2017 Air For Sale Mac G5 20Apple produced a Unix-based operating system for the Macintosh called A/UX from 1988 to 1995, which closely resembled contemporary versions of the Macintosh system software. The first versions initially had no name but came to be known as the "Macintosh System Software" in 1988, "Mac OS" in 1997 with the release of Mac OS 7.6, and retrospectively called " Classic Mac OS". Its Xserve server was discontinued in 2011 in favor of the Mac Mini and Mac Pro.Apple has developed a series of Macintosh operating systems. Its final version was macOS Catalina, as Apple went on to release macOS Big Sur in 2020. In 2001, Apple released Mac OS X, a modern Unix-based operating system which was later rebranded to simply OS X in 2012, and then macOS in 2016. Only one company, UMAX Technologies, was legally licensed to ship clones running Mac OS 8. Originally they used the Motorola 68000 series of microprocessors. (The same feat has been accomplished on ARM-based Apple silicon, but it requires an operating system built for it.) Volunteer communities have customized Intel-based macOS to run illicitly on non-Apple computers.The Macintosh family of computers has used a variety of different CPU architectures since its introduction. Intel-based Macs can run native third party operating systems such as Linux, FreeBSD, and Microsoft Windows with the aid of Boot Camp or third-party software.

The Apple Lisa project was immediately redirected to use a GUI, which at that time was well beyond the state of the art for microprocessor abilities the Xerox Alto required a custom processor that spanned several circuit boards in a case which was the size of a small refrigerator. He arranged for Apple engineers to be allowed to visit PARC to see the systems in action. In 1979 Steve Jobs learned of the advanced work on graphical user interfaces (GUI) taking place at Xerox PARC. Users interacted with the computer using a metaphorical desktop that included icons of real life items, instead of abstract textual commands.In 1978 Apple began to organize the Apple Lisa project, aiming to build a next-generation machine similar to an advanced Apple II or the yet-to-be-introduced IBM PC. The rest of the original Mac team would include Bill Atkinson, Bob Belleville, Steve Capps, George Crow, Donn Denman, Chris Espinosa, Andy Hertzfeld, Bruce Horn, Susan Kare, Larry Kenyon, and Caroline Rose with Steve Jobs leading the project. His initial team would eventually consist of himself, Howard, Joanna Hoffman, Burrell Smith, and Bud Tribble. Raskin was authorized to start hiring for the project in September 1979, and he immediately asked his long-time colleague, Brian Howard, to join him. Instead of a GUI, it intended to use a text-based user interface that allowed several programs to be running and easily switched between, and special command keys on the keyboard that accessed standardized commands in the programs. The design at that time was for a low-cost, easy-to-use machine for the average consumer. At the same time that the Lisa was becoming a GUI machine in 1979, Jef Raskin began the Macintosh project. Bud Tribble, a member of the Mac team, was interested in running the Apple Lisa's graphical programs on the Macintosh and asked Smith whether he could incorporate Lisa's 68000 microprocessor into the Mac while still keeping the production cost down. Smith's first Macintosh board was built to Raskin's design specifications: it had 64 kilobytes (kB) of random-access memory (RAM), used the 8-bit Motorola 6809E microprocessor, and could support a 256×256- pixel black and white raster graphics (bitmap) display. He attributed the eventual success of the Macintosh to people like John Sculley "who worked to build a Macintosh market when the Apple II went away". In that same interview, Wozniak said that the original Macintosh "failed" under Jobs and that it was not until Jobs left that it became a success.
