Which one? The Mac changes with every iteration of the os. Some might argue not always for the better.

ElementaryOS was kinda polite in a modern mac-like way last time I looked.

Or are you referring to mac os 7 style? There was a project awhile ago to implement finder-like file windows. Forgotten its name.

Why? When you can use MacOS itself?

That's a bit like using black-face instead of hiring real black actors.

Unless you own Apple hardware you can't really.

I switched to Mac as my daily driver precisely because of the Desktop Environment being a nice place to live, other than that I prefer the features I get in Linux (Vulkan API, Containers, GNU tools).

Gnome 40 is close but still, MacOS's (not perfect) DE gets more right. I would love to have my macOS Catalina DE in Linux

Hmm. I wonder if it would be easier to bring the MacOS features to Linux, or the Linux features to MacOS.

Theoretically, it's doable because both systems are 'unix-like' under the hood. It really boils down to it being 'an itch that somebody needs to scratch'. It could be you. <grin>

It would be easier to bring the features to Linux than MacOS as MacOS lacks modern APIs for things like graphics rendering and kernel support for containerisation.

I thought about it, writing a DE targeting Wayland replicating MacOS. There are lots of considerations though, like how to ensure apps written with QT or GTK would render correctly, put their menu in the right place and all that.

I am wholly unqualified for such a task, though I have the enthusiasm for it.

Why should there be?
