Mac OSX is also a distribution, containing (formerly mostly GNU and now mostly BSD) third-party utilities. However, the surface area that Mac OSX tries to cover in terms of real UNIX utilities is getting smaller and smaller. It's almost ;) as if Apple doesn't care if real UNIX people prefer their laptops anymore. Apple has moved on, to a bigger and far less demanding market: "real" people who have never heard of the artist formerly known as UNIX.
