This is at least a partial fix -- you still get annoying error
messages, but the animation will work.  Assuming you have installed
Mathematica.app in the /LocalApps directory, look at the file
/LocalApps/Mathematica.app/Kernel/NeXT/StartUp/PSDirect.m, locate
the line that says

	$RasterFunction = Identity
	
and change it to read

	$RasterFunction = $DisplayFunction
	
and re-launch Mathematica.
