Apple's effort to expand upon and develop a replacement for its classic Mac OS in the 1990s led to a few cancelled projects, code named Star Trek, Taligent, and Copland.Īlthough the classic Mac OS and macOS (Mac OS X) have different architectures, they share a common set of GUI principles, including a menu bar across the top of the screen the Finder shell, featuring a desktop metaphor that represents files and applications using icons and relates concepts like directories and file deletion to real-world objects like folders and a trash can and overlapping windows for multitasking.īefore the arrival of the Macintosh in 1984, Apple's history of operating systems began with its Apple II series computers in 1977, which ran Apple DOS, ProDOS, and later GS/OS the Apple III in 1980, which ran Apple SOS and the Apple Lisa in 1983, which ran Lisa OS and later MacWorks XL, a Macintosh emulator.

Prior to the introduction of Mac OS X, Apple experimented with several other concepts, releasing different products designed to bring the Macintosh interface or applications to Unix-like systems or vice versa, A/UX, MAE, and MkLinux.

It is the basis of Apple's current system software for its other devices – iOS, iPadOS, watchOS, and tvOS. The current macOS is pre-installed with every Mac and receives a major update annually. It brought an entirely new architecture based on NeXTSTEP, a Unix system, that eliminated many of the technical challenges that the classic Mac OS faced, such as problems with memory management. It was developed between 19 after Apple's purchase of NeXT. The current Mac operating system is macOS, originally named 'Mac OS X' until 2012 and then 'OS X' until 2016. It was noted for its ease of use, and also criticized for its lack of modern technologies compared to its competitors. The system, rebranded 'Mac OS' in 1997, was pre-installed on every Macintosh until 2002 and offered on Macintosh clones for a short time in the 1990s. In 1984, Apple debuted the operating system that is now known as the 'Classic' Mac OS with its release of the original Macintosh System Software.

Two major families of Mac operating systems were developed by Apple Inc. For a list of all Apple operating systems, see List of Apple operating systems.
