Duplicate softwareupdate.enforcement.specific not allowed?
I am attempting to apply the softwareupdate.enforcement.specific declaration on a device. The first time it is processed it is applied successfully. I then generate a new set of declarations for the device and send a sync command to the device with the new server token. The management.status-subscriptions declaration and the activation.simple declaration are both applied successfully, even though the contain the same content and server token, but a different identifier than the original declarations. For some reason, the softwareupdate.enforcement.specific declaration fails to be applied and the reason is reported as [kSUCoreErrorDDMInvalidDeclarationFailure] New declaration is a duplicate The original softwareupdate.enforcement.specific identifier is not included in the new declaration-items response, only the new identifier. I would expect the device to remove the existing declaration and apply the new one, even if it is a duplicate of a declaration no longer specified for the device. Has anyone else run across this issue?

Can I use maps screenshots with clickable markers in my app?
I would like to inquire if I can use screenshots from maps for specific areas in my application. I plan to add various markers to the screenshots, which can be clicked to identify different types of areas, such as restaurants and bars. Do I need a separate permission for this, and if so, where can I obtain it? Is it possible to implement this, and what copyright considerations do I need to take into account for my business idea?

Is it possible to configure different Check-in API endpoint for MDM and DDM?
The Check-in API is now used for declarative device management in addition to MDM authentication and token updates. We would like to set a different endpoint for DDM requests only than for MDM authentication So is it possible to configure different Check-in API endpoint for MDM and DDM? For example, we would like to split the endpoints as follows Endpoints for MDM authentication and token update yourmdmhost.example.com/checkin Endpoint for DDM yourmdmhost.example.com/ddm-chcekin Check-in API Documentation https://developer.apple.com/documentation/devicemanagement/check-in

Wallpaper fails to be set on an iPhone via the cfgutil command
Hi. I'm trying to use the following command to set a wallpaper on an iPhone : /usr/local/bin/cfgutil -K "/Users/ladmin/Downloads/privateKey.der" -C "/Users/ladmin/Downloads/publicCert.der" --ecid 0xE64120151001E set-wallpaper -s home "/Users/ladmin/Downloads/mickey-iPhone-12-Pro-12-wallpaper.png" The answer is always : --- Summary --- Operation "set-wallpaper" failed on 1 devices. cfgutil: error: An internal error occurred. Unknown service request error. (Domain: ConfigurationUtilityKit.error Code: 100) The same type of command works with an iPad. Apple Configurator 2 can set the wallpaper on the iPhone. Is there something different to do with cfgutil when setting a wallpaper on an iPhone ? Thanks for your insights ! Franck

Using Testflight with a managed Apple ID
Hi all, We've been given the opportunity to beta test an app at my school and we have been asked to download the Test Flight app to enable it to run. Unfortunately it's not possible to use Test Flight with a managed Apple ID. All our staff and pupils' iPads are signed in with a managed Apple ID. It's a shame to pass up this opportunity, but I can't see any way around it... does anyone have any alternatives (apart from creating and using a non-managed Apple ID, which isn't feasible). Thanks in advance, Jacob

Need clarity on "restrict-software-update-require-admin-to-install" setting
In MDM Software Update settings(https://developer.apple.com/documentation/devicemanagement/softwareupdate), there is a key "restrict-software-update-require-admin-to-install" which apparently controls if the standard users are allowed to install apps and software updates. But so far, even if this is set to true, a standard user is able to download apps from Appstore. We noticed that when we publish a pkg to be installed via MDM, then that does not get installed if the above setting is set to true. Please provide clarity on what this setting controls.

ManagedAppDistribution problem with getting the apps
Hello, We are trying to use the Managed App Distribution framework with our mdm following the documentation here : https://developer.apple.com/documentation/managedappdistribution But on the first load we don't get anything, the app keep getting stuck inside the following code without sending an error or getting the managed apps for try await result in ManagedAppLibrary.currentDistributor.availableApps { content = try result.get().map(Content.managedApp) } If we update the list of available managed apps in our mdm, the function execute and so we have all the apps displayed as expected, but if we close and re-open the app it'll again not display anything until we update the managed apps list. How can we fetched our managed apps at anytime and not only when the list is updated ? Why this method seems to be waiting for an update instead of just fetching the available managed apps when we call it ?

When developing a network filter, MDM has configured AllowedSystemExtensions and succeeded, but a reminder still appears when savingToPreferencesWithCompletionHandler
Hi, Team: I developed a network filter and used MDM to issue a description file. By configuring AllowedSystemExtensions, I can avoid the reminder of loading system extensions during installation. However, when savingToPreferencesWithCompletionHandler, I will still be reminded that my network data is monitored. How can I configure MDM to avoid this reminder? And why can I still delete the filter from the network filter conditions even though I configured it in mobileconfig in the following way. NonRemovableFromUISystemExtensions com.mysystemextensionid
