been a long time we did not package any Mac apps store...
is it still possible to package Mac apps store to deploy instead of relying on Jamf distribution with VPP ?
Yep, I used to do with the ilife stuff without many problems.
You can do that, though it is likely easier to use https://github.com/maxschlapfer/MacAdminHelpers/tree/master/AppStoreExtract
the Apple ID for our VPP from which we bought all of our licences, doesn't seems to be able to redownload the app from the Mac App Store... its greyed out
Have a read through here for some options.
