iOS 26 devices in Single App Mode stuck on lock screen
On iOS 26, if in "Single App Mode", the device gets stuck on the lock screen. Devices are configured in SAM (kiosk mode), without a PIN requirement. Since updating to iPadOS 26, every single device that locks (goes to sleep) becomes completely unresponsive at the lock screen. Touch input does not work. The only way to regain access is to reboot the device, which will boot to the SAM app, but then lock again if it goes to sleep. Related discussion in the public forums.

External UUID
Hello, I am Sergio Sánchez, administrator of NumbuX. We are developing our own MDM. We are already granted as a MDM Vendor. We need to issue the APNs certificate for our MDM for the first time in the Push Certificate portal (identity.apple.com). We are having the error: “invalid signing request” when we upload the signed CSR to identity.apple.com. That is because we do not have the External UUID. Could you please let us know what is our External UUID? Without that, we cannot upload it successfully. We have already compared different signed CSR from other MDM Vendors and all have included the External UUID in the CSR. Please, do not send links, there is not way for us to know our External UUID because it is the first time that we try to issue this APNs. After the first time, we do not need your assitance. Please, let us know our External UUID. Thank you. Kind regards.

MDM Profile Installation Issue on iPhone 17 - Suspected Parameter Transmission Error
Issue Description: We are experiencing MDM profile installation failures specifically on iPhone 17 devices. After extensive testing and comparison between affected and working devices, we suspect this appears to be a parameter transmission error rather than device settings. Technical Analysis: Device Settings Comparison: No differences found between problematic and working devices in system settings, indicating this is not a configuration issue. Suspected Parameter Transmission Error: • Device model information appears to be restricted or blocked during profile download • User ID and phone number parameters are not being transmitted to the server • Installation logs show missing login ID and phone number entries Symptoms: • During MDM profile installation, the "Apps & Restrictions" section that should appear is missing • Profile download parameters are suspected to not be properly transmitted to the server • Installation process fails at the profile configuration stage Critical Finding: When we cloned a previously working device to create a problematic device configuration, the cloned device also began experiencing the same installation failures. This strongly suggests the issue is related to device-specific parameters or identifiers. Additional Information: We continue to receive reports of this issue from our iPhone 17 users, and these reports are occurring across various iOS versions. Request for Assistance: Has anyone encountered similar MDM profile installation issues on iPhone 17? Are there known limitations or changes in how device parameters are transmitted during MDM enrollment on this model? Any guidance on debugging parameter transmission or known workarounds would be greatly appreciated.

Supervised devices show wifi setup screen on restart
When an iOS 26.0 device is prepared in supervised mode, wifi connection screen is showing when the device is restarted. This wifi connect appears always on restart. I have tried using Apple Configurator GUI and Command line (cfgutil) command. In both cases, The behavior Wifi screen is showing up on restart for supervised mode. Cfgutil command: cfgutil -C {Certificate} -K {Key} prepare --supervised --name {NAME} --host-cert {Certificate} --skip-all Note: In non-supervised mode and other iOS, the wifi screen is not showing. Apple Configurator version: 2.18 iOS version: 26.0 Device model: iPhone 11 and above. Anyone else facing this issue? Any help is super appreciated.

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.

Device enrollment to ABM failing with timeout during setup
Hello, I’m facing an issue while trying to add iOS devices to Apple Business Manager (ABM) using Apple Configurator during enrollment. When going through the setup process, the device fails to complete enrollment and times out. I’ve tried it multiple times. The device does appear in ABM during the process and I am able to assign it to different MDM servers but since the setup times out and fails, the device is automatically released. I have tried this with multiple iOS devices and it times out on every single one of them. Steps attempted: Factory reset and re-enrollment of the device Ensured network connectivity is stable and tested on multiple Wi-Fi networks Tried the following process using Apple Configurator on Mac (wired): Created a Wi-Fi profile in Configurator Connected the iPhone via cable and used Prepare (manual configuration) Used the “MDM server” placeholder and trusted anchors (as recommended) Linked the device to the ABM organization Skipped Setup Assistant steps Attached the Wi-Fi profile, then prepared and wiped the device Verified that the device should appear in ABM Attempted to assign the device to my MDM in ABM Despite these checks, the enrollment process times out. I’m attaching a screenshot of the error for reference. Could someone advise what might be causing this timeout or how I can further troubleshoot this? Any guidance would be greatly appreciated. Thanks in advance.

ABM Sync Fails with “Terms and Conditions Not Signed” Error Despite Acceptance
We are experiencing an issue with Apple Business Manager (ABM) synchronization that is blocking our device management workflow. Issue Description: During the ABM sync process in our MDM, we receive the error: "ABM Terms and Conditions not signed." What We’ve Checked: Logged into the ABM portal as the Administrator and confirmed that the latest Terms and Conditions. Attempted to renew the ABM token on our existing server, but the same error message continues to appear in MDM. Tried creating a brand new ABM server integration, which also fails with the same error. We checked with our MDM provider and they shared the logs, response received from ABM. It says T_C_NOT_SIGNED. But we have already accepted all the new Terms in ABM. We would appreciate any help in resolving this issue or guidance on what steps to take next.

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

Disable Fast User Switching in Control Center
We've disabled FUS through a config profile, but users can still access FUS by enabling the MenuBar/Control Center icons. My org would like to prevent access to FUS so I've created a config profile. But the profile doesn't seem to work.

Certificado APN para MDM por primera vez
Nuestra cuenta está aprobada como MDM Vendor y necesitamos emitir por primera vez el certificado APNs para MDM en el portal de Push Certificates. Procedimiento seguido Primero hemos descargado desde nuestra cuenta de Apple Developer el certificado de MDM Vendor y lo hemos instalado en el ordenador. Esto lo hemos hecho para que, al lanzar la instrucción de OpenSSL, se pueda utilizar el UUID gestionado por Apple y así generar el CSR de forma correcta. La instrucción que estamos ejecutando es la siguiente: openssl req -new -newkey rsa:2048 -nodes -keyout mdm_private.key -out mdm.csr -subj "/O=Numbux/OU=MDM/CN=com.apple.mgmt.External." El CSR resultante es puro (no está firmado ni empaquetado) y está generado con RSA 2048 y SHA256. Sin embargo, al subirlo al portal de Push Certificates, seguimos recibiendo el error “invalid signing request”. Solicitud Dado que es nuestra primera emisión, entendemos que necesitamos el External UUID asignado por Apple a nuestra organización, porque veo que el problema se deriva de una incorrecto UUID que se está generando en el comando OpenSSL. ¿Podríais confirmarnos cuál es ese valor para poder completar el CSR y así emitir correctamente el certificado APNs MDM? He llamado a los números 900 812 703 y al 900 812 468 y he escrito al soporte de developer. NADIE ES CAPAZ DE DARMELO. Sin el external UUID no puedo crear el APN para mi MDM. Alguien me puede ayudar? No me mandeis links ni posibles números que llamar porque ya lo he hecho.

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!

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

App whitelist profile working on supervised iPhone, but not on paired Watch
Hello, I’ve run into an issue with a configuration profile on my supervised iPhone. I’m wondering if anyone here might be able to help? The profile contains the allowListedAppBundleIDs key within the restrictions payload. My Apple Watch is paired with the iPhone. The iPhone was supervised manually with Apple Configurator, hence the Apple Watch has not been directly supervised itself. The profile works completely as expected when installed on the phone. As soon as the profile is installed on the iPhone, I can witness the apps on the Apple Watch rearrange themselves as some apps are hidden. So clearly the profile is applying its restrictions to the Apple Watch to some degree. My issue however is that apps listed in the whitelist are hidden from the Watch. The apps that are missing from my Watch are Walkie Talkie, Find My Items, Find My Friends, Messages, Alarm, Remote, Now Playing, Sleep, Meditation and Heart Rate. This is despite the following bundle IDs being listed in the whitelist array: com.apple.findmy.findpeople, com.apple.findmy.finddevices, com.apple.HeartRate, com.apple.SessionTrackerApp, com.apple.NanoWorldClock, com.apple.findmy.finditems, com.apple.Mind, com.apple.NanoOxygenSaturation, com.apple.watchmemojieditor com.apple.NanoSleep com.apple.NanoNowPlaying com.apple.noise com.apple.tincan com.apple.NanoRemote com.apple.NanoAlarm com.apple.private.NanoTimer com.apple.NanoStopwatch I’ve done some testing, but not sure what I’ve found really. I’ve so far identified 3 scenarios. Scenario 1: I have the whitelist profile installed on the iPhone. I download an app that appears in the whitelist from my watch (or at least its iPhone version does). The apps show up on the iPhone automatically and can be launched there. These apps cannot be launched on the watch. Scenario 2: I downloaded a few apps to my watch, that didn’t automatically install on my iPhone at the same time. They were on the whitelist. These ones couldn’t be launched from my Watch. I then downloaded them to the iPhone and they could be launched there (since they were on the whitelist). Scenario 3: A couple of 3rd party apps on the whitelist could be downloaded and launched from the watch with the whitelist installed. It seems as though there are different kinds of Apple Watch app and this is what I’ve read elsewhere. First of all there are Watch-only apps, which do not automatically install a companion iPhone app. Secondly there are companion apps, which when installed from the Watch App Store download their companion app to the iPhone in the background. Someone please correct me - I’m bound to be overlooking something here. So maybe the apps that when installed from Watch automatically install on iPhone and can only be launched from the iPhone have a separate bundle ID for their Watch app which I haven’t included? Apps that are on the whitelist AND do not automatically install an iPhone app AND can be launched from the Watch, include: solstice What3words So maybe these do not need a companion app, but have the same Bundle ID as their iPhone app? However, I’m still not sure why many stock Apple Watch apps are missing from the Watch…. The most obvious answer is that I’ve got their Bundle IDs wrong, but I don’t think I have given I extracted the bundle IDs from the App Store pages of the Apple WatchOS apps. I noticed at this Apple Support page (https://support.apple.com/en-gb/guide/deployment/dep34c5cd30f/1/web/1.0) that there is no mention of whitelisting or blacklisting apps on WatchOS using MDM, yet something definitely happens on the watch when the configuration profile is installed on the iPhone. Furthermore, if I tap on a configuration profile, which comprises a blacklist, on my iPhone it will ask me if I want to install it on the iPhone or Watch. The same pop-up question doesn’t happen when the profile contains a whitelist. All this to say, I’m massively confused as to why I can’t get this working. I’d really appreciate anyone’s advice which is bound to be expert. Thank you

In the iOS 26 beta, enterprise Apps installed via MDM cannot be run
I am a developer working on iOS apps. I would like to report an issue occurring in iOS 26 beta 2. Our company has Enterprise account, and we are developing apps. When we distribute these apps, and install them on a device running iOS 26 beta2, apps install successfully, but apps crashed immediately after being launched. MDM Install Application When I install the app via Xcode and trust it, apps will run. Launchd job spawn failed This issue does not occur on versions prior to iOS 26. I would like to know if this is a problem that will be resolved in future updates, or if it is a policy change.

iOS 18 - Unable to receive files using AirDrop when "allowListedAppBundleIDs" restriction key is used
On a supervised device running iOS 18 without any AirDrop restrictions applied, when a profile with allowListedAppBundleIDs restriction key is installed, the AirDrop sound plays. But still the accept prompt does not appear, making it impossible to accept files. The prompt works as expected on iOS 18 devices to which the allowListedAppBundleIDs restriction is not installed. This issue occurs only on supervised iOS 18 devices to which the allowListedAppBundleIDs restriction is being applied. Device must be in iOS 18 version > Install the (allowListedAppBundleIDs restriction) profile with the device > Try to AirDrop files to the managed device. The expected result is that the accept prompt must pop up but it does not appear. This issue is occurring irrespective of any Whitelisted bundle ID being added to the allowListedAppBundleIDs restriction profile. Have attached a few Whitelisted bundle ID here com.talentlms.talentlms.ios.beta, com.maxaccel.safetrack, com.manageengine.mdm.iosagent, com.apple.weather, com.apple.mobilenotes, gov.dot.phmsa.erg2, com.apple.calculator, com.manageengine.mdm.iosagent, com.apple.webapp, com.apple.CoreCDPUI.localSecretPrompt etc. Have raised a Feedback request (FB15709399) with sysdiagnose logs and a short video on the issue.

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).
