Interesting, although the open sourcing of swift feels more obvious than arm macs. Bitcode and app thinning are currently ios+watchos only. I think it sounds more likely for ios and especially the watch changing architectures in the future rather than a non-x86/64 osx. But I'm probably wrong.

What would be the selling points for an ARM MAC? Access to the iOS app store software library? (unlikely) Better battery usage? (maybe) Super cheap devices? (un-apple-like)

Changing archs has been done before but I don't see a rosetta for intel apps running smoothly on arm. Virtualizing windows and linux is another killer app for intel macs that would be missed for some.

You're giving up a lot of performance for that battery life, however, and I think it's probably premature to even think about ARM Macintosh for three years at the least, if ever.

You control the whole tech stack thus a good selling point would be a longer lasting battery.

Perhaps it's also a shot in front of Intel's bow.
