Is Apple's Device Enrollment Program (DEP) tied into the OSX Installer, Hard Drive or Machine?

Question

My case is I bought a macbook off eBay, reformated the SSD inside it to High Sierra then transfered the SSD to an older Macbook and that's when I started getting the DEP notifications. The older Macbook previously never had the notifications.

So my guess is the DEP either came from the OSX installer I used or the SSD?

Answer 1

DEP follows the machine, not the installer or drive.

Apple doesn’t have a neat article for this like it does for iPhone or Apple Watch.
