Apple doing some minimal work to support their own hardware with Linux might bring them some new business. And it sounds like it shouldn't even be that much work. Mainly just documenting their hardware would be good enough to bootstrap that.

For developers, macs are just really nice hardware and there are not a whole lot of similarly nice, Linux friendly laptops out there. Most of them seem to be compromises between being noisy, not having great screens, keyboards, and touchpads, mediocre performance, etc.

Typing this on a Samsung Galaxy Book with a meh screen, meh touch pad, alright keyboard, and unimpressive performance. It runs Manjaro. I do miss having a nice screen and input options. I'm actually using a wireless mouse for the first time in a decade plus. Never needed one with a mac.
