Xfce and themetwister get you near exact for mac os or windows visual clones.

KDE can be set up such that a ex-mac-user barely has to re-learn anything.

The difference is that while gnome looks a lot like MacOS, it isn’t exactly like it in terms of layout. An ex-mac-user will look for certain things in certain places, and won’t always find them. (such as power off/restart being up in the left corner)

Meanwhile, the customizability of the KDE desktop means you can manually put the same things in the same places as on MacOS. You can put a krunner search button in the same spot as the spotlight search button. You can make a panel that behaves like the dock, floating and shrinking to fit the number of icons in it. You can have a top panel with a power menu on the left end, and you can display a global menu to the right of it. Even the krunner keybind is the same, and spotlight people tend to pickup krunner like nothing.

Finally, the KDE settings application seems to be the most similar to the modern MacOS settings application.

The big caveat being that the user will need someone who can instruct them with setting this up, or who can set it up for them.

You really haven’t checked lately, then.

I think she’s starting off on the left foot.

I think there’s probably a raccoon guy up near Boston who could use that toothbrush.

Even worse, shés using Windows 11. But a friend of her’s who’s the IT guy for every old lady in the area loves Microsoft products and I can’t do anything against it.

Even proposing to be available to help wasn’t enough…
