Mac OS
Mac OS is a series of graphical user interface–based operating systems developed by Apple Inc. for their Macintosh line of computer systems.
Description
The original operating system was first introduced in 1984 as being integral to the original Macintosh, and referred to as the "System".
Referred to by its major revision starting with "System 6" and "System 7", Apple rebranded version 7.6 as "Mac OS" as part of their Macintosh clone program in 1996. The Macintosh, specifically its system software, is credited with having popularized the early graphical user interface concept.
There are two architectural legacies of Mac OS.
Up to major revision 9, from 1984 to 2000, it is historically known as Classic Mac OS.
Major revision 10, from 2001 to present, was originally branded "Mac OS X", renamed to "OS X" in 2012, and announced to be renamed to "macOS" in the upcoming version in 2016.
Both legacies share a general interface design, and there has been some overlap of application frameworks for compatibility; but the two systems have different origins and use deeply different architectures.
