Mac OS X version 10.6 “Snow Leopard” is the seventh major release of Mac OS X, Apple’s desktop and server operating system. The upgrade to Mac OS X focuses on improving performance, efficiency and reducing its overall memory footprint compared to its predecessor Mac OS X v10.5 “Leopard”, rather than new end-user features. This is also the first Mac OS release dating back to System 7.1.2 that does not support the PowerPC architecture, as Apple now intends to focus on its current line of Intel-based products.
Refined, not reinvented
Mac OS X is renowned for its simplicity, its reliability, and its ease of use. So when it came to designing Snow Leopard, Apple engineers had a single goal: to make a great thing even better. They searched for areas to refine, further simplify, and speed up — from little things like ejecting external drives to big things like installing the OS. In many cases, they elevated great to amazing. Here are just a few examples of how your Mac experience was fine-tuned.
A more advanced, more nimble Finder
The Finder has been completely rewritten in Cocoa to take advantage of all the modern technologies in Mac OS X, including 64-bit support and Grand Central Dispatch. It’s more responsive from top to bottom, with snappier performance throughout the Finder. And it includes new features such as customizable Spotlight search options and an enhanced icon view that lets you thumb through a multipage document or watch a QuickTime movie.
