Mac OS X Snow Leopard (version 10.6) is the seventh and current major release of Mac OS X, Apple's desktop and server certified Unix operating system.[2]This version of Mac OS X focuses on improving performance, efficiency and reducing its overall memory footprint compared with its predecessor Mac OS X v10.5 "Leopard", rather than new end-user features. This is also the first Mac OS release since the introduction of System 7.1.2 that does not support the PowerPC architecture, as Apple now intends to focus on its current line of Intel-based products.[3]
Snow Leopard was released on August 28, 2009,[4] and is available as an upgrade for Intel-based Macintosh computers. Single-user licenses and "family pack" licenses for up to five computers are available. For qualifying Mac computers bought after June 8, 2009 Apple offered a discounted price through their "up to date" program provided your order was faxed or postmarked by December 26, 2009. While the license for the standalone retail version of Snow Leopard restricts that upgrade to users of Mac OS X v10.5 "Leopard", the company has acknowledged that there is no technical barrier preventing a direct upgrade from Mac OS X v10.4 "Tiger".[5] The recommended upgrade path from Apple for OS X "Tiger" is through the current release of the "Mac Box Set", which includes Mac OS X Snow Leopard, iLife '09, and iWork '09.
