About Mac OS X

What's the definition of Mac OS X (or simply OS X)? It is a UI operating system (the tenth major version) based on Unix developed by Apple Inc. and used exclusively on current Macintosh computers, including Mac desktops (i.e., iMac, Mac Mini, Mac Pro) and Mac laptop (i.e., MacBook Air, MacBook Pro, and MacBook Pro With Retina). It was the successor to Mac OS 9, released in 1999, the final release of the "classic" Mac OS, which had been Apple's primary operating system since 1984.
