Yes it is MacOS with the dock hidden. And without window buttons. And they are not on the left and not damn colorblind unfriendly.
I mean the top bar is the exact same, the app drawer, the workspaces. The quicksettings. They just removed even more stuff.
Edit: there are many things about them that are different, but the overall design seems similar to me. I think GNOME is way more usable and makes more sense. But still, having a top bar already is kinda odd and I think using that already makes you “macOS like”.
