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. Anyone have any ideas what I'm missing, or is this an OS bug? <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>PayloadDisplayName</key> <string>macOS - Tahoe - Disable Fast User Switching Control Center</string> <key>PayloadIdentifier</key> <string>com.myorg.fast-user-switching</string> <key>PayloadType</key> <string>Configuration</string> <key>PayloadScope</key> <string>System</string> <key>PayloadUUID</key> <string>f1a2b3c4-d5e6-7890-abcd-ef1234567890</string> <key>PayloadVersion</key> <integer>1</integer> <key>TargetDevmyorgType</key> <integer>5</integer> <key>PayloadContent</key> <array> <dict> <key>PayloadType</key> <string>com.apple.controlcenter</string> <key>PayloadVersion</key> <integer>1</integer> <key>PayloadIdentifier</key> <string>com.apple.controlcenter.57EBEF9E-E568-411E-AE27-500AD98C94F4</string> <key>PayloadUUID</key> <string>f1a2b3c4-d5e6-7890-abcd-ef1234567890</string> <key>UserSwitcher</key> <integer>8</integer> </dict> <dict> <key>PayloadType</key> <string>.GlobalPreferences</string> <key>PayloadVersion</key> <integer>1</integer> <key>PayloadIdentifier</key> <string>.GlobalPreferences.71DE1486-60BC-4CB9-890D-AD50A772890D</string> <key>PayloadUUID</key> <string>c5234012-e0sw-2066-6fl8-3bd5p8125op7</string> <key>MultipleSessionEnabled</key> false/> </dict> </array> </dict> </plist>

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

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.

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.

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.

Hi there, We’re testing Declarative Device Management (DDM) for VPP app management and followed the latest declaration template here: https://github.com/apple/device-management/blob/release/declarative/declarations/configurations/app.managed.yaml Our goal is to enable VPP auto-updates via the declaration. The payload we’re using looks like this: "AppStoreID": "1231325957", "InstallBehavior": "{\"Install\": \"Required\", \"License\": {\"Assignment\": \"Device\"}}", "UpdateBehavior": "{\"AutomaticAppUpdates\": \"AlwaysOn\"}" } What we’re seeing Device A (no Apple ID signed into App Store): User can manually update the VPP app with the above declaration in place. ( The same user cannot update the app if UpdateBehavior is not in the declaration payload. Device B (Apple ID signed into App Store, and the same Apple ID doesn't have the above app purchased): User cannot manually update the same VPP app. The App Store shows the error seen when UpdateBehavior is absent: “ cannot be updated because it was refunded or purchased with a different Apple Account.” Also, in this case, the user has no way to purchase the (free) app by their own as the app shows as owned/managed by MDM server. We have to remove the declaration, let the user purchase the same app, then re-deploy the declaration to allow the user to click that "Update" button when a new version for that app is available. Additionally, we’re unsure about the criteria/timing for automatic VPP app updates under DDM. After a new version became available, we waited several hours but the app did not auto-update. Repro summary App: VPP, device-assigned license Declaration: AutomaticAppUpdates = AlwaysOn, install required Device A: not signed into App Store → manual update allowed Device B: signed into App Store → manual update blocked with “refunded/different account” error Auto-update did not occur after waiting several hours post-release Any guidance, confirmation of expected behavior, or tips on additional logging we should collect (e.g., specific App Store / MDM / DDM logs and subsystems) would be greatly appreciated. If this is a known issue or requires a Feedback Assistant report, we’re happy to file one. Thanks,

Before iOS26.1, allowCamera set false, all app can't use camera. On iOS26.1, allowCamera set false, removes camera icon from the Home Screen, but third app can still use camera, such as Safari and other apps that can call camera. Is it a bug or a new features？

Details: Device: iPhone 12 Pro Max System: iOS 26.1 beta 2 Issue Description: When testing MDM device restriction capabilities on iOS 26.1 beta 2, I found that the allowCamera restriction does not work as expected. Observed Behavior: • On a BYOD device: When allowCamera is set to false, the Camera and FaceTime apps disappear from the Home Screen, as expected. However, third-party apps (such as WeChat) can still access the camera and take photos. • On earlier versions (e.g. iOS 26.0.1): Setting allowCamera to false correctly blocks all apps, including third-party apps, from accessing the camera. Initially, I assumed Apple might have changed this restriction behavior so that allowCamera only applies to supervised devices. However, after testing on supervised devices, I found that even there, when allowCamera is set to false, the Camera and FaceTime apps are hidden, but third-party apps can still use the camera. This indicates that the restriction is not functioning correctly in iOS 26.1 beta 2. Expectation: When allowCamera is set to false, all camera access — including third-party apps — should be blocked. Request: Could someone from Apple’s development or MDM team confirm whether this is an expected behavior change or a potential bug in iOS 26.1 beta 2?

I desperately need help with this issue. Are there any known issues regarding MDM profiles not installing on iPhone 17? Too many cases are being reported.

Target Device: iPhone 13, iOS 18.5, enroll to MDM by enrollment profile Command: Response: Anyone could help?

We use Device Management Profile to restrict all apps from using camera on unsupervised devices. It works fine until iOS 26.1 beta. In iOS 26.1, only the camera icon is removed from Home screen, the third party apps can still use camera. In our scenario, the camera of employees' iPhones are disabled when they enter the factory and are restored when they leave. According to the documentation, disabling camera on unsupervised devices is deprecated. But supervision is not feasible option because these iPhones are owned personally by employees. Is there any new solution for camera restriction on unsupervised devices? Thanks.

I am needing to access the ABM API via C#. Searching has directed me to use BouncyCastle. I have downloaded the PEM file. However, using the following: using (var reader = File.OpenText(pemFilePath)) { var pemReader = new PemReader(reader); var keyObject = pemReader.ReadObject(); I get the error "problem creating EC private key: System.NullReferenceException: Object reference not set to an instance of an object."

We are expering frequent delays recently when associating a device serial with the adamid of an app in our business manager account. I get an event id back when calling the /associate api but when i check the status of that event id is can be sat in a pending state for sometimes several hours. Need to understand why and if its a configuration issue

Why don't obtain equipment list (https://mdmenrollment.apple.com/server/devices) interface returns "device_family" contour information. This interface only returns some fields, and many field values are not returned

I'm writing to point out a potential structural error in an example of the DeclarativeManagement command. This could cause significant confusion for developers implementing the MDM protocol. The standard structure for a server-to-device MDM command requires CommandUUID and the Command dictionary to be siblings under the top-level dictionary. The CommandUUID serves as a top-level identifier for the entire command envelope. This is the correct, expected structure: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Command</key> <dict> <key>Command</key> <dict> <key>RequestType</key> <string>DeclarativeManagement</string> </dict> </dict> <key>CommandUUID</key> <string>0001_DeclarativeManagement</string> </dict> </plist> This is an example of the incorrect structure I've seen: <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Command</key> <dict> <key>CommandUUID</key> <string>0001_DeclarativeManagement</string> <key>Command</key> <dict> <key>RequestType</key> <string>DeclarativeManagement</string> </dict> </dict> </dict> </plist>

There is a longstanding restriction payload for supervised iOS devices that disables "Erase All Content and Settings." We have been experimenting with supervised watches paired with supervised phones that have that payload applied, and yet "Erase All Content and Settings" remains available on the watch. Is this: – a) An error with our payload? Should we be sending something else? – b) A bug in watchOS supervision? – c) A deliberate design choice? If so, what is the rationale for preventing organizations from maintaining this very basic level of control over devices they may be configuring and dispatching into the field?

When using the SoftwareUpdateEnforcementSpecific to target an update to iPad OS 18.7.1, will the update be triggered to be downloaded immediately after the iPad has an active Internet connectivity? Or, if the SoftwareUpdateSettingsAutomaticActionsObject download string is set to AlwaysOff, will this mean that the update enforced will not start downloading automatically, but only when the user decides? I am trying to understand how these two can be combined together or if they work independently, as while trying to enforce a specific version, we need to eliminate the possibility to download an iPad OS version using cellular data, as our devices have an eSIM installed and the cost of using that for the iOS updates will be quite high. Maybe there is a setting to only allow the iOS updates to be downloaded via Wi-Fi. Thanks!

I encounter a connection error with Apple Configurator v2.18 when, after making changes in macOS Sequel 15.6.1, I want to apply and transfer the changes to the iPhone icon layout in iOS 26: Apple Configurator v2.18 crashes and returns an error message: ‘Try the operation again. If it fails, quit the application, launch it again, and try again. [NSCocoaErrorDomain – 0x1001 (4097)]’ I have done some research, and it seems that this bug has been identified and fixed in Apple Configurator 2 v2.19 (Build 10434). Have you encountered this problem? Do you know where to find version v2.19? This fixed version does not appear to have been released yet, and Apple support has been unable to help me. Thank you all for your help.

Hi everyone, I want to enable Single App Mode (SAM) for my custom app that’s installed on the device. However, my device is not supervised. Is there any way to: Enable Single App Mode without supervising the device? Any guidance or workaround would be appreciated. Thanks, Arnab Lahiri

Dear Apple Developer Team, Following the rollout of iOS 26.x and the introduction of the iPhone 17, we have identified a critical issue affecting Mobile Device Management (MDM) enrolment and restore operations. The issue appears to stem from the Device Management Profile configuration 'do_not_use_profile_from_backup' within Apple Business Manager (ABM), which currently defaults to False. This setting should be modified to True to ensure proper functionality. When the profile remains set to False, organisations leveraging MDM encounter repeated failures during device backup and restore operations. Specifically, restoring a supervised or managed device triggers a persistent MDM registration loop, effectively preventing deployment of iPhone 17 devices in managed environments. We recommend that Apple review and adjust the default Device Management Profile property within ABM to address this issue and restore full MDM compatibility for iOS 26.x and later.
