Hi Nat,
	As you just encountered, the Chimera 1.4 series of releases are the  
last to support OS X 10.4.  So you can't run Chimera 1.5+ without  
upgrading your OS X.  Nonetheless, the changes made to support thermal  
ellipsoids in CIF files were all in the Python layer, so you should be  
able to drop a Python file with the changes into your 1.4 distribution  
and I think it should just work.  I've attached the relevant file  
(__init__.py).  You need to put it inside your 1.4 version of  
Chimera.  Do this by right-clicking on the Chimera app in your Finder  
and choosing "Show Package Contents" from the popup menu.  This will  
bring up a new Finder window.  Navigate to Contents/Resources/share/ 
mmCIF.  Replace the __init__.py file in there with the attached  
__init__.py.  Restart Chimera and cross your fingers.
	Despite this possibly working I recommend upgrading to the 1.5  
release whenever feasible since there are some nice improvements in  
the Thermal Ellipsoids tool that you will otherwise be missing.
