Yesterday at the WWDC Apple has offered more details about its newest operating system, Mac OS X 10.6 Snow Leopard, which is scheduled to debut in September, about one month before Microsoft ships Windows 7. The Snow Leopard has full-on 64-bit support, with more of its core apps being 64-bit, is faster and more secure, is ready to take full advantage of multi-core processors, comes with OpenCL and QuickTime 10, and is said to require half the storage space of its predecessor when installed.

"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. "Apple engineers have made hundreds of improvements so with Snow Leopard your system is going to feel faster, more responsive and even more reliable than before."

According to Apple, those running Mac OS X 10.5 will be able to get the Snow Leopard upgrade for just $29, while a Mac Box Set including Mac OS X Snow Leopard, iLife '09 and iWork '09 and will be available at $169.
