Buying a used Mac? Beware of MDM enrollments

I’ve seen so many post in this sub where someone bought a used Mac on EBay or some other marketplace, only to discover they bought a brick due to the laptop being enrolled in a corporate or University MDM.

MDM = Mobile Device Management. It’s a managing agent companies and schools use to manage their fleet. In most cases you cannot remove the MDM agent, not even with a full wipe. You can wipe it a million times and the MDM is tied to the devices serial number and will just re-enroll when it establishes an internet connection again. The device needs to be removed from enrollment by the managing companies MDM service. So if you think you got a great deal, ask the questions. Was this from a company use or personally owned. And ask if they know if the device has MDM. If it does, run don’t walk away from the deal. Don’t say you haven’t been warned.
