You also can't sell it to a school and have them add it to their DEP without you being an Authorized Apple Reseller. It can't be added back at all as far as I know. Hopefully the DEP Guide will answer this question in a convincing manner, so I'm on to that. I'm just saying that so far, I've been unable to uncover any evidence that it's not true. I don't know that this is true, and am not claiming that it is. If there is no concrete barrier (such as for instance the need to physically access the machine) then everybody who owns a Mac that was previously enrolled in DEP would seem to be wide open to losing control of their Mac at any moment. I'm trying to determine whether I now have to trust a random collection strangers at Apple and the college, or whether there is some concrete barrier to my re-enrollment in DEP. Would you give me, a total stranger on the Internet, your Mac UUID or serial number based on my assurance that I'm a nice guy who knows what I'm doing? Nobody would do this, right? Yes, I know this sounds paranoid, but please consider this. If the college can remove me from DEP simply by taking my UUID or serial number off a list, what's to stop them from adding those numbers back to the list at some future date? Ryan, here's the question no one has been able to answer for me yet. Thank you very much for the DEP Guide sswartz, this is very useful.
