OS X

Redirected from Mac OS X

Considered by many to be the best operating system in the world (and by me to be the best desktop operating system in the world), OS X is Apple's current flagship operating system.

See: http://www.apple.com/osx/

For a long time the official name of the OS was "Mac OS X" (pronounced "Mac OS Ten"). There were few who actually referred to it this way. Common usage was often "OS X" (either pronounced as-is or as "OS Ten").

With the release of Mountain Lion Apple finally started referring to it as "OS X" in marketing materials and the "About this Mac" dialog.
