MacOS was never fun. I've been using MacOS at work for five years and it's never been fun nor intuitive. I always explained this to myself "that's because I grew up with Windows" but three months ago I switched to KDE on my private machine and it's miles ahead of MacOS. Just a week ago I got a new company Macbook and the UX is even clunkier than before. Shit just doesn't work.

I feel like the older versions had much more of a personality. OS 8-9, OS X (10.0-10.9). Once they (and Windows) started with flat design (which was over 10 years ago!) everything just converged and now all UIs look very similar to each other. MacOS Big Sur and Tahoe look quite similar to various 3rd party KDE and Gnome skins that predate them.
