I will say that power efficiency is one of the places Asahi is still behind compared to native OSX performance. I don't fault the path the developers are taking. They first focused on getting a stable OS: done. Then worked to get a number of the very unique hardware devices addressable and functional: mostly done. And then worked to upstream all of those things into the kernel, where they have also had success after success.

The current power efficency is workable for me. I can get about 6 hours usable out of the battery and I only charge to 80% regularly (which I like the OS supports a charge limit). One other drawback is the lack of deep sleep or hibernation. Since its Mac hardware it doesn't follow the ACPI convention so S4 hibernation which I usually use on PC hardware isn't an option.

Still, the hardware is excellent. The performance is excellent. The most recent M series CPU that is fully supported is M2 (M3 support is available in alpha channels, but I'm not that adventurous), which means the "flagship" experience is very affordable by buying pre-owned hardware (don't get less than 16GB RAM, I got a 24GB Macbook Air and am happy I did, 256GB SSD is usable, but "cozy". I'd recommend at least 512GB).

I'm very happy with the Asahi experience, and really like having the option to fall back to OSX if needed for some kind of commercial hardware or so compatibility. I've only had to do that twice and that was to watch streaming services on vacation.

BTW, There's an Asahi Lemmy community which has a small following.

There's also an ARM Linux Lemmy community but its not well visited.
