You *can* use X11 with OS X, but Mathematica does not. It has a custom 
front end for the Mac.

The implementation of display postscript used in current versions of 
Mathematica (going back to version 1) does not rotate text on the 
screen properly. I believe that this is due to the underlying QuickDraw 
routines that the display postscript calls. Printing works fine.

As far as I know, this is supposed to be fixed in a future version. 
Since QuickDraw has been deprecated, I hope that the Front End for 
Mathematica will soon use Quartz. They may have talked about this at 
the recent Mathematica conference, but I could not attend.
