Followed the instructions to a T and they worked for me. Now dual-booting macOS High Sierra and Linux Mint on a Late-2011 15” MBP. Thanks for helping to give it a new lease on life!
Doesn't work at all for me. I'm on an m3, the flash process completes successfully but the mac doesn't see the stick as either readable or bootable. The only option i get is to initialise it. Gonna try another stick
Same for me, only shows P4, the other partition! wonder if to do with drive on Mac specified as apfs, unfortunately will have to give it up and back to VM.
