I have run into an issue with brand new Mac with Big Sur. They will not pick up the management profile from our Pre-Stage Enrollment so it will not prompt the user to acknowledge that the device is managed by our district and install the profile. I have checked our DEP and made sure the Macs are scoped in our Pre-Stage Enrollment like I have done a thousand times before but these new Macs will not pick up the profile.
This is a known issue, but I've not yet gotten a solid answer as to the cause from either Apple of Jamf. You'll need to erase the drive and re-install macOS from Recovery. Alternatively, if this is happening on MacBook Air's, we have been told by Jamf and Apple to connect power adapter to the machines and let them sit for 2 hours, not turned on, so that the battery gets charged.
