You need to install at least dozen applications on macOS to come near to features/capabilities of a run of the mill KDE desktop.
GNOME also improved a ton, it seems, but I'm not using it for a long long time.
macOS is lean, but doesn't have the composability and flexibility of Linux at any level. Things designed to add this composability feels bolted on loosely and limited at utility.
Most folks don't want a "go fishing experience", they want a prepared meal.
On the other hand, our parents, partners and non-technical friends use their Linux systems without ever calling us, the venerable yet dumb as a dead tree "Linux folks".
Maybe I'm on an island with everyone which makes this 2%, but these people are real, and they are not compiling things from source or throwing their machines out of windows because of frustration.
They just use their computers, be productive and live happy lives.
I can get my run of the mill KDE desktop to hang at startup by dragging a networked folder with a custom icon to the taskbar, then attempt to log in over a flaky network connection. Or if I attempt to drag too many application icons to it in the Wayland session. Don't get me wrong, I like it, I mean, I use it, but Plasma 5 is still, at best, late beta. My only hope is that, unlike its predecessor, it doesn't get abandoned and rewritten when it gets a semblance of stability.
I never restart KDE on my system, unless I upgrade my kernel, and restart the whole system.
* Unless you use large network mounts, as long as you drag icons one at a time, for a fixed screen resolution, doesn't apply to Wayland, only until the next major rewrite...
*:Unless you use with Wayland backend, since Wayland is not mature enough.
Because my installation both has large network mounts, and I sometimes drag tons* of icons around.
Also I talk with people who use KDE, and report bugs I encounter, or encourage people to report bugs when people I talk encounters them.
I'm pretty beyond "It works in my machine, so PEBKAC" at this point. I think using Linux for 20 years and managing a large fleet for 15 years helped on that front a lot. :-)
Nowadays the only place I still use GNU/Linux as desktop experience, is my aging Asus netbook.
When it dies, it will most likely be replaced by a device from Apple/Google/Microsoft ecosystems.
