================================================================================== Installing on a FAT filesystem does not work at all. grub-install actually refuses the installation if the target directory for --macppc-directory is not an HFS/HFS+ filesystem.
Oh it works - or let's say it worked for me back when I tested it in 2018 on a Mac mini G4 and a 11,2 Power Mac G5. According to the relevant line in my PR ([1]) you have to omit `--macppc-directory` from the `grub-install` command.
