HOTiSO has released “Mac OSX Mountain Lion”. It is the ninth major release of OS X (formerly Mac OS X), Apple Inc.’s desktop and server operating system for Macintosh computers. Built on a rock-solid UNIX foundation, OS X is engineered to take full advantage of the technologies in every new Mac. And to deliver the most intuitive and integrated computer experience. The operating system gained the new malware-blocking system Gatekeeper and integration with Apple’s online Game Center and iCloud services, while the Safari web browser was updated to version 6. As on iOS, Notes and Reminders became full applications, separate from Mail and Calendar, while the OS X iChat application was replaced with a version of iOS’s Messages. Mountain Lion also added a version of iOS’s Notification Center, which groups updates from different applications in one place. Integrated links allowing the user to rapidly transfer content to Twitter were added to the operating system from launch. Facebook integration was also planned but unfinished at launch date,[3] and released as a downloadable update later.
