Mac OS X Leopard build 9A466

The last DVD-based beta build of Mac OS X Leopard distributed at WWDC '07. This build marked the second revision of the updated iTunes-like Aqua interface that was kept until Snow Leopard. Most of the Tiger assets have been removed, although some icons are still from Tiger, as well as certain UI buttons (such as the window controls).

The menu bar and dropdowns in this revision utilized a flat design that is different from both Tiger, and the retail version of Leopard. This menu bar design would not be used again until Mac OS X Yosemite.

This build also introduced the 3D dock that would be used from Leopard until Mavericks.

The default theme and wallpaper used is "Grass Blades" which would be ultimately replaced by "Aurora" in the retail version of Leopard. This build's setup theme is the same as Tiger, only changing the name to Mac OS X Leopard Developer Preview.
