Re: It works until it is blocked
Apple don’t care what software you run on their computers because you already forked over your $$$ and they aren’t as reliant on App Store income on macOS like iOS.
What they don’t like is you running macOS on non-Apple hardware as then they make $0.
Whilst they might not actively help a Linux development on their hardware, they won’t cry any tears if you choose to buy an Apple device to run another OS on. I know they certainly would have made a few laptop sales in the past for Windows customers because of the battery and build quality etc.
