happy (again)
what is darwin? Is it another version of unix?

Ex... You are at a computer show, and you ask someone what OS they use, and they say Unix. You ask someone else, and they Linux. They ask you what your OS is. Can you say Darwin? Is Darwin at the same level?
 
If something is true "Unix" then it abides by what The Open Group say. Other operating systems, like Linux, are "Unix-like" as they don't fully fall into what The Open Group say is Unix (since they are the current holders of the trademark that is Unix).

So to answer your question, if someone says just Unix, they aren't technically answering the question, as that could mean any number of OS's. Darwin is a mach/BSD hybrid, and is at least Unix-like (Apple is a member of The Open Group, so maybe Darwin is true Unix as well, not sure).
 
So... Mac OS X is UNIX according to The Open Group. And so is Darwin, which are the open source parts of Mac OS X (basically everything excluding all the GUI stuff).

You can very well say you're using UNIX and be technically correct. But if anyone says he does, ask him what 'flavour' he uses. Solaris? Irix? HP-UX? AIX? Mac OS X? :) 'Or just Linux'. :)

From a knowledge point of view it doesn't matter whether you're using a true UNIX or Linux, but Mac OS X certainly doesn't certify you as a UNIX guru. Unless you really are a terminal cowboy, have your Users folder on a different partition, implement your own Darwin kernel in OS X, write .kexts and so on. :p

I for my part am a Mac OS X user. Not a UNIX guru.
