We are trying to create an out of box experience for our students and teachers, and we have done a very good job so far with the iPads. All apps are pushed via Managed Distribution VPP and the tick box "Make app managed if currently installed as unmanaged" is ticked so it can manage the app that are included with the iPad.
I see no such option "Make app managed if currently installed as unmanaged" for the Mac App Store apps, so how do I manage Pages, Numbers, Keynote, Photos, and iMovie on a new machine?
