Error install in-house App on iPhone 16e
We are going to replace our iPhone SE to iPhone 16e. The issue is that we are unable to install an in-house app on the new iPhone 16e. The app works on the iPhone SE Both phones run on the same iOS version (18.5) Has anyone else experienced the same issue? I initially thought the iPhone 16e was the successor to the iPhone SE

Help Setting Up Apple MDM Vendor-Signed CSR and Push Certificate
Hello, I have an Apple Developer Enterprise account, and Apple Support has already enabled MDM for my account. I successfully downloaded and installed my MDM Vendor Certificate (it shows up in Keychain as MDM Vendor: [My Company Name] with its private key). Here’s what I’ve done so far: Exported the Vendor Certificate + private key as a .p12, then converted to .pem and .key using OpenSSL. Generated an unsigned CSR with CN=com.apple.mgmt.External. using OpenSSL. Attempted to sign the CSR using: my Vendor certificate the Vendor private key Apple Worldwide Developer Relations (WWDR) intermediate certificate OpenSSL smime -sign command with DER output Problem: Every time I try to upload the vendor-signed CSR to the Apple Push Certificates Portal, I get an error (CSR rejected). Sometimes OpenSSL even fails with “unable to load certificates” depending on how the WWDR certificate is included. My Questions: What is the correct OpenSSL command and certificate chain Apple expects for signing the CSR? Do I need to include any additional intermediates besides WWDR? Is there an official Apple reference example for generating the vendor-signed CSR that the Push Certificates Portal will accept? Any guidance from the community (or someone who has successfully done this end-to-end) would be greatly appreciated. Thank you, Sergio Sanchez

Wi-Fi Settings Lost During Native MDM Migration in iOS/macOS 26 Latest Beta
Hi Apple Community, At WWDC25, introduced a native device migration feature with iOS/macOS 26 and Apple Business Manager that promises seamless migration from one MDM to another without wiping devices or manual re-enrollment. That said, while testing this in iOS/macOS 26 beta, we ran into an issue: the Wi-Fi settings deployed by the old MDM aren’t retained during the migration. This means devices lose Wi-Fi connectivity partway through, and users have to manually reconnect before the migration to the new MDM can continue. This interrupts what should be a smooth, hands-off process. We wanted to ask if this is a known issue or limitation with the current beta? Are there any recommended ways to avoid losing Wi-Fi profiles during this migration window? Will this improve in future updates so that the Wi-Fi connection is preserved or seamlessly handed off to the new MDM? Any tips, workarounds, or official guidance Apple can share on best practices for handling Wi-Fi profiles during ABM-native device migrations would be hugely appreciated. Added Feedback with FeedBackAssistant ID : FB20150763 Thanks in advance.

Enterprise App Installation Fails on iOS 18.5 with Integrity Error
I am a developer distributing an enterprise app. Recently, some users have intermittently encountered an error message on iOS 18.5 stating: "Unable to install this app because its integrity could not be verified." While the issue could not be reproduced on iPhone 15 / iOS 18.5, we have received reports that it does occur on the following devices: iPhone 14 / iOS 18.5, iPhone 14 Pro / iOS 18.5, iPhone 14 Plus / iOS 18.5, iPhone 16 Pro Max / iOS 18.5, Are there any known issues or recommended solutions regarding this behavior? Thank you in advance for your assistance.

iCloud restore does not transfer application data when applied to new device
Hello, this may not be the correct place to ask this question so I apologize in advance if this is the case. We are currently having some issues when attempting to restore device back ups via iCloud that where previously enrolled to our MDM solution, as upon the restore no app data seems to be persisted over (we have tested restoring the backup on the same device and we have been able to have data persist between wipes) On the initial device we have ensured that the restrictions allowCloudKeychainSync allowManagedAppsCloudSync are set to true, and can see that the initial devices back up has the app data backed up, yet despite this data is not persisted when restoring from back up on a new device. On the device where the back up was initially done when restoring the applications are applied but indicated that they must be re-installed via our management console, once the app has been uninstalled and reinstalled the old data does show up, when applied to the new device our mdm solution pushes down the app.managed config but the device treats it as a new install. Could this possibly be due to us using Device Licensing when assigning apps? Or is it due to the intial device only performing a token update request when restoring and the new device going through the entire checkin proccess? Both devices are provisioned via DEP, and applications where assigned initially via VPP Any insight on this would be useful (For reference this is an MDM solution of our own making so we are attempting to sus out if there is a configuration issue we could be overlooking).

How to change the expiry date of existing iOS Distribution (In-House) Certificate
Hi Team, Could you please share how to change/extend the expiry date of the existing iOS Distribution (In-House) certificate? Since the membership renewal date is in March 2026 and the iOS distribution(In-House) certificate expiry date is in Feb 2026. We use to distribute the mobile apps using the product intunes (Company portal) and via direct download link. Please suggest since this certificate is used by multiple mobile apps by the users which can affect lot of iPhone users? Thank you in advance Deepak

Management of Camera File Formats
It seems like every time an IOS update is installed, the camera app file formats get reset to defaults. This setting is not available to manage at the MDM level. Many people need the the most compatible settings for the purpose of file sharing. So, now we have nearly 1,000 devices with a complete mix of photo and video formats. And IT has wasted MANY hours converting files for people. Feature Request: Please either stop resetting the camera app file formats or allow us to manage those settings at the MDM level. Respectfully, Robert

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

Providing client with IPA for internal distribution
Hey folks, I work as a software development consultant. We develop enterprise applications for our clients, and the apps we create are usually for internal use. We've ran into a bit of a conundrum with a client who doesn't have their own Apple Enterprise account, and neither do we as we don't meet the criteria, but they're wanting to distribute an application we've built for them via their own MDM software. We are not entirely sure how to provide them with a distribution ready .ipa file that isn't AdHoc and will be recognized as a secure app. We've looked into generating a Developer ID provisioning profile and accompanying cert, however we're running into a problem where the platform of our app (iOS) doesn't match the platform required by the Developer ID profile (macOS). I've also come across the idea of resigning an .ipa, but again, the client doesn't have a Apple Developer account and expects the working .ipa to be included in the service rendered. Any suggestions or advice or documentation around the subject would be greatly appreciated. Thanks, Ale

Serial number on supervised device
Hello world! First post here. Developing my first app. It primarily targets supervised and MDM managed devices. A few questions: For supervised devices, is serial number available? I want to get the number and use it for app auto activation Is MDM required for supervised devices? Or, as long as a device is enrolled through Apple Business Manager? Which capacity shall I request for the app? Thanks so much!

Rate limits for frequent iOS resets (EraseDevice) and activation processes?
Hello everyone, I am looking for technical clarification regarding potential rate limits when automating frequent iOS device resets. In my workflow, I need to reset test devices multiple times per day using the EraseDevice MDM command, often combined with the ReturnToService flag for automated setup. I understand that after a full reset, the device undertakes several critical steps to become operational again, including device activation, system app installation, MDM re-enrollment, and subsequent validation of developer certificates for internally distributed apps. Based on Apple’s documentation and my own observations, I am aware of the following domains being involved in these processes: Device Activation: albert.apple.com, gs.apple.com, captive.apple.com, humb.apple.com, static.ips.apple.com, sq-device.apple.com, tbsc.apple.com, time*.apple.com System App Installation: *.itunes.apple.com, *.apps.apple.com, *.mzstatic.com MDM Enrollment: Communication with Apple ADE servers followed by the MDM server. Developer Certificate Validation: ppq.apple.com, ocsp.apple.com, crl.apple.com My primary question is: Are there any rate limits imposed by Apple’s servers on these specific processes when performed frequently on the exact same device within a short timeframe (e.g., multiple times per day)? Specifically, could anyone provide information regarding potential limits for: Device activation requests? System app downloads post-activation? Automated Device Enrollment checks and subsequent MDM enrollments? Developer certificate validation requests? Additionally, is the list of domains above comprehensive for these processes, or are there other key endpoints involved that I should be aware of regarding potential rate limiting? Understanding these limitations is crucial for ensuring the reliability of automated device management workflows. Thank you for any insights!

Return to Service with App Preservation issue
We are implementing the Return to Service (RTS) with App Preservation flow. During testing, we were able to successfully fetch the Bootstrap Token as part of the ADE enrollment process. However, when attempting to initiate the Return to Service command with App Preservation enabled, the following error was returned: [ { "ErrorCode": 12089, "ErrorDomain": "MDMErrorDomain", "LocalizedDescription": "Could not erase device.", "USEnglishDescription": "Could not erase device." }, { "ErrorCode": 66002, "ErrorDomain": "MDMBootstrapTokenErrorDomain", "LocalizedDescription": "Failed to generate LAContext for bootstrap token", "USEnglishDescription": "Failed to generate LAContext for bootstrap token" } ] Below is the sample request (with dummy data).

DMM App Managed doesn't allow for reinstalls or respects version element
Hello, this may not be the correct place to ask this question so I apologize in advance if this is the case. I am currently running into two specifc issues while continuing to implement the app.managed configuration which are quite frustrating and I will detail them below Unlike MDM where an application could be "reinstalled", by sending an install application command down for the same app DM does not have a similar mechanism which causes some issues as (while inconsistent) devices do not always respect the configuration sent down, and will not begin downloading VPP applications. They can be seen in the configuration when checking under VPN & Device Management but they do not return on a status report, alternatively and app will "install" but will have a cloud symbol next to it requiring a download (which I believe would be impossible on supervised devices without apple accounts/have restricted apple accounts associated to them). These apps are also reported incorrectly, as they return a managed response while being inaccessible. Both of these issues are solved by removing and reinstall applications (occasionally). Is there any easier way to trigger a re-install or is this the only way to trigger this? The Version element that can be optionally sent down does not seem to work (or if it does, does so inconsistently). A device will very happily download the application initially with the version element present, though when we detect an updated external ID from the VPP program and send down an updated configuration devices behave unexpectedly. Some have ignored it, some have responded back that a download has begun (with no download taking place and the application clearly still being the initial installed version as can be see in the apps page) or it just works, but there is not consistency. I realize a new UpdateBehavior object has been added to possibly handle this, but it is only supported in iOS 26 and above and there are plenty of people who do not have phones that can upgrade that far. Are there alternative ways to enforce an application update other than uninstalling and reinstalling the application without the version (or will sending down a config without a version after one was originally pinned force it to update to latest?) Kind Regards

Activation Lock Bypass Code
We are having issues working with bypass codes the server creates when initiating Activation Lock through MDM. We are able to use the device-generated bypass codes without issue. When using the end point to request activation lock as specified in https://developer.apple.com/documentation/devicemanagement/creating-and-using-bypass-codes/ we get a 200 response. But when using the endpoint to bypass the activation lock, we get a 404 response. If we try to manually input the activation lock bypass code, it also does not work. Both of these methods work with the device-generated bypass codes. Just to clarify when testing the server generated codes, we ensured that we did not test the device-generated codes. All of this was tested on iOS devices. Created feedback ticket FB21365819 with device specific details.

I am currently running into two specifc issues while continuing to implement the app.managed configuration which are quite frustrating and I will detail them below Unlike MDM where an application could be "reinstalled", by sending an install application command down for the same app DM does not have a similar mechanism which causes some issues as (while inconsistent) devices do not always respect the configuration sent down, and will not begin downloading VPP applications. They can be seen in the configuration when checking under VPN & Device Management but they do not return on a status report, alternatively and app will "install" but will have a cloud symbol next to it requiring a download (which I believe would be impossible on supervised devices without apple accounts/have restricted apple accounts associated to them). These apps are also reported incorrectly, as they return a managed response while being inaccessible. Both of these issues are solved by removing and reinstall applications (occasionally). Is there any easier way to trigger a re-install or is this the only way to trigger this? The Version element that can be optionally sent down does not seem to work (or if it does, does so inconsistently). A device will very happily download the application initially with the version element present, though when we detect an updated external ID from the VPP program and send down an updated configuration devices behave unexpectedly. Some have ignored it, some have responded back that a download has begun (with no download taking place and the application clearly still being the initial installed version as can be see in the apps page) or it just works, but there is not consistency. I realize a new UpdateBehavior object has been added to possibly handle this, but it is only supported in iOS 26 and above and there are plenty of people who do not have phones that can upgrade that far. Are there alternative ways to enforce an application update other than uninstalling and reinstalling the application without the version (or will sending down a config without a version after one was originally pinned force it to update to latest?) Kind Regards

Activation Lock Bypass Code
We are having issues working with bypass codes the server creates when initiating Activation Lock through MDM. We are able to use the device-generated bypass codes without issue. When using the end point to request activation lock as specified in https://developer.apple.com/documentation/devicemanagement/creating-and-using-bypass-codes/ we get a 200 response. But when using the endpoint to bypass the activation lock, we get a 404 response. If we try to manually input the activation lock bypass code, it also does not work. Both of these methods work with the device-generated bypass codes. Just to clarify when testing the server generated codes, we ensured that we did not test the device-generated codes. All of this was tested on iOS devices. Created feedback ticket FB21365819 with device specific details.

Configure a per-app VPN aways on (kill switch)
Hi guys, I need to configure a VPN to work only for specific apps. I already have a supervised iPhone, and I’ve successfully configured the VPN, but right now it applies to the whole phone. I need it to work just for some apps. I tried using both Apple Configurator and iMazing, but I can’t find this option there.
