Macintosh The Macintosh (mainly Mac since 1998) is a family of personal computers designed, manufactured, and sold by Apple Inc. (originally as Apple Computer, Inc.) since January 1984. The original Macintosh is the first successful mass-market all-in-one desktop personal computer to have featured a graphical user interface, built-in screen, and mouse. Apple sold the Macintosh alongside its popular Apple II, Apple IIGS, Apple III, and Apple Lisa families of computers until the other models were discontinued in the 1990s.
