Has anybody personally tried this? I really want to buy one of these MacBooks. Probably a 13" with the Touchbar. I've never purchased a Mac before. I have 3 laptops (2 Linux, 1 windows), and a Windows desktop. I think this particular Mac would be a stellar daily driver though. It just needs Linux!
I own a 15’ touch bar and I installed Kali linux. There have been a lot of driver issues for my Mac. I managed to get touch bar to work, the controls on touch bar are screen brightness, keyboard backlit, volume and music control. However, NONE of those work because of driver issue ( no sound card driver so music and volume don’t work, no keyboard driver so backlit doesn’t work, etc.)
Best chance you have is a rolling release with the latest kernel. I am using Manjaro mostly (not on my macs though) and it does a nice job dealing with newer hardware. Any Arch should do.
