A/UX is a Unix-based operating system from Apple Computer for Macintosh computers, integrated with System 7's graphical interface and application compatibility. It is Apple's first official Unix-based operating system, launched in 1988 and discontinued in 1995 with version 3.1.1.[2] A/UX requires select 68k-based Macintosh models with an FPU and a paged memory management unit (PMMU), including the Macintosh II, SE/30, Quadra, and Centris series.[3]
Its foundation is UNIX System V Release 2.2, with features from Releases 3 and 4[citation needed] and from BSD versions 4.2 and 4.3. It is compliant with POSIX and System V Interface Definition (SVID), and includes TCP/IP networking since version 2. Having a Unix-compatible, POSIX-compliant operating system enabled Apple to bid for large contracts to supply computers to the U.S. federal government.[4][5]
A/UX was described by MacUser as "the most interesting and impressive software to have come out of Apple since HyperCard" and by InfoWorld as "an open systems solution with the Macintosh at its heart".[6]
