@walt You can create a Smart Group with the "Enrollment Method PreStage enrollment" criteria using the "is not" operator to find out what Macs aren't in your PreStage Enrollment(s)
hm, when I created a smart group "Manual enrollments", Enrollment Method PreStage enrollment 'is not' DEP, it does not show the manually configure or User-initiated/invite enrollments. it does exclude the DEP prestage Macs.
@walt Interesting that no PreStage Enrollment info for a Mac doesn't match that criteria, but as someone famous once said to me, there's lots of ways to shave a yak. Try this:
Create a new smart group named "DEP Enrollments", Enrollment Method PreStage enrollment 'is' DEP
Change your "Manual enrollments" smart group criteria to Computer Group 'not member of' DEP Enrollments
The "Manual enrollments" smart group will now contain any Mac that didn't match the "DEP Enrollments" criteria
that config works, I also was able to create a smart group, criteria Enrolled via DEP is No which showed the manually enrolled Macs as well.
@walt The Enrolled via DEP criteria sounds like the better approach to shaving that yak
