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.

Account-Driven Device Enrollment for iPadOS 18.2
Hi, I'm glad to hear that the service discovery process is improved on iOS/iPadOS 18.2 mentioned here. https://support.apple.com/en-ca/guide/deployment/dep4d9e9cd26/1/web/1.0 I tried it on my development MDM server. Set default MDM for iPad to my development MDM server on Apple Business Manager. Call the new API https://developer.apple.com/documentation/devicemanagement/account_driven_enrollment_profile and 200 OK is returned However the service discovery fails with the following error. Invalid well-known response for https://{my email's comain name}/.well-known/com.apple.remotemanagement?user-identifier={my email}&model-family=iPad: <NSHTTPURLResponse: 0x300a9f420> Invalid well-known response for https://axm-servicediscovery.apple.com/mdmBaseURL?user-identifier={my email}&model-family=iPad: <NSHTTPURLResponse: 0x3009047a0> It seems fallback process to https://axm-servicediscovery.apple.com/mdmBaseURL actually works but it returns 404 Not Found error. How can we use this awesome feature? Thank you :)

Inquiry: Inconsistent VPP UpdateBehavior with DDM (auto-update timing + manual-update gating)
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,

Unable to Generate MDM CSR for Apple Push Certificates Portal
Hi I am trying to develop Apple MDM solution as a vendor. I got the Vendor certificate from apple developer portal. When I was trying to generate the csr and upload to Portal (https://identity.apple.com/pushcert/) It says Invalid Certificate Signing Request. I had also tried to follow documentation (https://developer.apple.com/documentation/devicemanagement/setting-up-push-notifications-for-your-mdm-customers) but still the same error. Can anyone please guide how to generate the csr.

ABM API Problems with C# and PEM file
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."

Problem applying screen changes (icon arrangement) in iOS 26 using Apple Configurator v2.18 on macOS Sequoia 15.6.1
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.

Platform SSO registration fails on Mobile AD accounts
We are facing an issue with Platform SSO registration on macOS devices for AD-bound user accounts with Microsoft EntraID configuration. We are using the Platform SSO payload on macOS devices integrated with Entra ID, and it works as expected — registration completes successfully, and the password syncs with the Entra ID password. However, when we try the same on macOS devices with AD-bound (mobile) user accounts, the registration does not complete. To elaborate, the process successfully completes the initial WebView authentication but fails at the stage where Apple prompts for the password to sync the local macOS user’s password with the Entra ID password. It does not display any error, and even after entering a valid password, the process does not proceed further. However, when we try the same on a non-AD user account, it works fine. We have checked with Microsoft, and they confirmed that there are no restrictions on their side for AD-bound accounts. Since the issue appears to occur at the Apple system level, they advised us to reach Apple teams on this. Could you please check and let us know how we can proceed with this?

Kernel Panic: SEP Panic (SKS) Triggered by MDM Clear Passcode on iOS 18.3.2 (iPhone 12 Pro)
Hello Developers, We are encountering a consistent Kernel Panic issue on an iPhone device after sending a "Clear Passcode" command via our MDM solution. We're looking for insights or confirmation if others have experienced similar behavior. Device & Environment Details: Device: iPhone13,2 (iPhone 12 Pro) OS Version: iPhone OS 18.3.2 (Build 22D82) (Please note this appears to be a future/beta build identifier) Action Triggering Panic: Sending MDM ClearPasscode command. Roots Installed: 0 (Device is not jailbroken) Incident ID: 4B41C0AE-EE93-4051-BEE4-AB98438C10F0 Panic Log Summary: The kernel panic log clearly indicates the issue originates from the Secure Enclave Processor (SEP). The key panic string is: panic(cpu 3 caller 0xfffffff02357bc1c): SEP Panic: :sks /sks : 0x1000b15fc 0x0003ad60 0x0003ad44 0x100028698 0x10002cae4 0x10002a908 0x10002bc10 0x100045330 [hgggrhlvs] Panic app vers: 1827.80.10 Panic app UUID: 4C066E88-EB93-33C3-BCA7-C5F5474831CC ... Root task vers: AppleSEPOS-2772.80.2 Root task UUID: A39D6C5D-D07D-33EE-85A3-9105A8D93CE2 ... sks /sks 0x329cc/0x326e0/0x1314131413141314 ert/BOOT Use code with caution. The SEP Panic and reference to :sks /sks strongly suggest an issue within the Secure Key Store subsystem of the SEP. The panic occurred on CPU core 3. The kernel backtrace points to the com.apple.driver.AppleSEPManager kernel extension as the immediate caller in the main kernel that initiated the panic process after receiving the signal from the SEP. Analysis/Interpretation: Based on the log, it appears that the MDM ClearPasscode command, which necessarily interacts with the SEP's Secure Key Store via the AppleSEPManager driver, triggered an internal fault or bug within the SEP firmware (AppleSEPOS). This SEP-level panic subsequently caused the main iOS kernel to panic. Questions: Has anyone else encountered similar SEP panics, specifically involving the SKS subsystem, particularly after issuing MDM commands like ClearPasscode on iOS 18.x builds (especially 18.3.2 / 22D82)? Is this a known issue in this specific iOS/SEP firmware version? Are there any suggested workarounds for clearing passcodes via MDM on affected devices/OS versions, or any further diagnostic steps recommended? We appreciate any insights or shared experiences the community might have on this issue. Thank you.

need to bypass the Software Update domains in NETransparentProxy.
Hi team, We need to identify the domains used by macOS Software Update so they can be bypassed by our NETransparentProxy. The Apple support article below lists Software Update and several other Apple service domains. At the moment we’re unsure whether we should only bypass the Software Update and Beta Software domains, or whether we also need to bypass domains used for certificate validation, device management (Apple Business Manager / Apple School Manager / Apple Business Essentials), network provider updates, Apple Diagnostics, etc. We also need the specific IP ranges used exclusively by Software Update. The document shows Apple’s entire IP range; for IPv4 you can allow outbound connections to 17.0.0.0/8. https://support.apple.com/en-in/101555

Intune Auto-Update Issue Following Xamarin Project Migration
We're currently facing an issue with Intune not automatically updating/downloading the updated build/app to end-user ios devices. It's worth noting that we've recently migrated the Xamarin project to a .NET-style SDK in this version. Previously, the app used to update automatically without any problems. We'd appreciate it if you could help us understand what might be causing this issue.
