Apple’s .Mac Web site has been updated in advance of the keynote unveiling today with a screenshot and logo of Mac OS X 10.3 “Panther.” The screenshot shows what is apparently a new Finder window in Apple’s Brushed Metal appearance like Apple’s iApps such as iTunes, iMovie and iChat. The “X” logo for the new operating system is also a bit different with this update. The details were listed on a preview page for a new version of iDisk — information on the new online storage tool can be found here.
