go there

the theory here is that OpenBSD's installer overwrote bootaa64.efi in BOOT. And that it really is grub. First, store away the current bootaa64.efi
tingo@Torfinns-MacBook-Air EFI % mkdir openbsd tingo@Torfinns-MacBook-Air EFI % cp -v BOOT/bootaa64.efi openbsd BOOT/bootaa64.efi -> openbsd/bootaa64.efi
then copy back grubaa64.efi to bootaa64.efi
tingo@Torfinns-MacBook-Air EFI % cp fedora/grubaa64.efi BOOT/bootaa64.efi
then cd back and unmount
tingo@Torfinns-MacBook-Air EFI % cd tingo@Torfinns-MacBook-Air ~ % sudo diskutil umount disk0s4 Password: Volume EFI - FEDOR on disk0s4 unmounted
Yes - that worked.
