Originally referred to as simply "Macintosh System", the underlying OS was a single-tasking disk system for the Motorola 68K CPU. Significant changes were made in MacOS 7.x.
The Macintosh originally came bundled with a Guided Tour of Macintosh, MacWrite, MacPaint, and a Tour of MacPaint and MacWrite.
