Apple Mac OS X Snow Leopard builds on a decade of OS X innovation and success with hundreds of refinements, new core technologies and out of the box support for Microsoft Exchange.
To create Snow Leopard, Apple engineers refined 90 percent of the more than 1,000 projects that make up Mac OS X. Users will notice refinements including 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 easily 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 7GB of drive space once installed. For the first time, system applications including Finder, Mail, iCal, iChat and Safari are 64-bit and Snow Leopards 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 revolutionary 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 incredible power of the graphics processing unit for tasks that go beyond graphics.
