Other possibility: bootcamp (native Windows booting) requires something like iBoot starting a CSM or UEFI stub (if the A-SoC doesn't use UEFI - which it might not) to then start the Windows Boot Manager.
I don't actually know the current status of supported Windows firmware loaders, but the most recent information I had was that even on ARM you needed UEFI with Secure Boot.
I am interested in Linux on those Mac ARM desktop machines, probably takes a lot of effort, I don't see Apple making the effort themselves. On the other hand: there is a super small chance that if the A-series SoCs are marketable you'd get no-OS ARM (micro) servers. That'd be pretty cool.
- dahfizz 6y agoI don't think it's an issue like that. You can run windows without secure boot[1], and the windows boot loader can be chain loaded from whatever apple is using if they are not using a standard eufi firmware for whatever reason. At the very least, booting windows is a relatively low effort problem to solve compared to everything else that has to happen to move a whole ecosystem to a new architecture. We can conclude its a low priority for Apple, if it's something they still want to support at all.

Apple doesn't use UEFI on their ARM systems, so it'd be an extra effort indeed.
