Mac OS X Snow Leopard

Mac OS X Snow Leopard (10.6) is an operating system developed by Apple and the seventh major release of Mac OS X. This version removed support for the PPC architecture due to Apple's intent to support Intel processors. It is also the last version to use Rosetta, and thus the last version to run PPC-only applications. Version 10.6.6 introduced the Mac App Store. Snow Leopard is one of Apple's longest lasting Mac OS X operating systems with five years of support and launched with largely positive reviews.
