Apple Unveils Mac OS X Snow Leopard

Apple has unveiled Mac OS X Snow Leopard, a refined version of its earlier operating system and the foundation for future Mac innovation. Snow Leopard builds on a decade of OS X innovation and success, new core technologies, support for Microsoft Exchange and new accessibility features. Snow Leopard will ship as an upgrade for Mac OS X Leopard users in September 2009 for $29.

“We’ve built on the success of Leopard and created an even better experience for our users from installation to shutdown,” said Bertrand Serlet, Apple’s senior vice president of Software Engineering.

To create Snow Leopard, Apple engineers refined 90 percent of the more than 1,000 projects in Mac OS X. Users will notice a more responsive Finder; Mail that loads messages 85 percent faster and conducts searches up to 90 percent faster; Time Machine with up to 50 percent faster initial backup; a Dock with Expose integration; a 64-bit version of Safari 4 that boosts the performance of the Nitro JavaScript engine by up to 50 percent and is resistant to crashes caused by plug-ins. Snow Leopard also includes an all new QuickTime X, with a re-designed player that allows users to easily view, record, trim and share video to YouTube, MobileMe or iTunes. Snow Leopard is half the size of the previous version and frees up to 6GB of drive space once installed.

For the first time, 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 to take advantage of multicore processors. GCD is integrated throughout Snow Leopard, from new system-wide APIs to high-level frameworks and programming language extensions, improving responsiveness across the system.

Snow Leopard builds support for Microsoft Exchange Server 2007 right into Mac OS X Mail, Address Book and iCal so you can use these applications to send and receive e-mail, create and respond to meeting invitations, and search and manage your contacts with global address lists. Exchange information works seamlessly within Snow Leopard so users can take advantage of OS X only features such as fast Spotlight searches and Quick Look previews.
