OS X, which used to be called Mac OS X, is the name of an operating system, for computers made by Apple Inc. These are called Macintosh computers, or Macs. It is different from other operating systems, because OS X is supposed to run only on Macs and not on other computers. However, people have made the OS run on computers that are not Macs. These are called Hackintosh.
The "X" in OS X, which is read aloud as "Oh Ess Ten", comes from roman numerals. OS X first came out in 2001, and is completely different than the Mac OS that it replaced. OS X is a UNIX OS that is based on NEXTSTEP, an older OS that Apple bought and turned into OS X. OS X and NEXTSTEP have a background in a kind of UNIX called BSD (more specifically FreeBSD and NetBSD). The core of OS X is an open source OS called Darwin, but Darwin cannot run OS X software.
OS X releases are named after kinds of big cats and have a version number that starts with 10. The newest version of OS X is called "Mavericks" and is version 10.9.x. The version before that is called "Mac OS X Mountain Lion¦Mountain Lion" and is version 10.8.x. There is one that will be released called "Mavericks", which is 10.9.x.

Public Beta: "Kodiak"[change | edit source]
On September 13, 2000, Apple release a $29.95 preview of Mac OS X to ask users what they think of the new operating system so far. Apple stopped the Public Beta in March 2001 because of the recent release of OS X 10.0.
Version 10.0: "Cheetah"[change | edit source]
On March 24, 2001 Apple released Mac OS X for the first time aka OS X v10.0 (codenamed Cheetah), but rather than being an excellent and successful operating system version, it was a failure due to its many computer bugs and glitches and its slow performance. Luckily this operating system version only stayed on the market up until September when it was moved up to a "higher level".
Version 10.1: "Puma"[change | edit source]
Due to many problems and complaints about Cheetah, Apple directly got to work on releasing Puma, the next big cat in Mac OS X. It was released on September 24, 2001. Apple gave 10.0 users a free Mac OS X v10.1 install CD to make up for the terrible operating system before. As of January 7, 2002, Apple said Mac OS 9 and other previous operating systems from Apple were "going in the computer scrapyard" by the end of the month (January 31, 2002) and OS X would be the default and only operating system available on all Macs.
Version 10.2: "Jaguar"[change | edit source]
Mac OS X 10.2 Jaguar was released on August 24, 2002 and was the first to have it's codename in the version branding. The Happy Mac (which formerly appeared when a Mac was starting up) was replaced with a large gray apple logo with the startup sequence of OS X 10.2 Jaguar.
Version 10.3: "Panther"[change | edit source]
Mac OS X 10.3 Panther was released on October 24, 2003 and was one of the biggest updates to OS X yet. It featured a new brushed metal interface, an updated Finder, and many more features from Jaguar the year before.
Version 10.4: "Tiger"[change | edit source]
Tiger was released on April 29, 2005 and as stated by Apple, featured more than 200 new features. Among the new features, Tiger introduced Spotlight, Dashboard, Smart Folders, updated Mail program with Smart Mailboxes, QuickTime 7, Safari 2, Automator, VoiceOver, Core Image and Core Video. Apple released the first Power Intel Macs for Tiger on January 10, 2006. Tiger ran swell on these computers. It was also the last operating system to support the Aqua color scheme.
Version 10.5: "Leopard"[change | edit source]
Mac OS X v10.5 Leopard was released on October 26, 2007. It was completely redesigned featuring a 3D Dock, a new purple color scheme, and over 200 new features. It had both support for Power PC and Intel Macs too. Leopard was the last release to have support for PowerPC.
Version 10.6: "Snow Leopard"[change | edit source]
Mac OS X Snow Leopard was released on August 28, 2009, and rather than featuring changes to the appearance, it featured "Under the hood" changes. Snow Leopard dropped support for PowerPC Macs too.
Version 10.7: "Lion"[change | edit source]
OS X Lion was first shown to the public at the "Back to The Mac" event in 2010, announced more at WWDC 2011, and released on July 20, 2011. It featured iOS like features such as a launchpad, the magic trackpad coming to MacBooks, and a new solar system color scheme. Apple also removed Rosetta making it impossible to use PowerPC apps without jailbreaking.
Version 10.8: "Mountain Lion"[change | edit source]
OS X Mountain Lion was announced on February 18, 2012, and released on July 25, 2012. It adds more features from iOS 5 and 6 to the Mac such as notifications, messaging, game center, and gaming with people on iPhones, iPods, and iPads.
Version 10.9: "Mavericks"[change | edit source]
OS X Mavericks was announced on June 10, 2013 at the 2013 Worldwide Developers Conference. It adds the Maps and iBooks applications, as well as new Finder features, better multi-display support, power improvements, and a new version of Safari. It was released on October 22 2013.

- Operating System Market Share, November 2012, courtesy of Net Applications, a marketing company which obtains its data from the Alexa Toolbar or related products. Because people who install these products on their computers are not always aware that the product reports web browsing habits back to the marketers at Alexa some security software considers the Alexa Toolbar spyware and removes it. Both the automated removal-as-spyware and the self-selecting nature of those who install software that reports on personal web browsing habits raises questions as to whether the resulting data represents a unbiased statistical sample of Internet users.
