Hello world! First post here. Developing my first app. It primarily targets supervised and MDM managed devices. A few questions: For supervised devices, is serial number available? I want to get the number and use it for app auto activation Is MDM required for supervised devices? Or, as long as a device is enrolled through Apple Business Manager? Which capacity shall I request for the app? Thanks so much!

Hello ! Currently, we have customers who use about 5,000 devices. In the case of ios26, the phone number is not acquired overall, and 18.x, 17.x, and 16.x are all acquired in half and not acquired in half. https://aninterestingwebsite.com/documentation/devicemanagement/deviceinformationcommand/command-data.dictionary/queries-data.dictionary It seems that it is the right behavior not to acquire it on the specification sheet. However, I wonder when it became impossible to acquire. (There are devices that can be acquired and devices that can't be acquired in the same os version.) Will the devices that are being acquired be blocked someday? When it was developed in 2019, it was in a state that could be acquired in full. I would also like to ask if there is an alternative way to get your phone number. Thank you.

Hi, I was looking for advice on the suitable mac to get for a web app development project for university . Would an Apple MacBook Air 2020 M1 8GB RAM 256GB SSD 13.3" macOS Big Sur, be sufficient ?? Or would I need a newer version !

Hello, I've noticed some unexpected behavior when updating a user's FileVault password. The set up: All actions are performed in virtualized macOS 14 and 15.5 guests on a 15.5 Apple Silicon host. FileVault is enabled. sjsp is a standard user with a Secure Token. The Mac is bound to AD, and the domain is reachable. Reproduction: systemctl -secureTokenStatus sjsp shows it's ENABLED. fdesetup remove -user sjsp fdesetup add -usertoadd sjsp systemctl -secureTokenStatus sjsp shows it's DISABLED. Surprisingly, sjsp is still able to unlock FileVault. Looking at unified logs for opendirectoryd and fdesetup, I see that a password change is being attempted in response to fdesetup add, which is unexpected. default 13:34:41.320883+0100 opendirectoryd Changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) info 13:34:41.321317+0100 opendirectoryd No unlock record exists for E5CC46D7-0C1F-4009-8421-9AA8217CB784 info 13:34:41.321331+0100 opendirectoryd <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) is not a SecureToken user: no unlock record default 13:34:41.321341+0100 opendirectoryd Changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784): user <private> SecureToken, only new password provided, credential <private> default 13:34:41.321454+0100 opendirectoryd Changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) with no existing unlock record info 13:34:41.321857+0100 opendirectoryd No unlock record exists for E5CC46D7-0C1F-4009-8421-9AA8217CB784 default 13:34:41.321873+0100 opendirectoryd Record <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784) is eligible for SecureToken default 13:34:41.322637+0100 fdesetup DMAPFS cryptoUserForMacOSUserForVolume DMErr=-69594 retErr=-69594 outAPFSCryptoUser=(null) default 13:34:41.322699+0100 opendirectoryd While changing password for <private> (E5CC46D7-0C1F-4009-8421-9AA8217CB784): Not adding SecureToken; other unlock records exist, but no existing unlock record provided If I disconnect the network and follow the reproduction steps then the Secure Token is retained.

Hi, My client has already developed an ios app and they need an enterprise account to publish the app. What are the procedures to create enterprise account?

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?

This test setup is Jamf Pro as the MDM with Entra as the IdP. PSSO is working on Sequoia devices. Prior to Tahoe, PSSO required the following three items: An existing local account, the delivery of Company Portal, and a profile containing PSSO payload. Based on the Tahoe announcement, it looks like PSSO is now available during Setup Assistant, removing the requirement of first creating a local account. I assume this means that the requirements now as easy as deploying Company Portal and the PSSO profile during the Pre-Stage policy. I attempted this on the macOS 26 beta 1 and during Setup Assistant, with the PSSO profile delivered, Setup Assistant prompts me to login to my IdP. However, pressing Continue will result in a failure, notifying me that the application required is not available. The continue button is now inactive but a "try again" button is available. This results in the loop of trying and then failing, stating that the required application is not available. I eventually must quit Setup Assistant which exits it and drops me at the login window. The only account that is visible is the management account. A trip into DFU and an IPSW restore then follows. Am I trying this too soon? Is PSSO at Setup Assistant not yet fully supported? Is there another requirement other than delivering Company App in the prestige alongside the profile? I've enabled the beta channel in MAU but there is no newer Company Portal being offered. Any guidance here would be appreciated as this is the PSSO announcement I've been waiting for since the deprecation of Apple Enterprise Connect.

After applying the MDM camera restriction on iOS 26.1 beta 2, the camera availability status is reported incorrectly. After applying the MDM camera restriction [UIImagePickerController isSourceTypeAvailable:UIImagePickerControllerSourceTypeCamera] return YES

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.

Hello everyone, I am looking for technical clarification regarding potential rate limits when automating frequent iOS device resets. In my workflow, I need to reset test devices multiple times per day using the EraseDevice MDM command, often combined with the ReturnToService flag for automated setup. I understand that after a full reset, the device undertakes several critical steps to become operational again, including device activation, system app installation, MDM re-enrollment, and subsequent validation of developer certificates for internally distributed apps. Based on Apple’s documentation and my own observations, I am aware of the following domains being involved in these processes: Device Activation: albert.apple.com, gs.apple.com, captive.apple.com, humb.apple.com, static.ips.apple.com, sq-device.apple.com, tbsc.apple.com, time*.apple.com System App Installation: *.itunes.apple.com, *.apps.apple.com, *.mzstatic.com MDM Enrollment: Communication with Apple ADE servers followed by the MDM server. Developer Certificate Validation: ppq.apple.com, ocsp.apple.com, crl.apple.com My primary question is: Are there any rate limits imposed by Apple’s servers on these specific processes when performed frequently on the exact same device within a short timeframe (e.g., multiple times per day)? Specifically, could anyone provide information regarding potential limits for: Device activation requests? System app downloads post-activation? Automated Device Enrollment checks and subsequent MDM enrollments? Developer certificate validation requests? Additionally, is the list of domains above comprehensive for these processes, or are there other key endpoints involved that I should be aware of regarding potential rate limiting? Understanding these limitations is crucial for ensuring the reliability of automated device management workflows. Thank you for any insights!

Hello, we use an MDM profile that enables FDA for our program. The Identifier is set to be the path to our program. We'd like to have a profile that allows multiple CodeSignatures. Our older programs are signed with a different certificate than the current ones. We tried deploying 2 profiles (one for the 'old certificate' signed binary and the other for the 'new certificate' signed binary). But it looks like that MacOS accepts only one. I have also tried to use ProfileCreator to generate a profile with 2 entries, but it fails to do it. Manually editing the XML file and adding new entries does not work either. I'd like to know if there's a workaround for this issue.

Hello, I’ve run into an issue with a configuration profile on my supervised iPhone. I’m wondering if anyone here might be able to help? The profile contains the allowListedAppBundleIDs key within the restrictions payload. My Apple Watch is paired with the iPhone. The iPhone was supervised manually with Apple Configurator, hence the Apple Watch has not been directly supervised itself. The profile works completely as expected when installed on the phone. As soon as the profile is installed on the iPhone, I can witness the apps on the Apple Watch rearrange themselves as some apps are hidden. So clearly the profile is applying its restrictions to the Apple Watch to some degree. My issue however is that apps listed in the whitelist are hidden from the Watch. The apps that are missing from my Watch are Walkie Talkie, Find My Items, Find My Friends, Messages, Alarm, Remote, Now Playing, Sleep, Meditation and Heart Rate. This is despite the following bundle IDs being listed in the whitelist array: com.apple.findmy.findpeople, com.apple.findmy.finddevices, com.apple.HeartRate, com.apple.SessionTrackerApp, com.apple.NanoWorldClock, com.apple.findmy.finditems, com.apple.Mind, com.apple.NanoOxygenSaturation, com.apple.watchmemojieditor com.apple.NanoSleep com.apple.NanoNowPlaying com.apple.noise com.apple.tincan com.apple.NanoRemote com.apple.NanoAlarm com.apple.private.NanoTimer com.apple.NanoStopwatch I’ve done some testing, but not sure what I’ve found really. I’ve so far identified 3 scenarios. Scenario 1: I have the whitelist profile installed on the iPhone. I download an app that appears in the whitelist from my watch (or at least its iPhone version does). The apps show up on the iPhone automatically and can be launched there. These apps cannot be launched on the watch. Scenario 2: I downloaded a few apps to my watch, that didn’t automatically install on my iPhone at the same time. They were on the whitelist. These ones couldn’t be launched from my Watch. I then downloaded them to the iPhone and they could be launched there (since they were on the whitelist). Scenario 3: A couple of 3rd party apps on the whitelist could be downloaded and launched from the watch with the whitelist installed. It seems as though there are different kinds of Apple Watch app and this is what I’ve read elsewhere. First of all there are Watch-only apps, which do not automatically install a companion iPhone app. Secondly there are companion apps, which when installed from the Watch App Store download their companion app to the iPhone in the background. Someone please correct me - I’m bound to be overlooking something here. So maybe the apps that when installed from Watch automatically install on iPhone and can only be launched from the iPhone have a separate bundle ID for their Watch app which I haven’t included? Apps that are on the whitelist AND do not automatically install an iPhone app AND can be launched from the Watch, include: solstice What3words So maybe these do not need a companion app, but have the same Bundle ID as their iPhone app? However, I’m still not sure why many stock Apple Watch apps are missing from the Watch…. The most obvious answer is that I’ve got their Bundle IDs wrong, but I don’t think I have given I extracted the bundle IDs from the App Store pages of the Apple WatchOS apps. I noticed at this Apple Support page (https://support.apple.com/en-gb/guide/deployment/dep34c5cd30f/1/web/1.0) that there is no mention of whitelisting or blacklisting apps on WatchOS using MDM, yet something definitely happens on the watch when the configuration profile is installed on the iPhone. Furthermore, if I tap on a configuration profile, which comprises a blacklist, on my iPhone it will ask me if I want to install it on the iPhone or Watch. The same pop-up question doesn’t happen when the profile contains a whitelist. All this to say, I’m massively confused as to why I can’t get this working. I’d really appreciate anyone’s advice which is bound to be expert. Thank you

Hello, I am Sergio Sánchez, administrator of NumbuX. We are developing our own MDM. We are already granted as a MDM Vendor. We need to issue the APNs certificate for our MDM for the first time in the Push Certificate portal (identity.apple.com). We are having the error: “invalid signing request” when we upload the signed CSR to identity.apple.com. That is because we do not have the External UUID. Could you please let us know what is our External UUID? Without that, we cannot upload it successfully. We have already compared different signed CSR from other MDM Vendors and all have included the External UUID in the CSR. Please, do not send links, there is not way for us to know our External UUID because it is the first time that we try to issue this APNs. After the first time, we do not need your assitance. Please, let us know our External UUID. Thank you. Kind regards.

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.

ABM has introduced a target date for moving a device from one MDM server to a new one. However, there's nothing in the API for setting that when you use the API to move MDM server Am I missing something or does it just not exist? Thanks Caroline

I’m working on a product that includes TLS inspection capability. TLS inspection using a local MitM requires installing a trusted root certificate which is then used to create masquerade certificates to intercept and forward TLS traffic through the proxy. For manual installation the end user is required to authenticate as an administrator to modify the trust settings on our internal CA’s root certificate. My question concerns the options for enterprise deployment using an MDM. We want the generated root certificate to be unique to each endpoint so that if a private key is compromised it can’t be used to intercept traffic anywhere else. We can install a “certificate trust” configuration profile from the MDM but this requires a base64 encoded string of the root certificate. In effect the MDM needs to obtain the certificate from the endpoint and then send it back in the form of a configuration profile. I’m not aware that MDMs like Jamf can be configured to do this directly so we’re looking for any other mechanism to have macOS trust a locally generated certificate via MDM based on some non endpoint-unique criteria? One option might be to use an external CA with a trusted certificate to sign an intermediate endpoint certificate but this creates a significant risk if the external trusted certificate were ever compromised. Is this a common industry practice? So my question remains is there a better way to trust our per endpoint root certificate via MDM without needing to install a unique per endpoint configuration profile?

We have an office application used internally within our enterprise. The Provisioning Profiles (PP) for the app were about to expire, so we updated the PP and released a new version. However, we've encountered an issue where some users did not update their phones in time. After the app expired, they found it unusable and downloaded the new version, but the newly downloaded app also crashes on launch. Restarting the phone does not resolve the issue, and this primarily occurs on iOS 18.3.2. What could be the cause of this problem, and how should we address it?

We are implementing the Return to Service (RTS) with App Preservation flow. During testing, we were able to successfully fetch the Bootstrap Token as part of the ADE enrollment process. However, when attempting to initiate the Return to Service command with App Preservation enabled, the following error was returned: [ { "ErrorCode": 12089, "ErrorDomain": "MDMErrorDomain", "LocalizedDescription": "Could not erase device.", "USEnglishDescription": "Could not erase device." }, { "ErrorCode": 66002, "ErrorDomain": "MDMBootstrapTokenErrorDomain", "LocalizedDescription": "Failed to generate LAContext for bootstrap token", "USEnglishDescription": "Failed to generate LAContext for bootstrap token" } ] Below is the sample request (with dummy data).

We are encountering a critical issue where an enterprise-signed iOS app crashes immediately after installation on devices running iOS 18.3.2 (22D82). The same app runs fine on other iOS versions (including iOS 18.3.1 and earlier). Issue Summary: After upgrading to iOS 18.3.2, users are unable to launch our enterprise app (Bundle ID: com.kt.MobileDRM). The app installs successfully but crashes immediately upon launch. This issue occurs only on iOS 18.3.2, not on earlier versions or other iPadOS/iOS devices. System Log Snippet: SecKeyVerifySignature failed: Error Domain=NSOSStatusErrorDomain Code=-50 "rsa_pub_crypt failed, ccerr=-7" UserInfo={numberOfErrorsDeep=0, NSDescription=rsa_pub_crypt failed, ccerr=-7} Additional Info: The app is signed with a valid enterprise certificate. No changes were made to the app binary or signing configuration before this issue started. We are not using an IPS file. A similar app (different bundle ID) shows the same behavior on iPadOS 18.3.2 but runs fine on other versions. Questions: Has there been a change in iOS 18.3.2 that affects enterprise certificate validation? Does ccerr=-7 indicate a cryptographic change or stricter signature verification? Are there updated requirements or provisioning profile constraints we should be aware of for iOS 18.3.2? We would greatly appreciate any insights or official guidance regarding this issue. Thank you!
