Mac OS X Developer Preview 3

Mac OS X Developer Preview 3 is the third Developer Preview of Mac OS X Public Beta. This build is the first build of Mac OS X to contain the Aqua theme, replacing the Platinum theme used in Mac OS 9 and before. Likewise, the rainbow Apple logo has been changed to a sleek blue color. The logo has no effect when you click it. A prototype version of the Dock is also included. This build was demonstrated at the Mac OS X introduction in 2000-01
