Advice on Implementing Active Supervision Mode for Parental Control
I’m looking for advice on implementing an Active Supervision Mode for enhanced parental control. My goal is to restrict access to both iOS system apps and third-party applications to create a safer and more tailored digital experience for my child. Here’s what I’d like to achieve: App Restrictions: Block specific apps (both iOS and third-party) and allow access only to approved ones. Time Limits: Set daily usage limits for individual apps or app categories. Content Filtering: Apply restrictions to block inappropriate content and age-inappropriate apps. Remote Management: Manage these settings remotely from my device for added convenience. Activity Monitoring: View app usage stats or receive alerts for policy violations. I understand that Screen Time on iOS offers basic parental controls, but I’m exploring whether iOS supports more advanced capabilities natively or through additional configurations. I’ve also heard that enrolling a device in Apple Business Manager (ABM) and linking it to an MDM (Mobile Device Management) solution might provide greater control. If this is a viable solution, could anyone provide guidance on: Enrolling a personal or family-owned device into Apple Business Manager. Linking an MDM for configuring app restrictions and monitoring usage. Alternatively, if there are third-party parental control apps that work seamlessly with iOS to achieve these goals, I’d appreciate your recommendations! Thanks in advance for your insights!

Error install in-house App on iPhone 16e
We are going to replace our iPhone SE to iPhone 16e. The issue is that we are unable to install an in-house app on the new iPhone 16e. The app works on the iPhone SE Both phones run on the same iOS version (18.5) Has anyone else experienced the same issue? I initially thought the iPhone 16e was the successor to the iPhone SE

AirPrint MDM Payload is not working as expected
Ref- https://support.apple.com/en-in/guide/deployment/dep3b4cf515/web When we deploy an Payload with identifier "com.apple.airprint" , It will add the deployed printer configurations to printers list in mac. Which additionally needs the mac user to add it from Settings -> Printers -> Add Printer -> (Deployed Printer Configuration will be listed here) Select the printer -> Click Add . Screenshot where user need to add it manually after profile association is attached below. Now the Printer is available to be used ,when an share option in any document is clicked. Why this flow requires multiple to and fro. Can it be able to deploy the printer straight to Printers available List instead of manually adding from the above screenshot

RCS firewall domains & ports
Hi everyone, I’m working as an IT engineer in the cruise industry and need to troubleshoot passenger complaints about Apple’s new RCS messaging feature (introduced with iOS 18). Could someone help confirm which domains and ports iPhones use when they send RCS messages? My firewall team wants specifics: domains (or subdomains) that need whitelisting and the ports involved. Any official or community-sourced info would be super helpful—thanks in advance!

app crashes, but it works normally when another app is installed through MDM.
We install two in-house apps. The first app is installed using the standard in-house method, while the second app is installed via MDM commands. Both apps share the same Team ID and use Keychain sharing to exchange data. However, when the MDM profile is deleted and the second app is removed, the first app intermittently encounters issues and does not function properly. However, when the MDM mobileconfig is reinstalled and the second app is installed again, the first app that was not functioning starts working properly. We have thoroughly reviewed the logs but have not been able to find a solution. Your assistance would be greatly appreciated. We have extracted and attached the device logs that were generated during the error occurrence. log.log

No such module 'DeviceManagement'
I'm working on the companion iOS app for my purpose-built MDM system. when I use the following in a .swift file: import DeviceManagement I get the build issue: No such module 'DeviceManagement' When I attempt to add the framework in the Frameworks, Libraries, and Embedded Content settings, DeviceManagement doesn't even show up in the available frameworks. Alll the documentation I can find suggests that is the correct framework to import, but I'm new to this and not sure if I'm just missing something. Some AI help is suggesting that the culprit might be v16.x of Xcode, but I don't know enough to prove that correct or not. Any ideas on why Xcode believes there is no such module? Is there documentation that might help me learn how to make that framework available for my project?

allowCamera on Unsupervised devices
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?

User access to Apple store with user affinity MDM profile
Hello We have devices setup with in ABM and managed with Intune. Having only ever setup shared iPad's, we have a new request with managing iPhone's. The customer wants the iPhone's managed, but users enabled to purchase apps for the app store using their own credit card (or Apple ID) These are not BYOD devices and federated sign is not an option at this time. Can this be done with example User affinity profiles? Many thanks

AES Encryption Breaks Enrollment vs. 3DES
We are in the process of replacing the TripleDES algorithm with AES in our MDM solution. However, after switching the encryption algorithm, we encountered the following error on Apple devices during enrollment: Error: "-26275 error decrypting response payload (mdmclient(SCEP))" Do Apple devices support AES encryption during the enrollment process, or are there any known limitations that prevent its use? Technical Details: During enrollment, when the device attempts to install the Management Profile, it requests the MDM server to retrieve the device certificate from the SCEP URL. We send the certificate by creating Enveloped CMS content, using TripleDES as the algorithm identifier. If we switch the algorithm to AES, we observe the error mentioned above. We are also using TripleDES when preparing the CMS content for the enrollment profile, which works without issues.

I'm trying to get the "App and Book Information" of the custom app, but the result is empty.
I'm looking at the Apple official document below and getting the app's information. https://developer.apple.com/documentation/devicemanagement/getting-app-and-book-information-legacy However, I couldn't get the custom app's information for a few days ago. The result item is empty. This is a URL that is normally viewed. https://uclient-api.itunes.apple.com/WebObjects/MZStorePlatform.woa/wa/lookup?version=2&p=mdm-lockup&caller=MDM&platform=volumestore&cc=jp&id=1202716089 This is the URL that gives an empty response to the result. https://uclient-api.itunes.apple.com/WebObjects/MZStorePlatform.woa/wa/lookup?version=2&p=mdm-lockup&caller=MDM&platform=volumestore&cc=jp&id=1556411142 In ABM/ASM, the number of applications used and the number of available applications are all viewed normally. Is there anything else I can check? Please reply. Thank you.

Questions about MDM command "DeviceLock"
Hi, I have a couple of questions about how to proceed and prepare the implementation for the DeviceLock MDM command for macOS in a secure and proper manner. https://developer.apple.com/documentation/devicemanagement/device-lock-command In documentation "PIN" is "(string) The six-character PIN for Find My. This value is available in macOS 10.8 and later." - is this the PIN that is used to unlock the device? Is there any video online that I can see how the process would look like for the end user with locking and unlocking a device? What should be done before sending a DeviceLock command? What should be done to safely test the command without bricking a device. How to unlock a device that was locked with a DeviceLock command? Is there any Unlock command or can the user unlock device with the provided PIN earlier? Thank you for any help!

Device touch screen not responding after restart
On devices running iOS 18+, when a web app kiosk policy is pushed via an MDM and the device is restarted. The touch screen doesn't respond on the device. So the device is currently in a brick state. Since we can't enter the password we can't get the logs from the device and it is even hard to recover the device. On restart the device isn't connecting to the internet so it isn't possible to remove the kiosk policy as well. This only happens on devices running iOS 18+ and with web app kiosk profile.

Recover device enrolled email from any iOS device for an enterprise app?
Is the possibility of programmatically recovering the enrolled email address associated with an iPad. We are currently working on a project that requires us to retrieve this information for our enrolled devices. Could you please provide guidance or documentation on how we can achieve this programmatically? Specifically, we are interested in any APIs or frameworks that Apple provides for this purpose, as well as any necessary permissions or configurations that need to be in place.
