    I while ago, bought a MacBook Air (A1466) at an auction at a company that went bankrupt. It was password protected but I got the password and thought I could just re-install iOS. I have tried to clear the hard drive with these two methods:


    I now have the admin rights, but when i boot the start screen still says:

    "This computer belongs to (Company Name).

    Is it not possible to COMPLETELY format the hard drive on a Mac?

    If there is no solution to this, changing the hard drive should fix the problem, right? (I.e. there are no other permanent storage location than the hard drive, right?)

    Kind regards

    There is some non-volatile memory (NVRAM) in your Air that stores a small number of parameters and the boot message might be one. The free utility Onyx provides an easy way to change that boot message.

    This isn't something that's stored on the disk. Apple has a program called the Device Enrollment Program (DEP) where an organization gets its devices enrolled in a management system. There's no way to get the computer out of this without the computer being removed by the owning organization. The enrollment status is stored at Apple, not on the computer itself.
