Mac OS X Leopard build 9A410

Mac OS X Leopard build 9A410 is a beta build of Mac OS X Leopard. It is the second DVD-based beta build of Leopard distributed by Apple, which was given out during NAB 2007. This build has much of the Tiger UI intact, but window decorations have been updated to the Aero-like style that would be used in the final retail version of Leopard. The intention of this build was to allow developers to test the new unified UI changes before shipping updated applications.

The default wallpaper used in this build is still the same as Mac OS X Tiger.
