Background

OS X is the tenth major iteration of the Mac OS series of operating systems, of which the latest current version is OS X Mavericks, released in October 22, 2013.

It is a unix-like OS, meaning it can run most Unix and Linux software. OS X is derived from Darwin, which is derived from NeXT, which is based in part on BSD. Up through version 10.4 (Tiger), Mac OS X retained compatibility for running System 7, OS 8 and OS 9 software (Classic mode ran both Motorola 68K and PowerPC). Version 10.6 dropped support for PowerPC software (native & emulation) and runs exclusively on Intel's x86 architecture.
