OS X 10.8 Mountain Lion

The OS X 10.8 Mountain Lion is an operating system designed, developed, and sold by Apple from 2012 to 2013 alongside Apple’s personal computers. The system was released on July 25, 2012, available in Mac App Store for $19.99, or preinstalled on currently sold computers.

OS X has been named to signify its status as a refinement of the previous Mac OS X version, Lion, Apple’s stated aim in developing Mountain Lion was to allow users to more easily manage and synchronize content between multiple Apple devices and to make the operating system more familiar.

The OS X Mountain Lion 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 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 present in the operating system from launch. Facebook integration was also planned but unfinished at the launch date. It was released as a downloadable update later.

This software got the last update (10.8.5) on October 3, 2013, and later has been replaced by a newer version of OS X 10.9 Mavericks. Today OS X 10.8 Mountain Lion is 11 years old!
