Starting with the original Mac OS and moving through to the modern macOS, this section will cover the major milestones:

Early Mac OS (1984-1996)

The story of Mac OS begins with the release of the Macintosh in 1984. The early versions were simple yet revolutionary, introducing the world to the graphical user interface:

This period was marked by the establishment of the graphical interface that would become a hallmark of Mac systems.

Mac OS X and the Introduction of XNU (1999-2009)

The release of Mac OS X in 1999 marked a significant change for Apple, introducing a new architecture that combined elements of BSD Unix with the old Mac OS interface:
