Apple's '''macOS''' is a [[UNIX]]-based operating system designed by [[Apple]] solely and exclusively for use on [[Macintosh]] computers.

The latest version is macOS 11.0, named ''Big Sur''. Previous versions were known as '''macOS 10''' (until 2020), '''OS X''' (until 2016) and before that '''Mac OS X''' (until 2012).
These are derivatives of [[NeXT]]'s OPENSTEP operating system, rebuilt to resemble the classic Macintosh operating system.

The operating system on Macintosh computers before Mac OS X was known as "Mac OS 9", being the ninth major version of the original Mac OS. It was known as "System 1" (1984) through "System 7.5.5" (1996), until rebranded "Mac OS" during 1996 with "Mac OS 7.6" released the next year.

==Keyboards==
===Using PC keyboards===
When a PC keyboard is connected to a Macintosh via USB, the [[Windows key]]s act as the [[Command key]]s and the [[Alt key]]s act as the [[Option key]]s.
The positions of these keys are reversed from the Macintosh standard, with PCs having the [[Alt key]]s innermost.

Within System Preferences, under ''Keyboard'' or ''Keyboard & Mouse'' (depending on system version), you can remap the modifier keys, and thereby swap Option and Command.
