Legacy Team ID prevents adding AppClip
My iOS app was created with a legacy Team ID in 2011. When I try to add an AppClip to the app, the Team ID on the AppClip is the new Team ID. Xcode prevents the build from completing. The com.apple.developer.parent-application-identifiers entitlement (null) of an App Clip must match the application-identifier entitlement ('TYXXXXXP2.com.it-guy.MyApp') of its containing parent app. How can this be resolved? Can the AppClip Team ID be changed in "Identifiers" on the developer.apple.com?

Xcode Automatic Signing Failure After Adding Keychain Capability – Mac Device Incorrectly Identified as iPod
Environment: MacBook Air Apple M2 (macOS Tahoe 26.1) Xcode 26.0 (17A324) Automatic signing enabled Feedback ID: FB21537761 Issue: I'm developing a multiplatform app and encountered an automatic signing failure immediately after adding the Keychain capability. Xcode displays the following error: Automatic signing failed Xcode failed to provision this target. Please file a bug report at https://feedbackassistant.apple.com and include the Update Signing report from the Report navigator. Provisioning profile "Mac Team Provisioning Profile: com.xxx. xxx" doesn't include the currently selected device "FIRF‘s MacBook Air" (identifier 00008112-000904CA3441xxxx). What I've Investigated/Tried: Checked the developer account devices and found that the device with identifier 00008112-000904CA3441xxxx is incorrectly labeled as an “iPod” (it is actually my MacBook Air). Attempted to manually enroll the Mac again, but it still appears as an iPod in the device list. Tried creating a provisioning profile manually, but no devices are available for selection in the device list when generating the profile. Question: Has anyone encountered a similar issue where a Mac is misidentified as an iPod in the developer portal, leading to provisioning failures? Any suggestions on how to resolve this or work around the device recognition problem? Thank you in advance for your help.

Notarization Rejection - The binary is not signed with a valid Developer ID certificate
Notarization Rejects Valid Developer ID Certificates - Apple Infrastructure Issue? Environment macOS: 15.6.1 Xcode: 26.0.1 Architecture: arm64 (Apple Silicon) Team ID: W---------- Certificate Status: Valid until 2030 (verified on developer.apple.com) Problem Apple's notarization service consistently rejected properly signed packages with error: "The binary is not signed with a valid Developer ID certificate." Despite: ✅ Valid certificates on developer.apple.com ✅ Local signing succeeds (codesign --verify passes) ✅ Proper certificate/key pairing verified ✅ Package structure correct Failed Submission IDs September 2025: adeeed3d-4732-49c6-a33c-724da43f9a4a 5a910f51-dc6d-4a5e-a1c7-b07f32376079 3930147e-daf6-4849-8b0a-26774fd92c3c b7fc8e4e-e03c-44e1-a68e-98b0db38aa39 d7dee4a1-68e8-44b5-85e9-05654425e044 da6fa563-ba21-4f9e-b677-80769bd23340 What I've Tried Re-downloaded fresh certificates from Apple Developer Portal Verified certificate chain locally Tested with multiple different builds Confirmed Team ID matches across all configurations Verified no unsigned nested components Waited 3 months for potential propagation delays Verified all agreements are current and accepted Re-tested with minimal test package - same error persists Local Verification # Certificates present and valid security find-identity -v -p codesigning | grep "Developer ID" 1) XXXXXXXXXX "Developer ID Application: <<REDACTED>> (W----------)" 2) XXXXXXXXXX "Developer ID Installer: <<REDACTED>> (W----------)" # Signing succeeds codesign --verify --deep --strict --verbose=2 [app] → Success Question This appears similar to thread #784184. After 3 months and ensuring all agreements are signed, the issue persists with identical error. The certificates work for local signing but Apple's notarization service rejects them. Could this be: Backend infrastructure issue with Team ID W----------? Certificate not properly registered in Apple's notarization database? Known issue requiring Apple Support intervention? Has anyone else experienced valid Developer ID certificates being rejected specifically by the notarization service while working locally?

VM App - PCIDriverKit Entitlement for Thunderbolt
I want to help contribute a feature in a virtual-machine app in macOS that supports PCIe device passthrough over thunderbolt. I have a question about the entitlements. Since I do not represent the GPU vendors, would I be allowed to get a driver signed that matches GPU vendor IDs? Is there such a thing as wildcard entitlement for PCIDriverKit? I don't want end-users to have to disable SIP to be able to use this. Any suggestions/leads? Thank you.

Notarization wipes the "Icon?" file
In an AppleScript applet, compiling and exporting in Script Editor replaces a custom icon with the default. To retain a custom icon, it is necessary, after exporting, to use Finder's "Get info..." to copy the icon from another file and paste into the icon for the applet. The custom icon is stored in the "Icon?" file, located in the root of the applet bundle. The applet can then be signed and notarized. With macOS Tahoe, that procedure no longer works. That is because the notarization process now wipes the "Icon?" file. The file remains in place but has zero size. Thus Finder shows the default applet icon. Does anyone know of a way to provide a custom icon for a signed and notarized AppleScript applet ?

'Certificates, IDs & Profiles' section missing from developer.apple.com
The entire 'Certificates, IDs & Profiles' section is missing from developer.apple.com portal for one of the accounts I am a developer for. The Team is also missing from the dropdowns in Xcode in Code Signing. The organization account membership is paid through July 2026, and I do not see that the Account Holder needs to sign any agreements. I am a user on other accounts, and none of them have this issue. Does anyone know what's going on?

How to properly register a macOS System Extension in an Electron app?
Hi everyone, I’m developing an Electron application on macOS and I’m trying to register and activate a macOS System Extension, but I’m running into startup and entitlement issues. 🔧 What I’m trying to build • An Electron app packaged with electron-builder • Signed with Developer ID Application • Notarized using @electron/notarize • A macOS System Extension is already built and signed • The System Extension provides a virtual camera • I wrote a Swift helper that: • Registers / activates the virtual camera • Calls OSSystemExtensionManager • This Swift code is compiled into a .node native addon • The .node module is loaded and called from Electron (Node.js) to trigger system extension registration ❗ The problem When I add the following entitlement: com.apple.developer.system-extension.install the application fails to launch at all on macOS. Without this entitlement: • The app launches normally • But system extension activation fails with: Error Domain=OSSystemExtensionErrorDomain Code=2 Missing entitlement com.apple.developer.system-extension.install With this entitlement: • The app does not launch • No UI is shown • macOS blocks execution silently 🤔 My questions 1. Is it valid for an Electron app’s main executable to have com.apple.developer.system-extension.install? 2. Does Apple require a separate helper / launcher app to install system extensions instead of the Electron main app? 3. Are there any Electron-specific limitations when working with macOS System Extensions? 4. Is there a known working example of Electron + macOS System Extension? 5. Do I need a specific provisioning profile or App ID capability beyond Developer ID + notarization?

Application has stopped verifying
We package a nightly build of our application for distribution. About 1 month ago, this package has started showing the "Apple could not verify 'Application' is free of malware" message.

Declared Age Range API Capability for Enterprise App
Hey Apple Friends, We currently have an enterprise version of our app for debugging and internal distribution. Our release configuration uses our App Store account. However, it appears you cannot add a 'Declared Age Range' to the Enterprise app as a capability making it impossible to debug because we have added the 'Declared Age Range API' locally, but we cannot add it as a capability on the dev portal. Is there any work around for this?

WatchOS Companion app on VPP Crashing on Launch
Hello, I sent this in as a feedback several weeks ago about watchOS 26.2 beta 2 but since the issue is still active now that watchOS 26.2 is in production I'm reposting here for the community. I would also like to submit a DTS about this issue but honestly don't know the best way to go about it and would appreciate advice about that. There seems to be an issue with VPP distribution for our app on watchOS 26.2. When our watchOS companion app is launched after being installed through VPP to a supervised iPhone, it encounters a dyld error before main() or any application code is even called. The same app launches correctly in every other circumstance we could imagine and test: – Installed through VPP on supervised devices running watchOS 26.1. – Installed from the app store (using an apple id) on a supervised iPhone and paired watch running iOS 26.2 / watchOS 26.2. – Installed through Testflight on a supervised iPhone and paired watch running iOS 26.2 / watchOS 26.2. – Installed through the app store on unsupervised devices running watchOS 26.1 and 26.2. This strongly appears to be a VPP signing issue because we even did the following experiment: Install iPhone and Watch apps through the App Store on a supervised device pair running public iOS 26.2 beta 2 / watchOS 26.2 beta 2. Verify that both apps launch successfully. Use an MDM command to install from VPP over the existing installations Verify that the watch app fails to launch (the iOS app is unaffected) My feedback included some crash logs which I won't be reposting publicly here. Any feedback or ideas appreciated.

My Notifications Message Extension doesn't seem to run after distributing my app via Enterprise IPA
I'm developing an app that receives push notifications, and writes the contents of the push notification to a shared location between the main app and a Notifications Message Extension, through App Groups. This all seems to work on my phone, with developer mode turned on, but when I archive my app as an Enterprise IPA and distribute it, the users can install the app on their phones and they receive the push notifications, but it doesn't appear that the message extension is running as my app displays the content of the shared data in the App Groups on the main screen and nothing is showing. I have tried on 3 phones, and it only works on the phone with developer mode turned on. I can't tell at this point whether it's because of a signing issue, or build phase order issue, or something else?

Provisioning profile failed qualification - SensorKit Reader Access entitlement issue during app distribution
Hello, I'm currently developing an iOS app that uses SensorKit. Everything works fine in development and testing — the app correctly requests and receives SensorKit permissions on test devices. In my App ID configuration, the SensorKit Reader Access entitlement (com.apple.developer.sensorkit.reader.allow) is included and visible in Xcode under the project’s entitlements list. However, when I try to archive and distribute the app, I get the following errors in Xcode: Provisioning profile failed qualification Profile doesn't support SensorKit Reader Access. Provisioning profile failed qualification Profile doesn't include the com.apple.developer.sensorkit.reader.allow entitlement. Even though my provisioning profile includes this entitlement, Xcode still refuses to distribute the app. Here’s what I’ve confirmed so far: The provisioning profile lists com.apple.developer.sensorkit.reader.allow in its entitlements. SensorKit works perfectly in debug and development builds. The issue only occurs when attempting to distribute (Archive → Distribute App). Could this be because my account has only development entitlement for SensorKit and not the distribution entitlement? If so, how can I verify or request the proper distribution entitlement for SensorKit Reader Access? Thank you for any guidance or confirmation from Apple regarding this entitlement behavior.

Error when updating system extension
I'm currently observing a problem similar to this thread https://developer.apple.com/forums/thread/737334 The difference is that this is happening after updating a system extension. Basically same error, sysextd complains it can not check that the system extension is notarized: macOS Error 3 + Error code=-67050. I think macOS (Sequoia 15.3.2 or 15.7.2 if it matters) is wrong in this case for the following reasons: when using spctl assess -t install, the system extension is reported to be correctly notarized. when restarting the Mac, the updated system extension is correctly checked and staged. if I run spctl assess before sysextd tries to check the system extension, it works. I'm currently thinking of 2 reasons why the check does not work: sysextd is somehow trying to work with a cached assessment that has become invalid after the system extension was updated. macOS needs way more time between the update of the files and the request to update the staged extension. I tried adding a 5-second delay. This does not seem to work or at least reliably. I tried just touching the system extension, no positive result. Unfortunately, in macOS Sequoia, it is not possible anymore to reset-default using spctl and see if it solves the issue, at least the next time the update is performed. [Q] Is there some magic operation that would help macOS correctly check the notarization of an updated system extension?

Notifications filtering request - do we need separate approvals for apps belonging in the same account?
I have two apps - say A and B in my AppStore account, deployed in the AppStore. App A has obtained the com.apple.developer.usernotifications.filtering entitlement and this is added to my AppStore account by Apple after approval. Note that this is added for the account, and not for the specific app. Now, my app B also wants this functionality. Followed all the steps as done for app A - adding the already approved entitlement to my app B's identifier, regenerating the profiles, adding the key in the entitlements file, calling the completion handler with empty content like - contentHandler(UNNotificationContent()) Still the notifications show, the filtering is not working. Do I have to request the entitlement for App B separately? Even if I do request again, I am not sure if there is going to be any difference in the steps already done. The difference can only be if Apple has a mapping with the app id internally in their system, for the filtering to work? If I have white-labelled versions of apps A or B, do I have to request again then? Or does Apple restrict only one app to have this entitlement from one AppStore account? Please guide on the next steps here.

Renaming notarized ZIP packages
Dear support team, is it possible to rename a notarized ZIP package and not to loose the notarized status? One of our ZIP package contains resources and binaries which are code signed. The archive itself is accepted after submitting and uploading during the notarization process (online notarization). Unfortunately, the ZIP cannot be stapled (offline verification). So, is the filename part of the notarized ZIP package or can a ZIP package be renamed? Best regards, Stefan
