I tred both as around this, ie I put a Linux Mint HDD into the machine, it just sat looking at me. Then I wanted to do a live Linux Mint USB boot up but cannot find a way to change the boot sequence in the apple equivalent of a BIOS, called EFI.
I will not be spending any more time on this, my task was to remove all prsonal data, which I have done.
