Activation Lock didn't clear: --1008F error.
Recently I received a donation of a MacBook Pro model A-1990. The owner wanted the content erased and using her Apple ID I ran the erase option from the recovery menu. When the internet recovery download process completes, the error code -1008F displays. I have removed the computer from the list of devices in her iCloud "Find My" page, but continue to see the same error when I attempt recovery [Option-command-R]. The computer will not boot from external media.
I want to install Linux Mint from external media. Any suggestions?
MacBook Pro (2017 – 2020)
