Don’t know how many Mac admins out there are actually using Server.app’s Profile Manager for MDM, but I found a weird little quirk to it that’s weirder than the other weird quirks about it.
If you disallow renaming the device by unchecking the box in iOS Restrictions, it doesn’t just restrict users on the iPad from renaming the device—it also restricts Profile Manager itself from renaming the device!
So if you have some renaming you want to do on supervised devices using Profile Manager, you may want to uncheck that box. Very odd…
