    What is the model / year of the MacBook Pro and do you have a backup ?

    If it's from 2018 or later, it has a T2 chip and you need to go to an Apple service center with proof of ownership so Apple can unlock it.

    Note - If people have a Mac with a T2 chip, don't erase the drive or at least allow booting from an external drive first.

    So if one wants to sell a 2019 mbp with a t2 chip, is there a different procedure to follow that doesn’t involve CMD R and disk util, disk erase, and reload?

    I'm not sure what the procedure should be now.

    I would at a minimum disable the T2 security that prevents booting from an external drive.

    That's no longer true. It was true the first month they were released...
    Source: I created the original post regarding that issue, and wiped my new 2019 MacBook Pro a month ago.
