, 1984 by Apple Inc.. The most fascinating feature of Mac was it its GUI ( Graphical user interface ). The Macintosh system software was actually based on the Lisa OS, which the Apple used to design for the Lisa computer in 1983 and, as part of an agreement , it also used concepts from the Xerox PARC Xerox Alto, which Steve Jobs and several other Macintosh team members had previewed.
Dear readers, it was all about the importance of advertisement that after it was created, the company bought all 39 pages of Newsweek magazine of 1984 November/December edition.

The first version of Mac OS X was launched in 1999. The later releases were named after big cats.

Macintosh provides so many inbuilt mac utilities which can handle almost all the odds of Mac OS. Recently when I had problem with my Mac speed I used a third party mac optimization tool named Stellar Speed Up Mac. Its a mac utility to delete unused data , and also to uninstall applications which are none of any use. In this it creates some free space on Mac hard drive and ultimately enhance Mac speed.
