| - macOS, which stands for Macintosh Operating System, is Apple Inc.'s operating system for Apple Macintosh computers, and is closely related to iOS, Apple's operating system for other Apple products such as the iPod Touch, iPhone, and iPad. Mac OS was the first commercially successful operating system to use a purely graphical user interface. The original Macintosh team included Bill Atkinson, Jef Raskin and Andy Hertzfeld. The last version of Mac OS X was 10.9 Mavericks. With OS X 10.9, Apple removed the "Mac" prefix from the OS name. Later on, the last version to have the OS X name was OS X 10.11 "El Capitán". The lastest version is macOS 10.12 "Sierra", which returned to the original name MacOS but written in a style similar to the other flagship operating systems (tvOS, watchOS and iOS). There are a variety of views on how the Macintosh was developed and where the underlying ideas originated. While the connection between the Macintosh and the Alto project at Xerox PARC has been established in the historical record, the earlier contributions of Ivan Sutherland's Sketchpad and Doug Engelbart's On-Line System are no less significant. Apple deliberately played down the existence of the operating system in the early years of the Macintosh to help make the machine appear more user-friendly and to distance it from other systems such as CP/M and MS-DOS, which were portrayed as arcane and technically challenging. Apple wanted Macintosh to be portrayed as a system that would "just work" when you turned it on.
