“How do you describe Mac OS X? Batteries included!”
Mac OS X is a Completely Redesigned implementation of the Macintosh operating system based on the BSD UNIX operating system. UNIX is an advanced multi-platform operating system that offers advanced features such as enhanced networking, high performance, and security. By focusing around the UNIX environment, the Macintosh now arguably becomes the most powerful consumer computer available today. It has so many built-in features now that you may well want for nothing more in an operating system. Simply, your Macintosh is still a Macintosh with the added benefit of being able to do anything that UNIX can do.
