Mobile Manager got an update today.
Fixes:
Changed the default value of Allow enabling restrictions under Policies > Restrictions to True. This matches the default value on iOS devices.
Corrected an issue that was causing SSL certificates to not deploy to OS X devices via Mobile Manager.
Corrected an issue that would not allow Groups to be deleted when the default language for Mobile Manager was changed to certain languages.
Fixed an issue with creating Admins that displayed an error message upon saving.
