The way Unix-derivatives like Mac OSX, Solaris, HPUX, BSD etc work, is that
their companies bought a licence from Digital (the original creator of Unix)
to use the Unix kernel sourcecode but modify and expand the system around it
to make good use of the computer's specifics.
Maurits:
Just a small correction. Unix was Developed by Bell Labs,
a division of AT&T at the time. Digital (DEC) was a a major
promoter of Unix in the early days. The University of
California, Berkley - took over a version of Unix way back
when - and that version is known as BSD Unix. That is what
Apple's OS X is built on top of.
Sorry for the correction
