Mac OS X Snow Leopard (10.6) is an operating system developed by Apple and the seventh major release of Mac OS X. 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.

Differences from Leopard[edit | edit source]

  • This version removed support for the PowerPC 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 PowerPC-only applications.
  • Finder has become completely rewritten in Cocoa to use the advantages of Mac OS X. Before that, Finder was based on the Carbon API.
  • Version 10.6.6 introduced the Mac App Store, an ESD marketplace for free and paid programs for macOS.
