Mac OS X Version 10.6 Snow Leopard will go on sale Friday, August 28, 2009, at Apple's retail stores and Apple authorized resellers, and that Apple's online store is now accepting pre-orders. Snow Leopard features hundreds of refinements, new core technologies and out-of-the-box support for Microsoft Exchange. Snow Leopard will be available as an upgrade for Mac OS X Leopard users for $29.
Features include a more responsive Finder; Mail that loads messages up to twice as fast; Time Machine with an up to 80-percent faster initial backup; a Dock with Expose integration; QuickTime X with a redesigned player that allows users to view, record, trim and share video; and a 64-bit version of Safari 4 that is up to 50-percent faster and resistant to crashes caused by plug-ins. Snow Leopard is half the size of the previous version and frees up to 7 GB of drive space once installed.
System applications including Finder, Mail, iCal, iChat and Safari are 64-bit and Snow Leopard's support for 64-bit processors makes use of large amounts of RAM, increases performance and improves security while remaining compatible with 32-bit applications. Grand Central Dispatch (GCD) provides a new way for software developers to write applications that take advantage of multicore processors. OpenCL, a C-based open standard, allows developers to tap the power of the graphics processing unit for tasks that go beyond graphics.
