We started making the free Apple apps from the Mac App Store available via VPP on our Self Service.
However we're finding that when users are trying to install these they are being prompted for admin credentials for "storedownloadd".
I found this thread which says I need to disable "Require admin password to install or update apps" in Configuration Profiles.
However if I disable that, won't that mean that users will then be able to install apps from other sources such as downloads or USB sticks?
Is there a way to monitor and/or block unauthorised app installations, while still retaining the ability to install VPP apps from Self Service?
Thanks,
Dan Jackson (Senior ITServices Technician).

maybe modify these settings in security prefs pane
