OS X (pronounced OS ten; "X" is a Roman numeral), version 10.6, codenamed Snow Leopard, is the 7th major release of Apple's Mac operating system. It was released on August 28th, 2009. It is a Unix-based graphical interface operating system.
Snow Leopard is the only OS X released in both 32 and 64 bit versions (prior versions were only 32 bit and subsequent ones only 64 bit). Snow Leopard works with Intel-based Macs. It is the last version to support Rosetta (software that allowed many PowerPC applications, from the prior platform, to run on Intel-based Macs without modification), although it was not installed by default in Snow Leopard.
