I will double check on High Sierra and El Capitan. So far I only tested qemu-system-aarch64 and it worked on Mojave, but did not test elsewhere (my aim was to get my osdev going, only).
I have a range of older osx machines (not as old as 10.6 though), so will put it through some rounds. Will post here with results.
