Apple's upcoming Snow Leopard will give the user interface (UI) of Mac OS X a facelift, according to sources that spoke Apple Insider. The new OS is said to have a sleeker and darker UI codenamed "marble", and the site claims the latest build of QuickTime X Player provides a preview of this new interface.
These latest reports add to previous claims that similarly predicted Apple would eventually wrap Snow Leopard in a new interface rumored to go by the code-name "marble." Details were sparse, but speculation pointed to the adoption of the smoother iTunes-style scrollbars and a move towards a darker chrome motif for application windows alongside an inverted menubar with light text on a dark background.
It's possible that Apple may have already tipped its hand to this end earlier this month when it included the first external builds of its QuickTime X Player with Mac OS X 10.6 Snow Leopard build 10A286. The software included a new minimal interface consisting only of a titlebar, leaving all playback controls to reside in floating interface overlays.
Apple is expected to show off a feature complete version of Snow Leopard at WWDC 2009, which is scheduled for June 8-12.
