Need Assistance with Removing MDM Profile and DEP Enrollment

Sorry but again, there is nothing Apple nor anyone else can do about this. Only the organization that installed the MDM can help. If they cannot or will not, then those systems are now useless. I understand the need and frustration, but that's how those sorts of systems are designed, to control the Mac and keep it secure, so removal outside of the MDM is almost never possible. I doubt that even the company that makes that MDM could or would help since that would be a serious violation of security.

Stay safe, and best regards.

I have recently received a MacBook that is currently enrolled in the Device Enrollment Program (DEP) and is managed through an MDM profile by Idaho National Laboratory. However, I have no affiliation with this organization and am having difficulties removing the MDM profile from my device.

Is there any way to remove the device from DEP and disable the MDM profile without the involvement of the original managing organization?

No, there is not. You need to contact the person/vendor from whom you received the Mac, and they need to have the organization unenroll the device from MDM. The whole point of MDM is device management and protection from unauthorized use. If the Mac was properly prepared for transfer by the owner for an authorized disposition, MDM would have been removed.

It is possible to obtain Apple's assistance in removing MDM but only if you can prove that you are the original owner of the device (i.e., you need to provide proof of purchase showing your name and the device's serial number). Since you 'received' this Mac, presumably you will not be able to do that.

It's quite possible that this Mac is stolen property. In any case, as neuroanatomist said, without the cooperation of the organization that installed the MDM, there's nothing you can do. Return the Mac to the place or person you got it from, and they cannot or are unwilling to get the MDM removed, then if you paid anything for it, get your money back. The Mac is useless to you as it is now.

Regards.
