My current job has me using MacOS on an M3 Pro Macbook and I find it barely tolerable compared to KDE. Usually when I want to do something new or change some configuration, either there is no way to do it, or it's hidden behind some key combination that I never would have guessed. I would describe the overall feel of MacOS as "syrupy." When using the mouse or typing, there is almost always some kind of barely-perceptible latency. Nothing is ever crisp and instant. (This isn't specific to this machine, it feels the same way on every Mac I've borrowed.) It's sort of like someone decided that the only way to make it smooth was to also make it slow.
In fact one of the front page articles today is literally calling macOS “ugly” in the title.
Plasma can be configured to rhyme with macOS' GUI. Not as in shitty macOS themes, but button placement, docks, global menus, widgets, Spotlight, Stage Manager, hot corners, keyboard shortcuts, Preview in Finder, etc.
I have Plasma configured to take advantage of my decade+ of macOS muscle memory without having to put up with Finder and the abysmal task-switching and window management experience on macOS.
Whenever I have to use macOS, I am reminded of how much better Plasma is. I'd might even buy a Mac again if I could use it instead of the default UI.
but it feels a bit of peer-pressure/cool-factor, people used to like how Mac OS look but after Tahoe, I feel like most people don't.
To be honest, I am on mac right now but I really like Niri/Hyprland and to a degree KDE as well. I definitely feel like those were immensely more customizable and I miss that customizability, even if some people might use that customizability to make it look like MacOS default.
