unfortunately, contrarily to popular belief, you cannot run Linux natively on recent macbooks (m4) today.
That doesn’t really affect what I’m saying though. Yes, support capped out with the M2, but you can still observe the properties of efficiency on there.
You can run Linux on a MacBook Pro and get similar power efficiency.
What? No. Asahi is spectacular for what it accomplished, but battery life is still far worse than macOS.
I am not saying that it is only software. It's everything from hardware to a gazillion optimizations in macOS.
You can run Linux on a MacBook Pro and get similar power efficiency.
Or run third party apps on macOS and similarly get good efficiency.
