yeah, i've ditched the iPhone. GrapheneOS. i don't have an Apple ID. everything is pretty much open source. Flashed an old iMac with Pop_OS. Didn't work. Ubuntu for now. Just takes time.
Hopefully I get there.
With my hair in tact.

I've had really good luck with https://mxlinux.org/ on older Apple hardware. I have a 2014 MB Air that is still running like a champ with it.
Install mbpfan (it's in the repos) and you're good to go!
Godspeed, sir. Check out 2-3 year old ThinkPad Carbon X1s. Great bang for the buck, and most run Linux nicely.
