If you want to use Linux for the tools, then just use a VM.

But if you want full control over your hardware... Apple isn't the way to go. I'm not even sure what the "OS of our choice" means when we're talking about a custom-designed SoC. The amount of reverse-engineering required to get any other OS to work would be staggering, no?

If you want to run a custom OS natively, you need to buy a laptop with a commodity chip, not a custom one. Fortunately, there are tons of them.

ARM actually has a defined architecture and UEFI equivalent, which would have worked wonders here.

If Apple had decided to support it, that is.
