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.
