The Mac OS X is a line of computer operating systems developed, marketed, and sold by Apple Inc. since 2001.
Since the launch of Mac OS X, Apple computers have been sold with Mac OS X pre-installed. Mac OS X has also been distributed on a standalone DVD, allowing customers to upgrade their Apple computers to newer versions of Apple's operating system when they are released.
Mac OS X, whether pre-installed or on a DVD, is covered by a software license agreement that states that the software is “licensed, not sold to [the user] by Apple Inc. (“Apple”) for use only under the terms of this License.” Apple's license agreements restrict the use of Mac OS X to Apple computers, and prohibit customers from installing the operating system on non-Apple computers.
