Videos Show How to Make KDE, GNOME, XFCE, Cinnamon Look Like macOS Big Sur

Why?! Why would someone want to do this?!

One big reason why this is helpful, regardless of how one feels about copying Apple design or putting lipstick on a given Linux desktop design, etc.:

If you aren't a graphic designer / don't know much about graphic design, you can often use this kind of tutorial to get a more preferred look / feel. Something more in the general direction of the graphical style you like.

Then you can customize from there if you want. Remove Apple-specific icons, and so on.

So it can be a helpful workaround for "IDK how graphic design works but I want something more polished than my distro maintainer offers".

But a LOT of really amazing themers / UI people started out with tutorials like these. It's a thing going back to the early 2000s at least. Those people learned not just how to copy designs, but they observed the type of changes they were making, and developed a refined feel for the elements & principles of design.

(Personally I remember lots of lessons in comparing before/after. For example coming from KDE, and thinking "oh, I see now--KDE puts about 4-5 layers of outlines around UI elements, and that's kind of awkward".)
