How to Enable Supervision Mode on Wi-Fi-Only Apple TV?
I'm trying to enable Supervision Mode on a Wi-Fi-only Apple TV (Apple TV 4K) using Apple Configurator on macOS, but I’m unable to get the device into supervised state. What I’ve tried so far: Connected Apple TV to Mac using Apple Configurator pairing mode via same wifi connection Erased and prepared the device Followed the "Prepare" workflow to supervise the device Issue: After preparation completes, the device does not appear as supervised in Apple Configurator.

VPP Asset allocation getting delayed
We are experiencing a critical issue where VPP app installations are consistently taking an excessive amount of time, leading to significant delays in asset association. We are deployionThis is a systemic problem that affects all VPP apps, not just an isolated case. Apps: 39470db7-e475-4269-9709-c80641657027 => com.zimride.instant d0876900-2579-463e-99f1-b7c85ef5c5e8 com.microsoft.azureauthenticator Troubleshooting: We have performed extensive troubleshooting and can confirm the following: VPP Token: The VPP token has been successfully renewed and is currently active and valid. License Availability: We've verified that there are sufficient VPP licenses available for the apps being deployed. Device Status: We've attempted the following on the affected devices: Restarted the devices. Switched to different Wi-Fi networks. Uninstalled and re-installed the apps. App Status: The issue is not limited to a single app; all VPP apps are failing to install. License Revocation: We attempted to revoke and reassign licenses for some devices, but this did not resolve the issue. The app was not pushed, and the pending status remained. Troubleshooting: Through our internal investigation, we have determined that the core issue is that the Asset Association Status is consistently taking excessive time. This seems to be preventing the app installation queue from processing. We have observed a significant delay in the processing of events within the Notification Channel. The time between the event being created and a response being received is excessively long, indicating a potential backlog or issue. We have included a few recent examples below for your reference: Event ID: 39470db7-e475-4269-9709-c80641657027 com.zimride.instant Created Time: 2025-08-26 01:02:04 Response Time: 2025-08-26 01:34:05 Event ID: d0876900-2579-463e-99f1-b7c85ef5c5e8 com.microsoft.azureauthenticator Created Time: 2025-08-25 21:16:29 Response Time: 2025-08-25 22:21:07 We would appreciate your help in the following areas: Resolution: Could you provide any known solutions or workarounds for an asset association status that is taking excessive amount of time'? Best Practices: Are there any recommended best practices or additional parameters we should be checking with the MDM that might influence the queueing of VPP app assignments? Queueing Parameters: Could you provide insight into the parameters or conditions that can affect the queueing and processing of VPP app installations on Apple's servers? Please let us know if there is any additional information or logs we can provide.

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

macOS login issue with federation
We have couple of devices that are registered into Platform SSO, and we have been noticing an issue when the user tried to login. After the users enters the password and hit the return key nothing happens, they need to hit the return key probably 10-15 times in order for the login to happen, the password entered is the correct one and it's just that hitting the return key doesn't invoke the login. On checking the log of the device one unusual thing that we noticed as compared to a different device where the login is working in a single go is that the AppSSOAgent or AppSSODaemon process were not getting invoked

Enterprise Account: Can we use corporate credit card under different name?
We’re using the Apple Developer Enterprise Program for internal app distribution. The Apple ID is a generic one using our domain email, but the Account Holder is a real person with authority in the organization. For the payment method, we plan to use a corporate credit card — but it is issued under a different staff name (e.g. card under Chief, but Account Holder is IT Head). Just want to check: • Is this setup acceptable? • Will Apple reject the enrollment/renewal if the card name doesn’t match the Account Holder? • What’s the best practice in this case to avoid delays or verification issues? Appreciate any guidance or experience from the community. Thanks!

Question/Feature Request: String-based Version Specification (x.y.z) for `InstallBehavior.Version` in App:Managed
Hello, I'm currently working on implementing app installation features, referencing the app.managed.yaml declaration on GitHub: https://github.com/apple/device-management/blob/0a4527c5ea21825fd23e08273ccdb9e2302458ce/declarative/declarations/configurations/app.managed.yaml My question pertains to the InstallBehavior.Version key. The current specification indicates its type as <integer>: key: Version title: Version supportedOS: iOS: introduced: '26.0' macOS: introduced: '26.0' visionOS: introduced: '26.0' type: <integer> Is there a way to specify the app version using a string format, such as x.y.z, instead of the integer (App Store External Version Identifier - EVID)? Allowing for a simpler version specification would make app version management through MDM more flexible and efficient. I believe this would significantly streamline the deployment and operation of Apple devices within organizations. Any guidance or consideration for this would be greatly appreciated. Thank you.

CNContact instantMessage field duplicates after serializaiton/deserialization
Hello folks, I stumbled upon a weird CNContact serialization problem. I use the Contacts framework to update the AIM field, which is one of the instantMessageAddresses within a single Contact. Here is the simplified code I used: func updateAIMFieldOn(contact: CNContact, aimValue: String) { do { guard let mutableContact = contact.mutableCopy() as? CNMutableContact else { logger.error("[CM] Couldn't update contact with aim \(aimValue)") return } var updatedAddresses = mutableContact.instantMessageAddresses updatedAddresses.append(CNLabeledValue(label: "", value: CNInstantMessageAddress(username: aimValue, service: CNInstantMessageServiceAIM))) mutableContact.instantMessageAddresses = updatedAddresses let saveRequest = CNSaveRequest() saveRequest.update(mutableContact) try CNContactStore().execute(saveRequest) logger.verbose("Contact's AIM updated successfully!") } catch { logger.error("Couldn't update contact") } } And after serializing the contact to data, and then deserializing, the contact got two AIM fields with the same value: X-AIM;type=pref:some:part:of_my_aim_value IMPP;X-SERVICE-TYPE=AIM;type=pref:some:part:of_my_aim_value Why does it work in this manner? Is it possible that ":" char causes that? Format of my aim username is {some:part:of_my_aim_value}. I didn't find any information in the docs. Thanks!

Intune MAM Files app exception
Hi all, I'm implementing Intune MAM to secure applications on iOS. However, I need my users to be able to save files (e.g. attachments in an email in the Outlook app) to iOS Files. To do so, I'm trying to put Files in exception of my Intune MAM policy and I need to obtain the Files "CFBundleURLSchemes" value from the info.plist file of the Files app. I'm not able to get that information. Are any of you able to get that somehow? Thanks!

Unable to get inbound and outbound byte count in Content Filter report.
Hello, I am building a Content Filter app for iOS and would like to get access to some information about network connections that are happening on the device. I managed to have the handle(_ report: NEFilterReport) method of my NEFilterControlProvider called, but the bytesOutboundCount and bytesInboundCount properties of the report are always 0. How can I have the real byte count of the connection ?

subsequential normal notification will be surpassed if Critical display on the top banner while screen is on iOS
Hi There Our app is used in the hospital field and receives remote APNS via the Notification Service Extension. We found a scenario where screen is on, our app is in background, if a "Critical" notification is displayed as a banner at the top of the screen, subsequent normal notifications will be suppressed and no sound will play. Only after the user swipes away the critical notification will the normal notification appear and play a sound. is this as expected? I could not find any document on such case from Apple. Thanks.

macOS ACME certificate not appearing in System Keychain
Finally got to the stage where the ACME certificate profile is successfully installed. However, the public key/certificate itself isn't appearing in the System Keychain. I'm not sure if this is normal or if it's an indication that something went wrong after the profile installation. Unfortunately, I didn't study the log detail at the time and I'm uncertain of how to retrieve those logs from two days ago for the ACME activities. Can anyone confirm that macOS 26 should be storing ACME-retrieved MDM profile-based certificates in the System Keychain? If they should be there, what can possibly go wrong? The most obvious issue I can see is that the ACME server has requested the certificate with two CN's, which comes from the MDM profile asking for the subject against CN and the OID (2.5.4.3). Both CN's are identical. I'm surprised the profile installed if something is wrong. At first, I assumed Apple had decided to stop installing the certificates into the System Keychain.

Request for Update to ABM Device Management Profile Setting – iOS 26.x / iPhone 17 MDM Restore Loop
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.

ACME Managed Device Attestation - Saving certificate to Kerychain
Hello! I’m testing certificate issuance using a locally running Smallstep step-ca ACME server with the device-attest-01 challenge. I’ve created a custom MDM profile for this purpose. When I install the profile, the certificate is issued successfully, but it is not saved to the Keychain as stated in the documentation. I can only see the certificate via mdmclient or in the Wi-Fi settings dropdown menu. Is this expected behavior, or are there additional settings that need to be included in the MDM profile?

virtual meeting extension
Hello, I have implemented my virtual meeting extension and my application shows no issues in the calendar application, with a join button displayed. Everything is great!. However, with the help of EKEventEditViewController and EKEvent instances, when creating an event from the main target of the application using EventKitUI, the event will not be displayed as a virtual meeting. I have seen that other applications like Zoom have already implemented this, and I find it difficult to find relevant documentation on how to link events created by the program to virtual meetings. How do I set an event as a meeting when I want to add it to the main program? In addition, the function in the VirtualConferenceProvider.swift file of the extension program fetchVirtualConference(identifier: EKVirtualConferenceRoomTypeIdentifier, completionHandler: @escaping (EKVirtualConferenceDescriptor?, (any Error)? )->Void) How are the parameters in this function obtained? It's impossible for every conference related link to be the same

No prompt/notification on device when using ABM/ASM MDM migration deadline in iOS 26
I'm are attempting to use the device management migration feature in Apple Business Manager / Apple School Manager (for devices running iOS 26 / iPadOS 26) to re-assign managed devices from one MDM server to another. We followed the published procedure (select device(s) → Assign Device Management → Set deadline → Continue). However, we are observing that on the device side, no notification or prompt appears to the user (such as “Enrollment Required” or “Your organization requires this device to enroll in a different device management service”), even after the migration deadline has passed. Here are the environment details: Device OS version: (iOS 26.1) Device ownership: enrolled via Automated Device Enrollment MDM re-assignment in ABM: old MDM server(name: https://dev5.clomo.com/panel/mackey-dev/ ) → new MDM server (name: https://obliging-bunny-equally.ngrok-free.app/ ) Deadline set: (12/10/2025 12:00 AM) Network connectivity: confirmed online at deadline time We would like to know: Under what exact conditions will the device display the notification/prompt, and what common mis-configurations prevent it from appearing? Is there any device log or activity indicator in ABM/ASM to confirm that the migration instruction has been sent to the device? In cases where the prompt does not appear, what troubleshooting steps can we perform on the device (or in the MDM/ABM configuration) to correct it?

Question/Feature Request: String-based Version Specification (x.y.z) for `InstallBehavior.Version` in App:Managed
Hello, I'm currently working on implementing app installation features, referencing the app.managed.yaml declaration on GitHub: https://github.com/apple/device-management/blob/0a4527c5ea21825fd23e08273ccdb9e2302458ce/declarative/declarations/configurations/app.managed.yaml My question pertains to the InstallBehavior.Version key. The current specification indicates its type as <integer>: key: Version title: Version supportedOS: iOS: introduced: '26.0' macOS: introduced: '26.0' visionOS: introduced: '26.0' type: <integer> Is there a way to specify the app version using a string format, such as x.y.z, instead of the integer (App Store External Version Identifier - EVID)? Allowing for a simpler version specification would make app version management through MDM more flexible and efficient. I believe this would significantly streamline the deployment and operation of Apple devices within organizations. Any guidance or consideration for this would be greatly appreciated. Thank you.

CNContact instantMessage field duplicates after serializaiton/deserialization
Hello folks, I stumbled upon a weird CNContact serialization problem. I use the Contacts framework to update the AIM field, which is one of the instantMessageAddresses within a single Contact. Here is the simplified code I used: func updateAIMFieldOn(contact: CNContact, aimValue: String) { do { guard let mutableContact = contact.mutableCopy() as? CNMutableContact else { logger.error("[CM] Couldn't update contact with aim \(aimValue)") return } var updatedAddresses = mutableContact.instantMessageAddresses updatedAddresses.append(CNLabeledValue(label: "", value: CNInstantMessageAddress(username: aimValue, service: CNInstantMessageServiceAIM))) mutableContact.instantMessageAddresses = updatedAddresses let saveRequest = CNSaveRequest() saveRequest.update(mutableContact) try CNContactStore().execute(saveRequest) logger.verbose("Contact's AIM updated successfully!") } catch { logger.error("Couldn't update contact") } } And after serializing the contact to data, and then deserializing, the contact got two AIM fields with the same value: X-AIM;type=pref:some:part:of_my_aim_value IMPP;X-SERVICE-TYPE=AIM;type=pref:some:part:of_my_aim_value Why does it work in this manner? Is it possible that ":" char causes that? Format of my aim username is {some:part:of_my_aim_value}. I didn't find any information in the docs. Thanks!

VPP app installation delayed
During VPP app installation, the app-device asset association event took longer than the usual maximum of 30 seconds to complete, regardless of the number of app licenses involved.

Intune MAM Files app exception
Hi all, I'm implementing Intune MAM to secure applications on iOS. However, I need my users to be able to save files (e.g. attachments in an email in the Outlook app) to iOS Files. To do so, I'm trying to put Files in exception of my Intune MAM policy and I need to obtain the Files "CFBundleURLSchemes" value from the info.plist file of the Files app. I'm not able to get that information. Are any of you able to get that somehow? Thanks!

Unable to get inbound and outbound byte count in Content Filter report.
Hello, I am building a Content Filter app for iOS and would like to get access to some information about network connections that are happening on the device. I managed to have the handle(_ report: NEFilterReport) method of my NEFilterControlProvider called, but the bytesOutboundCount and bytesInboundCount properties of the report are always 0. How can I have the real byte count of the connection ?

subsequential normal notification will be surpassed if Critical display on the top banner while screen is on iOS
Hi There Our app is used in the hospital field and receives remote APNS via the Notification Service Extension. We found a scenario where screen is on, our app is in background, if a "Critical" notification is displayed as a banner at the top of the screen, subsequent normal notifications will be suppressed and no sound will play. Only after the user swipes away the critical notification will the normal notification appear and play a sound. is this as expected? I could not find any document on such case from Apple. Thanks.

macOS ACME certificate not appearing in System Keychain
Finally got to the stage where the ACME certificate profile is successfully installed. However, the public key/certificate itself isn't appearing in the System Keychain. I'm not sure if this is normal or if it's an indication that something went wrong after the profile installation. Unfortunately, I didn't study the log detail at the time and I'm uncertain of how to retrieve those logs from two days ago for the ACME activities. Can anyone confirm that macOS 26 should be storing ACME-retrieved MDM profile-based certificates in the System Keychain? If they should be there, what can possibly go wrong? The most obvious issue I can see is that the ACME server has requested the certificate with two CN's, which comes from the MDM profile asking for the subject against CN and the OID (2.5.4.3). Both CN's are identical. I'm surprised the profile installed if something is wrong. At first, I assumed Apple had decided to stop installing the certificates into the System Keychain.

Request for Update to ABM Device Management Profile Setting – iOS 26.x / iPhone 17 MDM Restore Loop
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.

ACME Managed Device Attestation - Saving certificate to Kerychain
Hello! I’m testing certificate issuance using a locally running Smallstep step-ca ACME server with the device-attest-01 challenge. I’ve created a custom MDM profile for this purpose. When I install the profile, the certificate is issued successfully, but it is not saved to the Keychain as stated in the documentation. I can only see the certificate via mdmclient or in the Wi-Fi settings dropdown menu. Is this expected behavior, or are there additional settings that need to be included in the MDM profile?

virtual meeting extension
Hello, I have implemented my virtual meeting extension and my application shows no issues in the calendar application, with a join button displayed. Everything is great!. However, with the help of EKEventEditViewController and EKEvent instances, when creating an event from the main target of the application using EventKitUI, the event will not be displayed as a virtual meeting. I have seen that other applications like Zoom have already implemented this, and I find it difficult to find relevant documentation on how to link events created by the program to virtual meetings. How do I set an event as a meeting when I want to add it to the main program? In addition, the function in the VirtualConferenceProvider.swift file of the extension program fetchVirtualConference(identifier: EKVirtualConferenceRoomTypeIdentifier, completionHandler: @escaping (EKVirtualConferenceDescriptor?, (any Error)? )->Void) How are the parameters in this function obtained? It's impossible for every conference related link to be the same

No prompt/notification on device when using ABM/ASM MDM migration deadline in iOS 26
I'm are attempting to use the device management migration feature in Apple Business Manager / Apple School Manager (for devices running iOS 26 / iPadOS 26) to re-assign managed devices from one MDM server to another. We followed the published procedure (select device(s) → Assign Device Management → Set deadline → Continue). However, we are observing that on the device side, no notification or prompt appears to the user (such as “Enrollment Required” or “Your organization requires this device to enroll in a different device management service”), even after the migration deadline has passed. Here are the environment details: Device OS version: (iOS 26.1) Device ownership: enrolled via Automated Device Enrollment MDM re-assignment in ABM: old MDM server(name: https://dev5.clomo.com/panel/mackey-dev/ ) → new MDM server (name: https://obliging-bunny-equally.ngrok-free.app/ ) Deadline set: (12/10/2025 12:00 AM) Network connectivity: confirmed online at deadline time We would like to know: Under what exact conditions will the device display the notification/prompt, and what common mis-configurations prevent it from appearing? Is there any device log or activity indicator in ABM/ASM to confirm that the migration instruction has been sent to the device? In cases where the prompt does not appear, what troubleshooting steps can we perform on the device (or in the MDM/ABM configuration) to correct it?
