No surprises here. Just like the lockdown on iPhone screen and part replacements, Macbooks suffer from the same Apple’s anti-repair and anti-consumer bullshit. Battery glued, ssd soldered in and can’t even swap parts with other official parts. 6000$ laptop and you don’t even own it.
I have a 2011 MacBook Air and it isn’t supported anymore but I’ve put Fedora Linux on it. It’s snappy and the track pad is still fantastic.
My 2008 MBP is still running with a Linux distro. It was more for the fun than the usability with the Core2duo and 2go of ram.
