forum-post-v2-evidence.log MCRestrictionsPayload (allowListedAppBundleIDs) breaks Apple Watch app enumeration — nanotimekitcompaniond reports "Missing .app from directory: /Watch/" Summary Installing a Configuration Profile with com.apple.applicationaccess payload containing allowListedAppBundleIDs causes native Apple Watch apps to disappear from the paired Watch — even when their bundle IDs are explicitly in the whitelist. Log analysis shows this is not a bundle ID matching problem: nanotimekitcompaniond on the iPhone fails to enumerate the <companion>.app/Watch/ subdirectories where native watchOS app stubs live. Follow-up to https://developer.apple.com/forums/thread/745585 — community-confirmed but received no official response. Environment iPhone 16 (iPhone17,3), iOS 26.4.2 (23E261), supervised Apple Watch paired via Bridge.app Profile installed locally via Apple Configurator (no MDM server required) Smoking gun Within ~5 seconds of profile install, two processes (nanotimekitcompaniond and NTKFaceSnapshotService) log identical errors for eight companion-app paths: nanotimekitcompaniond[1498] <Error>: Missing .app from directory: file:///Applications/MobilePhone.app/Watch/ nanotimekitcompaniond[1498] <Error>: Missing .app from directory: .../Calculator.app/Watch/ nanotimekitcompaniond[1498] <Error>: Missing .app from directory: .../Bridge.app/Watch/ nanotimekitcompaniond[1498] <Error>: Missing .app from directory: .../MobileTimer.app/Watch/ nanotimekitcompaniond[1498] <Error>: Missing .app from directory: .../Camera.app/Watch/ nanotimekitcompaniond[1498] <Error>: Missing .app from directory: .../VoiceMemos.app/Watch/ nanotimekitcompaniond[1498] <Error>: Missing .app from directory: .../MobileMail.app/Watch/ nanotimekitcompaniond[1498] <Error>: Missing .app from directory: .../FindMy.app/Watch/ NTKFaceSnapshotService[3758] <Error>: Missing .app from directory: <same 8 paths> The Watch's app icons and face complications both go through these processes, which explains the symptoms users see. iOS itself flags the payload as Watch-incompatible — but applies it anyway profiled[179] <Notice>: Payload class MCRestrictionsPayload (com.apple.applicationaccess) is not supported on any Watch version profiled[179] <Notice>: Payload class MCRestrictionsPayload (com.apple.applicationaccess) is not available on HomePod profiled[179] <Notice>: Beginning profile installation... profiled[179] <Notice>: Profile "...v2..." installed. So profiled knows the payload doesn't target watchOS — yet its side effects clearly manifest there. Tests performed Test Bundle IDs in whitelist Result v1 249 (every installed iOS app: Apple + 3rd party) Walkie-Talkie, Messages, Find My + more disappear from Watch v2 295 (v1 + every Apple extension/Nano* daemon seen in syslog: *.MessagesActionExtension, *.FindMyNotifications*Extension, *.FindMyWidget*, com.apple.NanoBackup, com.apple.NanoMusicSync, com.apple.NanoPreferencesSync, com.apple.NanoTimeKit.face, com.apple.NanoUniverse.AegirProxyApp, com.apple.tursd, com.apple.FaceTime.FTConversationService, com.apple.Bridge.GreenfieldThumbnailExtension, etc.) Identical Missing-.app errors. Same apps disappear. Conclusion: this is not a bundle ID matching issue — adding more IDs doesn't help. The system fails to enumerate <companion-iOS-app>.app/Watch/ regardless of whitelist contents. Many users in my prior thread reported trying 100+ bundle ID combinations without success; this evidence explains why. Reproduction (no MDM required) Pair Apple Watch with iPhone normally. Generate a Configuration Profile with com.apple.applicationaccess + any non-empty allowListedAppBundleIDs array. Install via Apple Configurator's cfgutil install-profile, or AirDrop + Settings → Install. Within ~5 s, nanotimekitcompaniond errors appear (visible via idevicesyslog). Native Watch apps backed by an iOS companion stub disappear from the Watch's app grid and from face complications. Hypothesis MCRestrictionsPayload applies an enumeration filter that does not descend into .app/Watch/ subdirectories when computing visible apps. nanotimekitcompaniond consequently sees those directories as missing, the Watch's Carousel (SpringBoard equivalent) hides the apps, and NTKFaceSnapshotService can't load corresponding complications. Because profiled itself logs the payload as "not supported on any Watch version", this appears to be unintended bleed-through. Questions for Apple Is MCRestrictionsPayload / allowListedAppBundleIDs officially supposed to affect Apple Watch apps? profiled says no. Is there an undocumented bundle ID pattern (e.g. <companion>.watchapp, or a Bridge.app/Watch/ prefix) that needs whitelisting to keep native Watch apps visible? Is the recommended workaround to use blacklistedAppBundleIDs instead? Should the enumeration error (Missing .app from directory: .../Watch/) be tracked as a separate watchOS framework bug? Artifacts Curated evidence log with timestamps, profile installer events, and the eight Missing-.app errors is attached as forum-post-v2-evidence.log. Full idevicesyslog captures (multiple install/remove cycles, ~2M log lines) and the .mobileconfig files are available on request. Thanks — looking forward to guidance.

Summary: When applying a configuration profile that uses allowListedAppBundleIDs to permit a defined set of apps, essential Apple Watch apps are unexpectedly removed from the paired Watch — even though their associated iPhone bundle IDs are explicitly included. This issue occurs with a minimal profile, and has been consistently reproducible on the latest versions of iOS and watchOS. Impact: This behavior severely limits the use of Apple Watch in managed environments (e.g., education, family management, accessibility contexts), where allowlisting is a key control mechanism. It also suggests either: Undocumented internal dependencies between iOS and watchOS apps, or A possible regression in how allowlists interact with Watch integration. Steps to Reproduce: Create a configuration profile with a Restrictions payload containing only the allowListedAppBundleIDs key. Allow a broad list of essential system apps, including all known Apple Watch-related bundle IDs: com.apple.NanoAlarm com.apple.NanoNowPlaying com.apple.NanoOxygenSaturation com.apple.NanoRegistry com.apple.NanoRemote com.apple.NanoSleep com.apple.NanoStopwatch com.apple.NanoWorldClock (All the bundles can be seen in the Attached profile) Install the profile on a supervised or non-supervised iPhone paired with an Apple Watch. Restart both devices. Observe that several core Watch apps (e.g. Heart Rate, Activity, Workout) are missing from the Watch. Expected Behavior: All apps explicitly included in the allowlist should function normally. System apps — especially those tied to hardware like Apple Watch — should remain accessible unless explicitly excluded. Actual Behavior: Multiple Apple Watch system apps are removed or hidden, despite their iPhone bundle IDs being listed in the allowlist. Test Environment: iPhone running iOS 18 Apple Watch running watchOS 11 Profile includes only the allowListedAppBundleIDs key Issue confirmed on fresh devices with no third-party apps Request for Apple Engineering: Please confirm whether additional internal or undocumented bundle IDs are required to preserve Apple Watch functionality when allowlisting apps. If this behavior is unintended, please treat this as a regression or bug affecting key system components. If intentional, please provide formal documentation listing all required bundle IDs for preserving Watch support with allowlisting enabled.

I know Apple Engineers are busy, It’s great that non-Apple Engineers offer advice and assistance, but I kind of thought there’d be at least a reply from an Apple Engineer on MDM issues? I have posted about apple watch mdm issues and have got none responses

I am experiencing difficulties in fully integrating my Apple Watch with a supervised iPhone under MDM control. While I have successfully paired the watch with the iPhone, I am facing issues with some apps not syncing or appearing on the Apple Watch. This issue persists despite having allowed their bundle IDs in the MDM’s whitelist. Could anyone provide guidance on which specific Apple bundle ID is crucial for maintaining the connectivity and functionality between the iPhone and the Apple Watch? Understanding this would help in ensuring that the necessary bundle ID is whitelisted in the MDM settings, thus resolving the app visibility and functionality issues on the Apple Watch.

I've encountered an issue while reviewing logs from my device and hope someone here can shed some light on it. In the process of diagnosing an application behavior, I noticed that some entries in my logs are marked as , specifically next to bundle IDs, which makes it challenging to understand which app or process is involved. Here are the relevant log entries: Feb 21 17:40:53 vCw-2 suggestd(CoreSuggestionsInternals)[30399] &lt;Notice&gt;: SGDSuggestManager: realtimeSuggestionsForMailOrMessageWithHash: com.apple.MobileSMS : &lt;private&gt; Feb 21 17:40:53 vCw-2 suggestd(CoreSuggestionsInternals)[30399] &lt;Notice&gt;: SGDSuggestManager: realtimeSuggestionsForMailOrMessageWithHash: &lt;private&gt;: results: (null) Feb 21 17:40:53 vCw-2 suggestd(CoreSuggestionsInternals)[30399] &lt;Notice&gt;: SGDSuggestManager: realtimeSuggestionsForMailOrMessageWithHash: com.apple.MobileSMS : &lt;private&gt; Feb 21 17:40:53 vCw-2 suggestd(CoreSuggestionsInternals)[30399] &lt;Notice&gt;: SGDSuggestManager: starting dissection. The identification of this hidden bundle ID is essential for allowing the specific iMessage Business Chat feature to function as intended in our MDM-managed devices. Does anyone have insights into why the bundle ID might be hidden or how to uncover it? Are there tools or methods available that could help me identify this bundle ID for MDM whitelist configuration purposes? I appreciate any guidance or recommendations you can provide. Thank you for your time and assistance.

I need help pairing apple watch to Supervised iPhone with MDM. Need to know which apple bundle id is the one resposable for the connection. By now the watch does pair with the iPhone but some of the apps dont appear on the apple watch though I've already allowed those bundles in my MDM. Thank you!
