I am always downloading widgets and free programs for Mac, almost the same I use on windows PC's.

Yes, OSX is Darwin. Darwin is a descendant of 4.2BSD-Lite, the last UNIX developed by The University of California @ Berkeley (to remove all AT&T code from Berkeley UNIX). Darwin still conforms to most of the POSIX standard, and is therefore, a close UNIX clone.
