Leopard is the codename for Mac OS X 10.5. The codename was announced at WWDC 2005, and Apple previewed the operating system at WWDC 2006 on August 7.

Leopard began shipping on October 26, 2007 at 6 PM [1] for $129 USD, after being delayed from an initial target of Spring 2007 (northern hemisphere) [2]. A full preview copy was given to attendees of WWDC 2007. It was announced at Macworld San Francisco 2008 that 5 million copies of Leopard were sold in the first 3 months after release.
