Logging into an A/UX system
Type: Multitasking, multiuser
Creator: Apple/UniSoft
Architecture: Macintosh
Current Version: 3.11
Date Released: 1988

After Steve Jobs left Apple, they scrambled to put together a system that could compete with NeXT. Hearing that NeXT was going to enter the Unix workstation market, Apple commissioned UniSoft to help port SYSVr2 to its Macintosh II lineup.

Significant Versions


This version is more infamous because it included the source code


A/UX 1.1.1's GUI

This is a super barebones version, the toolbox is barely able to run the terminal application and some simple desktop widgets.


A/UX 2.0's GUI

Version 2.0 is more polished, and able to run a finder that is more parallel to System 6.


A/UX 3.0's GUI

This is the best version to get ahold of. 3.0 emulates a System 7.0.1 environment.

How do I get this to run?!

You will need an actual Macintosh that is supported. The best machines are the Quadra series. Note, not all Quadras will run A/UX. More information can be found on aux-penelope. Optionally the Shoebill emulator can run A/UX 1.1.1, 2.0 & 3.0.0 (*NOTE that this doesn't include 3.0.1 or 3.1).

What Runs?

Some early GNU stuff will compile, however keep in mind that during the lifespan of A/UX GNU started up the Apple protest over the 'look and feel' lawsuit.
