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 iTunes-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. Additionally, setup has been updated to a gray background instead of a blue background.

This build is also the first version of Leopard that no longer is capable of booting on PowerPC G3 processors; a PowerPC G4 or G5 is required to run this build. The default wallpaper used in this build is still the same as Mac OS X Tiger.

Bugs and quirks

 * The billboards during the copying files portion of setup doesn't work.
