I haven't experienced such problems with any of those versions on Mac,  
and neither using OpenCSG-1.2.0.
Empty screen problems are the least fun to debug, but let's see what  
we can do..

To make sure all is well, please grab the latest build (2009-12-31),  
open a Terminal and send med the output of this:
$ otool -L OpenSCAD.app/Contents/MacOS/OpenSCAD

Then, start OpenSCAD on the cmd-line:
$ ./OpenSCAD.app/Contents/MacOS/OpenSCAD

Now, what exactly doesn't work?
o Do you get the same behavior with all view methods (F9-F12) ?
o Does it make a difference whether you use "Compile" (F5) or "Compile  
and Render (CGAL)" (F6) ?
o Are there any meaningful output anywhere which could give me a hint?  
I know there isn't much debug output going on atm..

Also, the output of 'glewinfo' could be useful, just in case.
