I tried to install FreeBSD on my SSD on my mac since I was guessing they should be working, but there no drivers for macos and I decided that I should go back at Big Sur. I formatted the disk via the freebsd installer to the ZFS file system, but when I opened Apple's BIOS, I wasnt able to see the SSD there, therefore I could not go back to macos.
Is there a way to fix that? I am guessing that the format of the disk is unknown to the bios so I probably need to format it in a type that it "understands" it so to say.
By the way, I tried both ubuntu and freebsd and they are working, they could detect the SSD and install their components.
