I think you gotta actually try to use it as your main OS to hit some of the snags. It can browse the web just fine, but I couldn't get sshfs working. There were strange global keyboard shortcuts, rarely actually used, breaking common shortcuts like ctrl + left/right arrow (fixable, but not super trivially). Homebrew is better than nothing but pretty jank in practice. Repeatedly I'd see graphical stuff installed from there was declared broken and I was pressured to delete it, or I'd have to reapprove some security thing after an update and add it back to the dock. Just lots of friction everywhere. I couldn't seem to consistently keep windows the same size and in the same spots, but they were almost right which made it more maddening. It was like they'd slide around slightly after a reboot or changing monitors. Speaking of monitors, low DPI fonts on macOS look inexcusably horrible. The same monitors I've used for years displaying similar stuff just looked absolutely awful on macOS compared to GNU/Linux. I never was able to fix this. I suspect in their pushing of hidpi and their own hardware they've mangled and abandoned classic resolutions and fonts. This one can barely even be discussed online because everyone's drank the hidpi koolaid and will call you poor or perverse or something. There was also a horribly annoying issue when trying to use a MBP like a desktop. If left inactive too long, I couldn't seem to wake and unlock it with my external keyboard and mouse connected to a dock. I had to open the laptop lid, log in there, re-allow my input devices, then close the lid. I also had to repeatedly go through that wizard that tries to identify your keyboard layout by having you press the key beside each shift key, as if it'd never seen my keyboard before. I have used this same keyboard on GNU/Linux and Windows, there's no equivalent to that needed, I don't really get it.

It's all bad enough that I have a very expensive machine collecting dust until Asahi supports multi-monitors fully. It was a good reminder of how important software and familiarity is, and how much you stand to lose by just chasing after better specs at all costs. I really just wanted my exact usual setup with a spec bump (which I eventually got when I upgraded from my T440p to a T14 Gen 5).

As for positives of macOS... I like the unix-y bits, what's left of them. If I have to retrieve pictures off an old Mac for someone's funeral board, the find command I know and love is there, and a familiar shell as well. I just can't live in macOS full time. It's not good enough for me.
