Since the news released few months ago, Apple have now officially announced Mac OS X 10.6 as an upgrade version of exisiting “Snow Leopard” at their WWDC 2009 keynote on 8th June 2009.
A $29 upgrade for existing Leopard users, Snow Leopard – under collaboration with Intel Corp., will only run on Intel-based Macs – brings out faster performance, with Microsoft Exchange 2007 support, QuickTime X and OpenCL support.

Been through a full rewrite in Cocoa, makes Snow Leopard even faster than before – according to Apple source say 90-percent of the OS has been refined. Icon previews, animations will be faster and improved, even more the trash emptying will be quicker than before.
You could present the active windows of any one application simply by clicking and holding its icon in the Dock. Not to mention many other major improvements and enhancements made within the OS.
Snow Leopard also brings support for multi-core systems and true 64-bit, with a new “Grand Central Dispatch” for dealing with multi-threading and new system-wide APIs and an object-oriented framework.
Apple demonstrated this with Mail, which under Snow Leopard uses fewer threads when idle and improves responsiveness. All of Apple’s core apps are now fully 64-bit. Graphics, too, have been addressed, with OpenCL: that delivers hardware abstraction, c-based language, automatic optimization and numerical accuracy, and is an open standard that all the major GPU companies have signed up to.
Safari 4
On the browsing side, Amazing Safari 4 web browser is now claiming to be ‘Crash Resistance’ in any platform, though it won’t be a sole exclusivity of Snow Leopard.

Safari 4 will automatically refreshes a page should it crash, rather than send down the whole browser and is indeed rather like Chrome though Apple claims Safari 4 will be even faster than Google’s speed machine. You could download the Safari 4 here.
Launching in September, Snow Leopard will be priced at $29 for an individual upgrade for a Leopard user, or $49 for a family pack.
