Freshly DEP enrolled MacBook Air, which had to be recovery mode re-imaged because it would not pick up DEP, we received the "needs to repair your library" loop upon first login to management account created by DEP.
Enrolling same model, fresh out of box. Took forever for DEP enrollment (wifi, hidden SSID).
Not sure if the issue is strictly with these MacBook Airs or what, but have never had this issue with any other recent new hardware.
Have not ruled out the wireless networks here and recent network changes being made, but that would not account for the "need to repair library" dealio
