OSX is a thin layer of UNIX with a lot of non-UNIX like stuff. Aqua over X. Self-contained apps over package management (unless you want to count the app store).
I find it more like a broken borked *NIX system than anything.
Neither FreeBSD nor NetBSD have been submitted to the Open Group for certification, and are thus considered "Unix-like". When I say OSX is literally Unix, I mean it has passed certification and can legally use UNIX trademark.
