~/Downloads which then fails: 2025-03-07 10:27:58.706 xcodebuild[2152:40704] [MT] IDEDistribution: -[IDEDistributionLogging _createLoggingBundleAtPath:]: Created bundle at path "/var/folders/tn/yy7ynz3d0yb4p3sd_5q_wl0h0000gn/T/<redacted app name> macOS_2025-03-07_10-27-58.706.xcdistributionlogs". error: exportArchive Cloud signing permission error error: exportArchive No signing certificate "Developer ID Application" found ** EXPORT FAILED ** Opening the distribution logs, I find this in the Provisioning Log: 2025-03-07 09:09:58 +0000 2025-03-07 09:09:58 +0000 IDEProvisioningRepair(<redacted app name>.app): 2025-03-07 09:09:58 +0000 IDEProvisioningRepair(<redacted app name>.app): Sending request 84E57539-BC1D-407A-8402-7BCE9F2FD100 to <https://appstoreconnect.apple.com/xcbuild/v1/certificates> for session DVTServicesTeamBasedSession <issuer: <redacted issuer id>; key identifier: <redacted key id>>.

Please contact your team's Account Holder or an Admin to give you access. If you need further assistance, contact Apple Developer Program Support at https://developer.apple.com/contact/." } ] } Which is really weird, since I am using an API key with Admin rights. If I create a new key, and use it only for this command, App Store Connect does show the "Last Used" date as today after running the command. I thought some time might need to pass, but the issue has been persisting since yesterday. What could be wrong here? I do have a managed Developer ID Application certificate showing in my account but I still can't retrieve it with an Admin right imbued API key.

"Provisioning profile does not allow this device" on Sequoia 15.2 VM
After upgrading the virtual machines used for building and testing our macOS application, it seems that something new in Sequoia is preventing virtual machines from running anything signed with a Mac Development certificate. At first glance the issue seems very similar to this thread, but it could be unrelated. We are using the tart toolset to build and run our VMs. People seem to be having related issues there with Sequoia in particular. I have added the VM's hardware UUID to the Devices list of our account. I have included that device in the devices list of our Mac Development provisioning profile. I have re-downloaded the profile, ensured that it is properly getting built into the app, and ensured that the hardware UUID of the VM matches the embedded provisioning profile: Virtual-Machine App.app/Contents % system_profiler SPHardwareDataType | grep UUID Hardware UUID: 0CAE034E-C837-53E6-BA67-3B2CC7AD3719 Virtual-Machine App.app/Contents % grep 0CAE034E-C837-53E6-BA67-3B2CC7AD3719 ../../App.app/Contents/embedded.provisionprofile Binary file ../../App.app/Contents/embedded.provisionprofile matches However, when I try to run the application, it fails, and while I have searched the system logs to find a more informative error message, the only thing I can find is that the profile doesn't match the device somehow: Virtual-Machine App.app/Contents % open ../../App.app The application cannot be opened for an unexpected reason, error=Error Domain=RBSRequestErrorDomain Code=5 "Launch failed." UserInfo={NSLocalizedFailureReason=Launch failed., NSUnderlyingError=0x6000039440f0 {Error Domain=NSPOSIXErrorDomain Code=153 "Unknown error: 153" UserInfo={NSLocalizedDescription=Launchd job spawn failed}}} Virtual-Machine App.app/Contents % log show --info --debug --signpost --last 3m | grep -i embedded.provisionprofile 2025-01-21 16:33:32.369829+0000 0x65ba Error 0x0 2872 7 taskgated-helper: (ConfigurationProfiles) [com.apple.ManagedClient:ProvisioningProfiles] embedded provisioning profile not valid: file:///private/tmp/builds/app/.caches/Xcode/DerivedData/Build/Products/Debug/App.app/Contents/embedded.provisionprofile error: Error Domain=CPProfileManager Code=-212 "Provisioning profile does not allow this device." UserInfo={NSLocalizedDescription=Provisioning profile does not allow this device.} I don't understand why the provisioning profile wouldn't allow the device if the hardware UUID matches. I have also attempted to add the Provisioning UDID in the devices list instead, but the form rejects that value because it's a different format (the form specifically requests a hardware UUID for macOS development, and a provisioning UDID for everything else). If there is any debugging tool that lets me check a provisioning profile against the running hardware and print a more verbose reason for why it's not allowed on the device, please let me know. Otherwise I'd have to conclude that, since I haven't experienced this issue before on an earlier OS, it has something to do with virtual machines running macOS Sequoia. (The same Mac Development-signed application runs just fine on my MacBook Pro running 15.2, as well as the VM host, which is also running 15.2.) I have also tried resetting the VM's hardware UUID and adding that one to the devices list, to no effect. This is obviously seriously impacting our CI/CD pipelines to allow for proper UI testing of our application. If anyone is aware of any workarounds, I would love to hear them!

Notarization Taking 20 Hours (and still counting)
I'm developing an app using Electron Builder for a potential port to Windows in the future. I've had a heck of a time getting credentials to work and felt like I was in some sort of time loop doing the same things over and over again to no avail. I finally was able to sign my app, sign the .dmg and start the notarization process. That was last night and it still says "In Progress". If anyone is able to push it through, that would be awesome! (id: 2520e724-7069-408a-9ea4-60b23e8435a7) I saw another thread on here where people stated it was taking forever, I'm not sure if this is just because its my first time, but I was hoping to get a beta out to testers this weekend. I just need a version that doesn't get flagged as "Malware" by Gatekeeper. This is just for a standalone macOS application, not the App Store. Is there a reason that this process takes an absurd amount of time? Will it always be like this or is this just a fluke and it was a bad time to try?

Unable to Staple Notarization Ticket – SSL Certificate Mismatch for oscdn.apple.com
Hello Apple Support, While attempting to staple a notarization ticket for our signed installer package, the stapler command fails with Error 65. Upon investigation, we found that connections to oscdn.apple.com present an SSL certificate issued to a248.e.akamai.net, which does not include oscdn.apple.com in its Subject Alternative Name (SAN). This mismatch prevents our macOS environment from validating tickets and completing the stapling process. Steps tried: Verified notarization status (Accepted). DNS flushed, tried different DNS (8.8.8.8, 1.1.1.1). curl to oscdn.apple.com consistently fails with SSL error 60. Please advise on resolving this certificate mismatch. also when I try to run the stapler command with my pkg "xcrun stapler staple/Users/mactest/Desktop/IPMPlus_Macos_Installer.signed.pkg" getting the output like :- Processing: /Users/mactest/Desktop/IPMPlus_Macos_Installer.signed.pkg Could not validate ticket for /Users/mac-test/Desktop/IPMPlus_Macos_Installer.signed.pkg The staple and validate action failed! Error 65. please help Thank you.

Can't publish to Testflight with Tap to Pay on iPhone entitlement despite it being granted
Hello, I went through the verification process to get the Tap to Pay on iPhone entitlement, and after a couple of corrections I was finally assured that I was granted the entitlement for production use. However, in App Store Connect, I can only see "Development" for "Provisioning Support" of the entitlement, and I'm not able to publish the app to Testflight because the profile doesn't support the entitlement (I'm using automatic code signing with XCode). Where is this going wrong? The Tap to Pay support assured me they granted the right entitlement and pointed me to the developer support. Thank you, Johannes

notarization suddenly stuck for hours
I've been successfully notarizing my apps for a year or so now, with intermittent releases every so often, usually succeeding with notarization in a couple of minutes. These apps are all written in Python, but I worked through all the jank required to get them to notarize cleanly a while ago and have no issues since. Today I submitted a couple of builds which have been stuck for hours. They're just "in progress", so no logs I can look at, no emails or anything on my developer account page. How can I begin to debug this? Successfully received submission info createdDate: 2025-06-24T18:43:37.140Z id: 8d1a1ca9-f0ad-426f-a714-89aaf9e01a07 name: pinpal-2025.6.25.for-notarizing.app.zip status: In Progress I should note that in addition to the comment added within 10 minutes of creation of this issue, within the last day, we also have: https://developer.apple.com/forums/thread/789389 https://developer.apple.com/forums/thread/789599 https://developer.apple.com/forums/thread/789995 So it seems pretty likely something is going on on the backend.

GateKeeper rejects application bundles with a file name with an NFC/NFD problem by copying with Finder
I made a macOS application using Swift Package and distributed it in dmg format through Apple Notary service. However, we received a report from a user that it can be launched from a disk image mounted from dmg, but when copied to /Applications, the app is broken and does not start. I looked into why this happened, I noticed that the codesign command returned different results when copying the application bundle and /Applications on the volume mounted dmg with Finder. Mounted dmg: OK ❯ codesign --verify --deep --verbose /Volumes/azoo-key-skkserv/azoo-key-skkserv.app /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: valid on disk /Volumes/azoo-key-skkserv/azoo-key-skkserv.app: satisfies its Designated Requirement Copied by Finder: Bad codesign reports that there are 148 added/missing files. ❯ codesign --verify --deep --verbose /Applications/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app: a sealed resource is missing or invalid file added: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...) file missing: /Applications/azoo-key-skkserv.app/Contents/Resources/AzooKeyKanakanjiConverter_KanaKanjiConverterModuleWithDefaultDictionary.bundle/Contents/Resources/Dictionary/louds/グ1.loudstxt3 (skip...) Copied by ditto: OK ❯ ditto /Volumes/azoo-key-skkserv/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app ❯ codesign --verify --deep --verbose /Applications/azoo-key-skkserv.app /Applications/azoo-key-skkserv.app: valid on disk /Applications/azoo-key-skkserv.app: satisfies its Designated Requirement I made a simple macOS application to explain this problem in an easy-to-understand way. You can download dmg in github releases, mount dmg, copy it in the Finder, and check if there is a problem by running the codesign command. https://github.com/mtgto/example-utf8-mac-notarization As a result, I learned the following two things. Occurs only with resources with file names whose values change due to NFC/NFD normalization No problems occur with the resources of the application itself. Generated by the Swift Package resources that the application depends on I think this is a problem with Finder or Gatekeeper.
