(3) (A/UX) (Apple/UniX) A version of Unix for earlier Macintosh 68000-based computers from Apple. Introduced in 1988 and based on AT&T's Unix System V, A/UX included the Mac's Finder graphical interface; however, one of its main advantages was the Unix command line, which offered a host of functions for manipulating text and data. Not widely used, when Apple switched from Motorola 68000 to PowerPC chips in 1994, A/UX was not ported to the new hardware, and its last version was released a year later. Unix After All Starting in 1999, Apple switched to Mac OS X, a Unix-based operating system, and the Mac became a Unix machine after all. See Mac OS X and Unix.
