I currently run Budgie Desktop (specifically Budgie Ubuntu 18.04 LTS). IIRC, it's based on Gnome (not sure which version) - but it doesn't feel like it. Maybe this isn't what you like - but to me, it's the closest I've come to having a "MacOS"-like interface on my Linux desktop. I've heard a lot of grief people have on MacOS (maybe it's just the people I hang around with?) - but I honestly like it, for the most part. It has its quirks, true. But overall, Apple did a helluva job in making it "just work". Ubuntu Budgie seems to come closest to that experience, without the Apple tax (ie - the hardware - stuff is expensive).
