But you must have some strange workflows going - I've been on arch fulltime for 3 years now, and my one breakage was that dash-to-dock didn't play nicely with a new version of gnome.
Frankly - it's a far better experience than the 16inch macbook pro my work issued me - that has problems with fans, problems with lag during zoom calls, problems with accelerated rendering in chrome, issues with wifi and bluetooth connections. I literally call it my crapbook it's so bad.
Right now my sound is broken and it stayed broken even after an update and reboot (That you have to reboot so often is something else that bothers me. Rebooting a Linux/Unix machine feels so wrong).
Your MacBook problems sound like hardware problems. That's not something I would expect from any decent laptop these days.
Compared to the hell that was upgrading Ubuntu versions every couple of years, I'll take Arch's way any day.
I've been running Arch (Endeavor w/KDE now) as a desktop for probably 7 years and I just use my device. I get updates that break small things in KDE, or give me major screen tearing in Firefox once in awhile, but nothing that "breaks so often". It's pretty good and solid in 2021...
I've been running it for 3 years on 4 machines and I've had far less breakage from updates than with my Windows or Mac machines.
Arch lets me engage with the open-source community directly and get fixes to issues faster than more curated OSes like Ubuntu. I have access to more diagnostic information and tools that what Windows provides. And privacy and freedom isn't compromised like on MacOS.
Also, it's gotten really good for games. It plays pretty much everything I've wanted to play, from Stellaris, Cyberpunk 2077, and Humankind.
So, sometimes opinions need updates.
Updates break something so often that I wonder if it somehow is sponsored by other OS developers to make them look good.
