Mac OS X version 10.5 “Leopard” is the sixth major release of the Mac OS X operating system for Apple’s Mac line of personal computers, the successor to Mac OS X v10.4 "Tiger". Leopard was shown to developers for the first time at the 2006 Worldwide Developers Conference (WWDC).[2] Leopard was released on October 26, 2007, and is being sold for US$129, GB£85, AU$158[3] and NZ$199[4]. Apple also sells a US$199 "Family Pack" that includes five licenses, and the single user version for students at US$116 (both prices plus tax).[5] Apple offers a US$9.95 (plus tax)[6] upgrade to people that purchase new Apple computers between October 1, 2007 and December 29, 2007 that do not already have Mac OS X v10.5 pre-installed or a Leopard upgrade DVD included starting October 26, 2007.[7]
According to Apple, Leopard contains over 300 changes and enhancements,[8] covering core operating system components as well as included applications and developer tools. Leopard introduces a significantly revised desktop, with a redesigned Dock, Stacks, a semitransparent menu bar, and an updated Finder that incorporates the Cover Flow visual navigation interface first seen in iTunes. Other notable features include support for writing 64-bit graphical user interface applications, an automated backup utility called Time Machine, support for Spotlight searches across multiple machines, and the inclusion of Front Row and Photo Booth, which were previously only included with some Mac models.
