The tricky point to your needs is getting the app’s menu bar in the top bar. The rest are easy to do with almost all desktop environments. But getting the menu bar on the top bar, I think currently only KDE supports it (with a plugin), and MATE (with another plugin).
However, if you want the general feel of how MacOS 9/X feels, then Gnome with extensions would be your best bet. The rest feel more like simpler Windows, but in a mac skin. Gnome+extensions feel more accurately like a Mac, in terms of overall usability (even if the looks aren’t 100% there). So it depends what you’re after more: the feeling of using a mac, or the exact looks of it.
I’m a woman, and have talked to him via email 2-3 times in the last 20 years. While I’ve met Torvalds, Jobs, and others in the industry when I was living in the Bay Area and working as a tech journalist, I never got to meet RMS – only via email. I think he has social issues, maybe he’s on the autistic side or something similar. I don’t think he understands clearly some of the things he’s saying when it comes to social stuff. He doesn’t get a pass, but at the same time, he’s a bit different as an individual, so that needs to be taken into account. When it comes to software, his heart is in the right place, and in fact, if it was me, I’d be even more strict (or more “Free” – depends how you see it), with GPL.
