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.

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.

We have a WebContentFilter that has an AllowList with a couple of domains and a DenyList that includes www.apple.com. This works on iOS18.x but doesn't work in iOS26 as www.apple.com can be reached. https://support.apple.com/en-gb/guide/deployment/depc77c9609/web Indicates that .apple.com is always accessible but evidence seems to indicate this wasn't the case pre iOS26. An older version of this page https://web.archive.org/web/20220427202204/https://support.apple.com/en-gb/guide/deployment/depc77c9609/web has no mention of .apple.com although field names are also different. Has this change come about due to the filtering changes introduced in iOS26 and is there any way we can still block .apple.com going forward. Would a content plugin be an options ?

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?

Hi, I’m testing the ClearPasscode MDM command: https://developer.apple.com/documentation/devicemanagement/clear-passcode-command Question: If a user enters the passcode incorrectly multiple times and the device becomes temporarily locked (e.g., “Try again in X minutes”) or reaches “Security Lockout”, can ClearPasscode still be executed successfully while the device is in that state? {'ErrorCode': 5013, 35708 'ErrorDomain': 'MCPasscodeErrorDomain', 35709 'LocalizedDescription': '\xe3\x81\x93...x89', 35710 'USEnglishDescription': 'The passcode cannot be cleared (-1)'} If it depends on conditions (e.g., supervised vs. user enrollment, availability of UnlockToken, network/check-in state), could you clarify which conditions are required? Thank you.

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>

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?

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.

Hello, My Apple Developer Program subscription is active in Apple subscriptions and valid until March 19, 2027, but my developer account is still not activated and I have not received the confirmation email. The purchase was completed through the Apple Developer app on my wife’s iPhone, but the enrollment was for my own Apple Account. In the app, I see the message: “You’ll receive an email soon.” Has anyone had the same issue? How was it resolved? Thank you.

Steps to Reproduce Step 1: Fetch Initial Device List Called the device list endpoint to retrieve all devices and saved the cursor: GET https://mdmenrollment.apple.com/server/devices Step 2: Modify Devices Added and deleted several devices via https://business.apple.com/ Step 3: Sync Without Pagination Called the sync endpoint using the cursor from Step 1 (no limit): GET https://mdmenrollment.apple.com/devices/sync?cursor={step1_cursor} Result: Returned 3 device records as expected: { "devices": [ { "serial_number": "F70JJ4C16L", "op_type": "added", "op_date": "2025-12-11T07:05:05Z" }, { "serial_number": "F70JJ4C16L", "op_type": "deleted", "op_date": "2025-12-11T07:04:36Z" }, { "serial_number": "C8RWGXZXJWF5", "op_type": "deleted", "op_date": "2025-12-11T07:04:52Z" } ], "more_to_follow": false } Step 4: Sync With Pagination (First Page) Called the sync endpoint using the same cursor from Step 1 with limit=1: GET https://mdmenrollment.apple.com/devices/sync?cursor={step1_cursor}&limit=1 Result: Returned 1 record with more_to_follow: true — indicating more data exists: { "devices": [ { "serial_number": "F70JJ4C16L", "op_type": "added", "op_date": "2025-12-11T07:05:05Z" } ], "more_to_follow": true, "cursor": "MTowOjE3NjU0MzgyNDI5ODc6..." } Step 5: Sync With Pagination (Second Page) Called the sync endpoint using the cursor from Step 4 with limit=1: { "devices": [], "more_to_follow": false } Expected Behavior When paginating with limit=1, the API should return all 3 records across 3 sequential requests. Actual Behavior Without pagination: Returns 3 records ✓ With pagination (limit=1): Returns only 1 record, then empty array ✗ 2 records are missing when using pagination. Impact This inconsistency makes the sync API unreliable for incremental device synchronization workflows.

Hello, I’d like to clarify the technical limitations around app updates in an Apple School Manager (ASM) + MDM environment. Environment • iOS/iPadOS devices supervised and managed via Apple School Manager • Apps are distributed via ASM (VPP / Custom App) and managed by MDM • Apps are App Store–signed (not Enterprise/In-House) • Some apps include NetworkExtension (VPN) functionality • Automatic app updates are enabled in MDM Question From a technical and platform-design perspective, is it possible to: Deploy app updates for ASM/MDM-distributed App Store apps via a separate/custom update server, and trigger updates simultaneously across all managed devices, bypassing or supplementing the App Store update mechanism? In other words: • Can an organization operate its own update server to push a new app version to all devices at once? • Or is App Store + iOS always the sole execution path for installing updated app binaries? ⸻ My current understanding (please correct if wrong) Based on Apple documentation, it seems that: 1. App Store–distributed apps cannot self-update • Apps cannot download and install new binaries or replace themselves. • All executable code must be Apple-signed and installed by the system. 2. MDM can manage distribution and enable auto-update, but: • MDM cannot reliably trigger an immediate update for App Store apps. • Actual download/install timing is decided by iOS (device locked, charging, Wi-Fi, etc.). 3. Custom update servers • May be used for policy decisions (minimum allowed version, feature blocking), • But cannot be used to distribute or install updated app binaries on iOS. 4. For ASM-managed devices: • The only supported update execution path is: App Store → iOS → Managed App Update • Any “forced update” behavior must be implemented at the app logic level, not the installation level. ⸻ What I’m trying to confirm • Is there any supported MDM command, API, or mechanism that allows: • Centralized, immediate, one-shot updates of App Store apps across all ASM-managed devices? • Or is the above limitation fundamental by design, meaning: • Organizations must rely on iOS’s periodic auto-update behavior • And enforce version compliance only via app-side logic? ⸻ Why this matters In large school deployments, delayed updates (due to device conditions or OS scheduling) can cause: • Version fragmentation • Inconsistent behavior across classrooms • Operational issues for VPN / security-related apps Understanding whether this limitation is absolute or if there is a recommended Apple-supported workaround would be extremely helpful. Thanks in advance for any clarification

I am using system_profiler command to check on the installed application list from mac device. **Terminal command to check installed java version - ** But while running /usr/sbin/system_profiler SPApplicationsDataType -xml , I cant able to find Java as an installed application. Is this a known issue or do we have any alternative workaround to fetch the same?

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.

We are developing an MDM (Mobile Device Management) solution for device management purposes, and our current implementation process is as follows: 1. Configure DEP profile to obtain profile_uuid We configured a DEP profile with the following parameters to retrieve the profile_uuid: { "allow_pairing": true, "anchor_certs": [], "auto_advance_setup": true, "await_device_configured": false, "configuration_web_url": "", "department": "test define profile", "devices": ["MNWF07QD9M"], "is_mandatory": false, "is_mdm_removable": false, "is_multi_user": false, "is_supervised": true, "language": "zh", "org_magic": "", "profile_name": "Enrollment Profile - MNWF07QD9M", "region": "cn", "skip_setup_items": [ "Accessibility", "ActionButton", "Android", "Appearance", "AppleID", "AppStore", "Biometric", "CameraButton", "DeviceToDeviceMigration", "Diagnostics", "EnableLockdownMode", "FileVault", "iCloudDiagnostics", "iCloudStorage", "iMessageAndFaceTime", "Intelligence", "Keyboard", "MessagingActivationUsingPhoneNumber", "Passcode", "Payment", "Privacy", "Restore", "RestoreCompleted", "Safety", "ScreenTime", "SIMSetup", "Siri", "SoftwareUpdate", "SpokenLanguage", "UpdateCompleted", "WatchMigration", "WebContentFiltering" ], "supervising_host_certs": [], "support_email_address": "", "support_phone_number": "", "url": "https://mdmp.com/mdm/apple/enroll?shopId=1" } We sent a POST request to the /profile endpoint with the above payload, and the response returned the profile_uuid: 605FB5C274303C19189C9B99DCD3280D. 2. Assign the profile We sent a POST request to the /profile/devices endpoint, including the aforementioned profile_uuid and the target devices list in the request body. 3. Scan the device with Apple Configurator 2 We used Apple Configurator 2 to scan and enroll the target device. Issue Encountered After the device restarts twice, it fails to retrieve the mobileconfig file from the URL: https://mdmp.com/mdm/apple/enroll. We are using Nginx as the web server and have enabled access logging, but the logs show no incoming requests from the device to the /mdm/apple/enroll endpoint at all. Could you please help identify where we might have made a mistake in this process?

I want to install Chrome extension via configuration profile without user needing to go to System Settings and install profile manually. Can i install configuraation profile by making user only interact with my app?

Hey. If i have a new idea for apple how can i reach out for you?

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.

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.
