Classic Mac OS is the original operating system developed by Apple Inc. for Macintosh computers, starting from its introduction in 1984 until it was succeeded by macOS (formerly known as Mac OS X) in 2001. The Classic Mac OS is notable for its graphical user interface (GUI), which was one of the first to be widely adopted, allowing users to interact with their computers using a mouse and visual icons rather than text-based commands.
