Mac OS X Mountain Lion : ウィキペディア英語版
OS X Mountain Lion

OS X Mountain Lion (version 10.8) is the ninth major release of OS X (formerly Mac OS X), Apple Inc.'s desktop and server operating system for Macintosh computers. OS X Mountain Lion was released on July 25, 2012 for purchase and download through Apple's Mac App Store, as part of a switch to releasing OS X versions online and every year. Named to signify its status as a refinement of the previous OS X version, Lion, Apple's stated aims in developing Mountain Lion were to allow users to more easily manage and synchronise content between multiple Apple devices and to make the operating system more familiar.
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 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 launch date. It was released as a downloadable update later.
OS X Mountain Lion received positive reviews, with critics praising Notification Center, Messages, and speed improvements over Mac OS X Lion, while criticizing iCloud for unreliability and Game Center for lack of games. Mountain Lion sold three million units in the first four days, and has sold 28 million units as of June 10, 2013, making it Apple's most popular OS X release.
==History==

OS X Mountain Lion was officially announced by Apple on their website on February 16, 2012, as a successor to Mac OS X 10.7 Lion. It achieved golden master status on July 9, 2012.〔(【引用サイトリンク】url=http://9to5mac.com/2012/07/09/apple-pushes-mountain-lion-gm/ )〕 Following a soft transition started with Mac OS X Lion, Apple consistently refers to OS X Mountain Lion as "OS X" rather than "Mac OS X".〔
During the Apple Worldwide Developers Conference keynote on June 11, 2012, Apple announced a "near final" release version of Mountain Lion for developers, with the public version arriving in July 2012 at a price tag of US$19.99 (€15.99 in Europe, £13.99 in the UK, $20.99 in Australia and ¥128 in Mainland China). The third generation MacBook Pro, revised MacBook Air, iPad Smart Case, and third-generation AirPort Express were announced at the keynote as well.
The specific release date of July 25 was not confirmed until the day before, July 24, by Apple CEO, Tim Cook, as part of Apple's 2012 third-quarter earnings announcement. It was released to the Mac App Store on July 25, 2012, where it sold 3 million units in the first four days of release.〔
An update for Mountain Lion, version 10.8.1, was released on August 23, 2012. It resolved issues with iMessages, Migration Assistant, Safari, Microsoft Exchange Server, Mail, and many other applications. Tests of the update revealed that 10.8.1 also improved battery life on laptops, albeit gaining back only half of the battery life that was lost in updating to Mountain Lion. Although 10.8.1 improved battery life for some customers, others continue to complain about reduced battery life and a constant drop in battery health, ultimately resulting in a "Service Battery" message.
