I was going on the fact that the T2 has a “No Security” option for its Secure Boot config, while according to Apple Support the Apple Silicon ones (I don’t have one) only offer “Full” or “Reduced” security, which would still require signing: Change security settings on the startup disk of a Mac with Apple silicon
Dunno how the Asahi folks are planning on doing it, but they do indeed say there is no bootlock 🤔
Update: according to the Asahi docs, I seem to understand that Apple Silicon devices allow creating some sort of “OS containers” that can be chosen to boot from separately from the Mac OS one, and in such a custom container the security can be set to “permissive” limited to that container: github.com/…/Open-OS-Ecosystem-on-Apple-Silicon-M…Interesting.
