Mac OS X (pronounced /mæk oʊ ɛs tɛn/)[1] is a line of graphical operating systems developed, marketed, and sold by Apple Inc., the latest of which is pre-loaded on all currently shipping Macintosh computers. Mac OS X is the successor to the original Mac OS, which had been Apple's primary operating system since 1984. Unlike its predecessors, Mac OS X is a Unix-based operating system[2] built on technology that had been developed at NeXT through the second half of the 1980s until Apple purchased the company in early 1997.
The first version released was Mac OS X Server 1.0 in 1999, and a desktop-oriented version, Mac OS X v10.0 followed in March 2001. Since then, five more distinct "end-user" and "server" versions have been released, most recently Mac OS X v10.5 in October 2007. Releases of Mac OS X are named after big cats, for example Mac OS X v10.5 is usually referred to by Apple and users as "Leopard".
The server edition, Mac OS X Server, is architecturally very similar to its desktop counterpart but includes workgroup management and administration software tools that provide simplified access to common network services, including a mail transfer agent, a Samba server, an LDAP server, a domain name server, and others. It is included with Apple's Xserve server hardware, but is designed to run on most of Apple's computer models.
Apple also produces specialized versions of OS X for use on three of its consumer devices, the Apple TV,[3] the iPhone and the iPod touch
