Hello all, We have built our own MDM solution as we plan to support quite a few devices running iOS. Manual activation is running fine and devices are checking in. We have setup ABM with Device management service setup and linked to our MDM. We have added reseller via Apple customer number and purchased devices are showing in ABM. We have setup default management service assignment as well. When we are setting up a device it gives an error: Remote Management The configuration for your iPhone could not be downloaded from . cancelled Error in the device log is as follows: Jun 11 14:16:36 iPhone Setup(DMCUtilities)[626] : <DMCHTTPRequestor: 0x84cfd7d40> cannot accept the authentication method NSURLAuthenticationMethodClientCertificate Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Task <663D2346-4B73-4DB2-A134-B1A7DC58E70B>.<1> auth completion disp=2 cred=0x0 Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Task <663D2346-4B73-4DB2-A134-B1A7DC58E70B>.<1> summary for task failure {transaction_duration_ms=285, response_status=-1, connection=7, reused=1, reused_after_ms=0, request_start_ms=0, request_duration_ms=0, response_start_ms=0, response_duration_ms=0, request_bytes=0, request_throughput_kbps=0, response_bytes=0, response_throughput_kbps=0, cache_hit=false} Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: TLS Client Certificates encountered error 1:89 Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Task <663D2346-4B73-4DB2-A134-B1A7DC58E70B>.<1> finished with error [-999] Error Domain=NSURLErrorDomain Code=-999 UserInfo={NSErrorFailingURLStringKey=, NSErrorFailingURLKey=, _NSURLErrorRelatedURLSessionTaskErrorKey=, _NSURLErrorFailingURLSessionTaskErrorKey=, NSLocalizedDescription=} Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: encountered error(1:89) Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: cleaning up Jun 11 14:16:36 iPhone Setup(CFNetwork)[626] : Connection 7: summary for unused connection {protocol="http/1.1", domain_lookup_duration_ms=0, connect_duration_ms=0, secure_connection_duration_ms=0, private_relay=false, idle_duration_ms=0} Jun 11 14:16:36 iPhone Setup(DMCUtilities)[626] : <DMCHTTPRequestor: 0x84cfd7d40> failed to communicate with the MDM server.

Hi Community, The Leverage macOS has with Bootstrap token is immense using the same for Software Updates, Erase Device and new Local Account Creation in System Settings While I refer From IT Deployment Guide Which States the below For a Mac with macOS 10.15.4 or later, when a secure token-enabled user logs in for the first time, macOS generates a bootstrap token and escrows it to a device management service. I even tested out the Statement using Automated Device Enrollment Workflow ( With AutoAdmin Account Only, With Both AutoAdmin Account , Primary Account ) and it Granted BootStrap Token Immediately upon login How ever with User-Initiated Enrollments it differs like below Sometimes upon installation of MDM Profile in macOS Immediately the BootstrapToken is sent to MDM Sometimes the BootStrapToken is not immediately sent, so I need to logout , login with the Secure Token enabled user for macOS to escrow BootStrapToken to MDM Sometimes Even when I followed the pointer as in 2) like logout / login from a SecureToken Enabled user the BootStrapToken is not escrowed to MDM , Which Affects the OSUpdates, Erasing Capabilities to be used precisely with MDM Protocol Can someone Please Help with the Flow for BootStrapToken Generation / issuance to MDM incase for User-Initiated Enrollment

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.

Hello together, I'm currently trying to implement a simple way to use the new LOM commands for our new mac infrastructure. My MDM sollution is a custom instance of MicroMDM. MDM profiles are working fine, but when I send a https://developer.apple.com/documentation/devicemanagement/lom_device_request_command with any command (Reset, PowerON, PowerOFF), then it doesn't reset/restart/start the target Mac. Host X has a device profile and host Y a controller profile. Host/Mac Y = fe80::YYYY:YYYY:YYYY:8608 Host/Mac X = fe80::XX:XXXX:XXXX:cfab Now, if I send a LOM request for Mac Y to reset Mac X, I get the error "Address already in use" on Mac X (logs via log stream) log stream (private logs) And wireshark on Mac X shows there is traffic, but MacX does not respond to anything, not even tcp syn packages. This error is really weird, because there are no special ports running on that mac and I don't know what Port lightsoutmanagementd tries to listen to. lsof | grep LISTEN | grep -i ipv6 launchd 1 root 7u IPv6 0x457f571ac3303fd7 0t0 TCP *:ssh (LISTEN) launchd 1 root 11u IPv6 0x457f571ac33015d7 0t0 TCP *:rfb (LISTEN) launchd 1 root 27u IPv6 0x457f571ac3303fd7 0t0 TCP *:ssh (LISTEN) lightsout 112 root 4u IPv6 0x457f571ac3302ad7 0t0 TCP *:55555 (LISTEN) kdc 143 root 5u IPv6 0x457f571ac33023d7 0t0 TCP *:kerberos (LISTEN) screensha 403 root fp.u IPv6 0x457f571ac33015d7 0t0 TCP *:rfb (LISTEN) (fileport=0x2103) screensha 403 root 3u IPv6 0x457f571ac33015d7 0t0 TCP *:rfb (LISTEN) ARDAgent 535 devops 9u IPv6 0x457f571ac33031d7 0t0 TCP *:net-assistant (LISTEN) Did anyone have the same problem, or maybe can hint me in the right direction?

Attempts to programmatically update or add numerous system-installed certificates (a common practice for organizations that rotate certificates regularly) are blocked, forcing manual, insecure, and error-prone workarounds. The root cause lies in the stricter security protocols implemented in macOS 15, specifically: System Integrity Protection (SIP) and Transparency, Consent, and Control (TCC) Command we are using : sudo security authorizationdb write com.apple.trust-settings.admin

Hi everyone, I'm running an Apple MDM service and encountering an issue where a number of devices stop receiving MDM push commands within 10 days of profile installation, even though everything appears to be set up correctly. Environment: MDM profile is installed and verified (status: OK, result: SUCCESS) Devices are cellular-enabled with no connectivity issues APNs certificate is valid (thousands of other devices are communicating normally) The command being sent to devices is DeviceInformationCommand No "NotNow" response or any check-in received from the affected devices for over a week Issue: We send DeviceInformationCommand to devices to retrieve device information and update the last communication timestamp. However, a subset of devices simply stop responding to this command within 10 days of profile installation. The last communication date is not being updated, and no response — not even a "NotNow" — is coming back from these devices. Since other devices on the same MDM setup are working fine, I've ruled out APNs certificate expiration and general server-side issues. Questions: Are there any known management points or configuration settings that could cause a device to silently stop receiving DeviceInformationCommand shortly after enrollment? What diagnostic steps would you recommend to identify the root cause on the device or server side? Are there any known bugs or reported issues related to this behavior in recent iOS versions? Is there any way to recover the MDM communication without requiring the user to re-enroll? Any insights or suggestions would be greatly appreciated. Thank you!

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.

Requesting com.apple.managed-keychain Entitlement for Enterprise S/MIME Cert Visibility Platform: iOS | Distribution: MDM (Microsoft Intune) | Not App Store We are developing an internal enterprise iOS app (EMS Assist, com.company.supportcompanion) for Company deployed exclusively to Intune-managed devices. Our requirement: Read S/MIME certificates pushed to the device via Intune SCEP profiles to: Confirm cert presence in the MDM-managed keychain Read expiry date (kSecAttrNotValidAfter) to warn users before expiry Distinguish between missing, expired, and valid cert states What we have tried: Standard SecItemCopyMatching query — returns only app-installed certs, not MDM-pushed certs Graph API (deviceConfigurationStates) — confirms profile compliance but does not expose actual cert expiry or keychain presence Our understanding: com.apple.managed-keychain is required for an app to access MDM-managed keychain items on supervised devices, combined with a matching keychain-access-groups entitlement and the cert profile configured as "always available" in MDM. Questions: Is com.apple.managed-keychain the correct entitlement for this use case? Does it apply to SCEP/PKCS-issued certificates specifically, or only other MDM keychain items? Has anyone successfully accessed Intune-pushed S/MIME certs from an iOS app using this entitlement? Any guidance from the community or Apple engineers would be appreciated.

Is there any mechanism to restrict camera usage on a user-owned device, once they have opted in, consented to the restriction, and installed a management profile? Documentation suggests it was possible with allowCamera, but has be deprecated on unsupervised devices. Am I understanding correctly that it's simply not possible anymore unless the device is supervised?

If I have a macOS devices enrolled in MDM, with a DDM policy defined to deliver passcode settings to the device I can run: sudo pwpolicy -getaccountpolicies to see the configuration on the device. I can subsequently run: sudo pwpolicy -clearaccountpolicies Then all passcode policies applied in my declarations are cleared from the device allowing the user to set and use any password they want with no bearing on the delivered passcode settings. I have left my macOS devices for days on and off network and the pwpolicy data never returns. The passcode settings do not restore on the device until I do one of the following: manually re-push all declarations from MDM log off and log back on reboot the computer It was my understanding that DDM was meant to assess device state and self heal on its own without requiring an MDM service to re-push any commands. Based on this finding this seems broken or I may misunderstand how DDM is supposed to work. macOS version: 26.4.1

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

We've put in a feedback assistant request, but not sure if we will get feedback in that channel or not and also want to highlight for others. When replacing a basic passcode profile on a macOS device with a passcode declaration, the user is required to change the password after logging out and back in. Explicitly including the "ChangeAtNextAuth" key set equal to false, set required a password change after logging out and back in. Once the declaration is active and the password has been changed, future updates to the passcode declaration do not require a password change unless the existing password is not compliant. Steps to reproduce: Install a basic passcode profile on a macOS device Ensure the existing password matches the requirements specified in the profile Install a passcode declaration with the same settings as the passcode profile currently installed Remove the traditional passcode profile from the device After the passcode declaration is installed, check the local pwpolicy with the command pwpolicy getaccountpolicies and look for the key policyAttributePasswordRequiredTime Log out of the macOS device Log back into the macOS device and you are presented with a change password prompt Expected result: Simply replacing an existing passcode profile with the exact same settings in a passcode declaration should not require a password change if the existing password is compliant. Actual results: After replacing the passcode profile with a passcode declaration, a password change was required even though the existing password was compliant. Initial testing was done with a macOS VM running 15.5. Additional testing has now been done with a macOS VM running 26.4.1 and the same behavior was observed.

Hi, I have a question regarding the relationship between the Apple Developer Enterprise Program membership and an existing APNs certificate used for MDM. Current Situation We are operating an MDM server. We have already obtained a valid APNs certificate via the Apple Push Certificates Portal. Our Apple Developer Enterprise Program membership is about to expire. The only asset we have in the Enterprise account is the MDM CSR used during the APNs certificate issuance process. Question If the Apple Developer Enterprise Program Membership expires: Will the existing APNs certificate remain valid until its expiration date? Or will it become invalid immediately due to the account expiration? Thank you.

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!

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.

I work at a school in NYC and have a software idea that could better support the new NYC phone ban law than current market options (i.e. Yondr pouches). Right now at my school, students and staff scan a QR code upon entering the building to indicate that they are in the building. They scan again on the way out to indicate they've left the building. This is super helpful for attendance, particularly in emergency situations (fire drills, etc). Imagine if when students scanned their QR code, it also activated an app similar to Opal or ScreenZen, but with an admin preset whitelisted apps. The idea is that this app would default deny access to all apps on students' phones except the admin preset whitelisted ones such as Phone, Calculator, etc. Depending on the age/needs of the student, other apps like Spotify, or medical apps could also be whitelisted. My question is -- is this idea possible to create? We would need admin preset controls to create the preset whitelist. We can't have students picking their own restrictions, as we know most would opt to not restrict at all. We would need an admin dashboard so teachers/admin can see which students have activated the app in the building, and which may be trying to sneakily avoid it. We would ideally need to be able to whitelist both system apps like Phone and Calculator, as well as non-system apps such as Spotify (and medical apps -- we have some students who manage/monitor their Diabetes with an app). I don't have a background in software. I'm a math and health teacher. I've experimented with trying to have friends who majored in CS to create this app for me, but they've all either struggled/lost interest. So I'm also looking for a business partner in this venture. If anyone has any guidance here, it would be so helpful! My boss (Head of School) is super interested in this idea and significantly prefers it to every other alternative that he has encountered. The problem is this idea does not exist yet! Note: I know this is a super similar idea to the app and product "Brick". Notably, though, Brick does not have the ability for admin preset controls, or the admin dashboard. We reached out to the company to see if they're create this for us and they said it's a back burner idea that they're aware of, but it's not a priority for them right now. Thank you for any guidance!

Hello, We are currently deploying Apple devices in our organization using Apple Business Manager (ABM) and are looking for a long-term self-hosted MDM solution. We initially considered MicroMDM, but since official support will end in December 2025, we are evaluating NanoMDM. I would like to confirm: Is NanoMDM a stable and production-ready option for long-term use with Apple Business Manager and Automated Device Enrollment (ADE)? Does NanoMDM support all essential features like: Supervision Remote wipe App deployment Configuration profiles Are there any limitations or known issues with using NanoMDM? Are there any other open-source or lightweight MDM solutions Apple developers recommend that are actively maintained? We are aiming for a reliable, secure, and future-proof self-hosted MDM setup. Any guidance or shared experience would be greatly appreciated. Thanks, Vijay Pratap Singh

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.
