Ubuntu是一个以桌面应用为主的GNU/Linux操作系统，基于Debian发行版和GNOME桌面环境，与Debian的不同在于它每6个月会发布一个新版本。

普通的桌面应用版可以获得18个月的支持，标为LTS的桌面应用版可以获得更长时间的支持。其桌面应用系列可以获得为期三年的技术支持，服务器版可以获得为期五年的技术支持。Ubuntu的目标在于为一般用户提供一个最新的、同时又相当稳定的主要由自由软件构建而成的操作系统。Ubuntu具有庞大的社区力量，用户可以方便地从社区获得帮助。

这一代最大的特色是全面导入名为Unity的新界面，这也是先前使用在Netbook Remix版本上的界面，相较过去的界面号称更为美观且简单易用。而Ubunty也会针对使用者的显示适配器进行判断，若是安装者的显示适配器性能不足，也会自动改为传统界面，当然看不惯Unity界面，也可以手动选择传统界面。

It is the operating system that powers many of the company’s mobile devices, including the iPhone and iPod Touch; the term also included the versions running on iPads until the name iPadOS was introduced with version 13 in 2019. It is the world’s second-most widely installed mobile operating system, after Android. It is the basis for three other operating systems made by Apple: iPadOS, tvOS, and watchOS. It is proprietary software, although some parts of it are open source under the Apple Public Source License and other licenses.

Unveiled in 2007 for the first-generation iPhone, iOS has since been extended to support other Apple devices such as the iPod Touch (September 2007) and the iPad (introduced: January 2010; availability: April 2010.) As of March 2018, Apple’s App Store contains more than 2.1 million iOS applications, 1 million of which are native for iPads. These mobile apps have collectively been downloaded more than 130 billion times.

Major versions of iOS are released annually. The current stable version, iOS 15, was released to the public on September 20, 2021

OS X Mountain Lion (version 10.8) is the ninth major release of macOS, 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, rather than every two years or so. 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. Mountain Lion was the last paid upgrade for an OS X major release, with OS X Mavericks and later being free. Apple later allowed free downloads of the OS, starting on June 30, 2021.

It brought many developments made in Apple’s iOS, such as an easily navigable display of installed applications, to the Mac, and includes support for the Mac App Store, as introduced in Mac OS X 10.6 Snow Leopard version 10.6.6. On February 24, 2011, the first developer’s preview of Lion (11A390) was released to subscribers to the Apple Developer program. Other developer previews were subsequently released, with Lion Preview 4 (11A480b) being released at WWDC 2011.

Lion was released to manufacturing on July 1, 2011, followed by its final release via the Mac App Store on July 20, 2011. Apple reported over one million Lion sales on the first day of its release. As of October 2011, Mac OS X Lion had sold over six million copies worldwide.

Lion is the final release whose development was overseen by Bertrand Serlet, considered the “founding father of Mac OS X”.

Although originally paid, Apple later allowed free downloads of the OS, starting on June 30, 2021.
