Apple Mac OS X 10.6 Snow Leopard Details
Mac OS X 10.6 Snow Leopard from Apple is the long-awaited successor to Apple's groundbreaking Leopard operating system. While the differences between Snow Leopard and its predecessor are not immediately evident on the surface -- the look and feel remains the same -- users will quickly realize that this version of OS X is an enhanced, streamlined, and refined edition of its predecessor. Snow Leopard is optimized for use with 64-bit processors, specifically those made by Intel. It is the first version of OS X that does not support Macs that use PowerPC G3, G4, and G5 CPUs.
