Much of the software in Mac OS X was extensively rewritten for this release in order to take advantage fully of modern Macintosh hardware. Addition of new end-user features was not a primary consideration: its name was intended to signify its goal to be a refinement of the previous OS X version, Leopard.
Unlike those of previous versions of Mac OS X, the goals of Snow Leopard were improved performance, greater efficiency and the reduction of its overall memory footprint. The release of Snow Leopard came nearly two years after the introduction of Mac OS X Leopard (version 10.5), the second longest time span between successive Mac OS X releases. As a result of the low price, initial sales of Snow Leopard were significantly higher than that of its predecessors. On August 28, 2009, it was released worldwide, and was made available for purchase from Apple's website and its retail stores at the price of US$29 for a single-user license. Snow Leopard was publicly unveiled on Jat the Apple Worldwide Developers Conference.
