We are stuck with the black boxes on the Mac for awhile, unfortunately. (I am not happy about it either as I am primarily a Mac user). It is related to the differences between DirectX which the Windows version uses for Alice graphics, and OpenGL, which the Mac and linux version uses (as they cannot use DirectX).

The two packages handle the alpha channel for graphics (related to transparency), and we have yet to figure out what we have to do on the Mac side to compensate.

This will not be an issue in Alice 3, as we are using OpenGL for both the Windows and Mac versions.
