Issue with MDM InstallApplication manifest retrieval with mutual TLS
We have a development where we are MDM managing iOS devices and attempting to enforce mutual TLS for all interactions with the MDM. We are DEP provisionng an enrolment profile that utilises an ACME hardware attested Device Identity Certificate. All interactions with the MDM endpoints are correctly utilising the ACME certificate for the client mutual TLS handshake. The certificate has Client Authentication Extended Key Usage. Behind the same API gateway and on the same SNI we are also serving paths to Enterprise application manifests and IPAs. We can see from the phone log and from packet traces the iOS device doesn't offer the Device Identity Certificate for client authentication when retrieving these URLs. We have also tried adding non ACME client certificates from the root trusted by the server to the initial profile with exactly the same outcome. If we temporarily disable the mutualTLS we can see that the request for the manifest has a userAgent of "com.apple.appstored/1.0 iOS/18.2 model/iPhone17,3 hwp/t8140 build/22C5125e (6; dt:329) AMS/1" which is not the same as the mdm interactions. Is it actually possible to achieve mutualTLS to authenticate these downloads or is a different solution required ? Any advice greatly appreciated.

Geolocation Manager without function?
Hello, I write my bachelor-thesis about geolocation data on an iPhone. I write a small app to get the actual coordinates and saved into a sqlite database. so far so far. Now I have a GPS-generator from R&S to simulate gps-data and satellites. I can simulate 6 satellites parallel to my "fake" geolocation. I write the app also on an Android -smartphone, this Android can display the Satellites-ID and the "fake" geolocation..thats fine for my thesis. But my iPhone would not display anything I this setup? During outside the app would be deliver the actual coordinate, but with the signal.genarator I can't get coordinates. I try GPS, Glosnass, Galileo and Beidoo but nothing happens on my iPhone 12mini. The IOS is 18.1 and I use the core Location api. Has anybody some ideas for me and my thesis?

allowWebDistributionAppInstallation and forcePreserveESIMOnErase require supervision discrepantly with documentation
We provide a MDM product. In our product, payloads and properties which require supervision display those requirements. Two properties forcePreserveESIMOnErase and allowWebDistributionAppInstallation of the restriction payload don’t require a supervised device according to the descriptions in Apple Developer Documentation. However, in our observation, those properties seem to require it. Are those OS bugs or documentation errors? (In which category should I submit a feedback?) Steps to reproduce Prepare a supervised device (I used an iPhone 12 mini with iOS 18.1) and a configuration profile contains the following restrictions: <!-- Does not require a supervised device --> <key>allowDiagnosticSubmission</key> <false/> <!-- Requires a supervised device --> <key>allowESIMModification</key> <false/> <!-- Does not require a supervised device according to its description --> <key>allowWebDistributionAppInstallation</key> <false/> <!-- Does not require a supervised device according to its description --> <key>forcePreserveESIMOnErase</key> <true/> Then, Install the profile with Apple Configurator. Confirm 4 restrictions are shown in Settings > General > VPN & Device Management > PayloadDisplayName > Restrictions. Punch Settings > General > Transfer or Reset iPhone > Erase All Content and Settings, to unsupervise. Install the profile with Apple Configurator. It cannot be installed automatically because the device was not supervised. Manually install the downloaded profile. Check Settings > General > VPN & Device Management > PayloadDisplayName > Restrictions. Expected results 3 restrictions—allowDiagnosticSubmission, allowWebDistributionAppInstallation and forcePreserveESIMOnErase—are shown. Actual results Only one restriction—allowDiagnosticSubmission—is shown. Appendix: Restriction keys and their restricted message shown in Settings allowESIMModification: eSIM modification not allowed forcePreserveESIMOnErase: Preserve eSIM on erase enforced allowWebDistributionAppInstallation: Web app distribution not allowed allowDiagnosticSubmission: Diagnostic submission not allowed

Do MDM Certificates work after Apple Developer Account Expiry? Do they continue to work after renewal?
I have an issue with my MDM setup. The Push notification that installs and updates configuration profile in the device is no longer working. It was working before Apple developer account got expired we renewed our apple developer account and then retried and we got the device enrollment working just fine. Now when we are updating configuration profile and MDM server is supposed to notify the device using push notification, this is the part where its not working. Are the certs faulty now since the account was expired? Would just renewal of the Push cert work? Will I have to setup the certs all over again? Any help is appreciated. Thanks in advance.

Question on using Apple TTS voice (commercial use and license)
Apple provides a function to create TTS voice as a file in TTS. (AVSpeechUtterance/AVSpeechSynthesizer) Or, if the user records the video of TTS playback and uses that video I wonder what the scope of use is if I use this TTS voice to make YouTube, TikTok, or commercial videos. Is it impossible to use it commercially at all? Can I use it commercially with the source indicated? Can I use it commercially without a separate source indication? Is there a difference in commercial use license between Siri voices and regular TTS voices?

Content-filter overwritten by a third-party content-filter
I have an MDM supervised device with an installed managed app, that activates a content-filter solution to filter traffic system-wide. Is it possible in any way for the user to install a third party content-filter app that would somehow overtake the control of content filtering from my app? I'm asking this because I've tested such a case with my another test content-filter solution and it takes control over content filtering from my content-filter – I think this is possible only because my device is in developer mode, but I'm not entirely sure, and I need a confirmation that it would not be possible to happen in an end used environment.

Restrict user from potentially editing a supervised device through Apple Configurator
Is there a way to restrict an end user from potentially editing a supervised device through Apple Configurator? It seems that Apple Configurator allows to make undesirable changes to a supervised device, like removing profiles, which would in turn be detrimental to the intended experience on the device, if a user would actually be able to perform such changes.

Can mdm contain configurations that are not supported by the system version?
Hi,team: I need to distribute an mdm configuration file containing the "ServiceManagementManagedLoginItems" service to a large number of company-supervised computers, where com.apple.servicemanagement only supports macOS 13.0+. However, I cannot effectively distinguish whether the device system where the mdm configuration file needs to be installed is greater than 13. Can I directly install the mdm configuration file on all devices? Will installing the mdm configuration file on devices less than 13 have any impact on the system or other configuration items in mdm? The description link of ServiceManagementManagedLoginItems is: https://developer.apple.com/documentation/devicemanagement/servicemanagementmanagedloginitems

Enterprise App Crashes on Launch on iOS 18.3.2
We have an office application used internally within our enterprise. The Provisioning Profiles (PP) for the app were about to expire, so we updated the PP and released a new version. However, we've encountered an issue where some users did not update their phones in time. After the app expired, they found it unusable and downloaded the new version, but the newly downloaded app also crashes on launch. Restarting the phone does not resolve the issue, and this primarily occurs on iOS 18.3.2. What could be the cause of this problem, and how should we address it?

When did the phonenumber item among the information that can be obtained by the command 'DeviceInformation Command.command.Queries' stop?
Hello ! Currently, we have customers who use about 5,000 devices. In the case of ios26, the phone number is not acquired overall, and 18.x, 17.x, and 16.x are all acquired in half and not acquired in half. https://developer.apple.com/documentation/devicemanagement/deviceinformationcommand/command-data.dictionary/queries-data.dictionary It seems that it is the right behavior not to acquire it on the specification sheet. However, I wonder when it became impossible to acquire. (There are devices that can be acquired and devices that can't be acquired in the same os version.) Will the devices that are being acquired be blocked someday? When it was developed in 2019, it was in a state that could be acquired in full. I would also like to ask if there is an alternative way to get your phone number. Thank you.

Server docking subscription and automatic subscription interface
Hello: The App Store provides https://developer.apple.com/help/app-store-connect/configure-in-app-purchase-settings/enter-server-urls-for-app-store-server-notifications When the server interfaces with this interface, it is found that the specific user account cannot be found. How should I know which user initiated the subscription, or which user automatically subscribed during automatic renewal? Do you have a user account or ID? I hope to receive your complete answer as soon as possible. Best wishes.

Unexpected Removal of Apple Watch Apps When Using allowListedAppBundleIDs in iOS Configuration Profile
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. Attachment: .mobileconfig profile demonstrating the issue (clean, minimal, reproducible) Attached test profile = https://drive.google.com/file/d/12YknGWuo1bDG-bmzPi0T41H6uHrhDmdR/view?usp=sharing
