There's a boot manager technically accessible via a keyboard combo while starting up a Mac, but it's nicer to have an actual boot manager that understands other OSes exist.

Fix after a macOS update or such wipes it out

Of course, like other crappy OSes like #Windows, #macOS will likely clobber this install when it installs any updates itself. So the main reason this wiki page exists is for @keithzg to easily find the steps to fix that, or any other namely, from a #macOS terminal:

mkdir /Volumes/ESP
mount -t msdos /dev/disk0s1 /Volumes/ESP
bless --mount /Volumes/ESP --setBoot --file /Volumes/ESP/EFI/REFIND/refind_x64.efi --shortform
