Mac OS X 10.6 'Snow Leopard' makes a video appearance

Screenshots and user-uploaded videos of OS X 10.6 (aka Snow Leopard) have been popping up as the first quarter of 2009 inches ever closer.

During WWDC last June, Apple's Jordan Hubbard gave a presentation which included a slide saying that Snow Leopard was slated for a Q1 2009 release. The OS update is comprised mainly of un-flashy improvements that are geared toward increased performance and optimization of the new hardware architecture of the latest Macs.

German blog Sevenmac.de received videos and screenshots of 10.6, which include the developer preview of Safari 4 in use, and the Exchange-compatible address book. Again, there's nothing dramatically different about Snow Leopard on the surface, other than the activity monitor showing a handful of 64-bit plug-ins running.

Snow Leopard is expected to appear at Macworld 2009.
