It’s barely a “feature” that they let you execute arbitrary code on your own hardware.

They don’t provide any source code or documentation (which they easily could) so if want to do literally anything with your “open” device you must first reverse engineer the entire MacOS driver stack like the Asahi project did. Great fun, but it’s a criminal waste of incredibly talented engineer hours.

On top of that, the reason Asahi doesn’t work on M4 and later is that Apple has intentionally modified the ARM core to prevent stock MacOS from running once the hardware is “unlocked,” which makes it way more difficult to reverse engineer.

Bastards.
