Mac OS
The first operating system for the Mac, System 1.0, released in 1984, was only 216K in size, and started the personal computer revolution. It was a breakthrough in interface design - simple and easy to use with click-and-drag methods for moving objects and pull-down menus and icons. There were a few problems, however, with this early operating system. Copying disks took a long time due to limited memory and the user was not able to create empty folders.

Legend has it that Apple co-founder Steve Jobs visited the Xerox PARC complex, saw the work the team was doing on their Graphical User Interface and promptly used the ideas to develop the Macintosh operating system, which in turn inspired Microsoft’s Windows operating system. While both Jobs and Gates made a visit to Xerox, it is true is that Jobs hired some of the people from Xerox to help with the Macintosh GUI, the development of which predated Jobs’ visit to PARC.

There have been various updates to the Mac operating system over the years - the latest is OS X.
