This almost makes me want to try a Mac. Everyone is copying them, they must be pretty good, right?
I just miss it when my apps had main menus, and dialog windows instead of transitions, and it didn't feel like every window was a browser even when they weren't electron apps... and I miss the window borders, and the colored icons, and when themes weren't just light or dark and...
You'll be disappointed. Even Apple isn't adhering to its own Human Interface Guidelines anymore. It might be the least bad option of the current desktop environments, but that doesn't mean much.
