Last year we created a PreStage Enrollment to do some testing, and had assigned it just to a few Macs we were testing with. At some point the Enrollment profile got the option ticked to automatically assign all new devices. So, apparently this summer when we processed our 1100 new MacBooks, they were all assigned to this PreStage Enrollment profile.
For prepping Macs we are still imaging with Casper Imaging and enrolling as part of the imaging process. We are not quite to the point of utilizing the PreStage Enrollment. However, now the 50-70 staff devices we have handed out prior to school starting are getting the DEP popup about wanting to enroll. If the staff member continues on with the enroll process either 1) the existing profiles are removed thus removing the WiFi profile stopping the enrollment, or 2) they get an error that the Mac is already enrolled in and MDM and can't be enrolled in two MDMs at one time.
I tried unassigning all of the Macs from the PreStage Enrollment, but still would get that popup. Not I have completely deleted the PreStage Enrollment policy in the JSS, but we are still seeing the popup come up.
What can be done to eliminate this popup from devices that are already enrolled? My next thought was to go out to Apple School Manager and Unassign all of our serial numbers, but that seemed drastic.
Thanks, Tim
