I believe it is a CPU issue, older CPUs can’t, newer can.
Every LaCie drive I google is thunderbolt 3. I need 1 or 2.
Spelunking I found a very interesting (and unlikely) site that delves deeply into technical stuff like booting.
But they raise the issue of codesigning,
and the potential to codesign an executable which would have a major impact on macports
Again thanks to the list for indulging OT stuff
