Pop OS, combined with "Toshy" for using Mac keyboard shortcuts. I find this is a really comprehensive translation of Mac shortcuts, even cmd+shift+{} works for moving between tabs. I use my Keychron keyboard in Mac mode retaining all the same muscle memory.

It was working quite perfectly with 22.04 but there are some caveats with the recent Pop OS "Cosmos" version, I can't find the shortcut to cycle between instances of the same application (cmd + `) and in general the OS is a little buggy and functionality can be quite sparse in some applications like you can't rearrange tabs in their terminal yet and it didn't even have "open new tab to the same folder I'm in" until recently. However the trajectory they're on is a Mac-like system-wide consistency and thoughtfulness, it's just early-stage.

Awesome, I'll take a look at Toshy, too. I was looking into PopOS or CachyOS (with Cosmic). There seems to be such a vast amount of Linux distros and window managers than I remember from a good 5-10 years ago.

Everything seems to be tied to a subscription now on the Windows/Mac side in some way, its been very off putting for me.

I really like being able to map the Mac key bindings.

I run Zorin on an old Mac and I am pleased with it.
