Thanks for this information. Unfortunately, while TeXShop is still  
finding the TeX binaries on my system since I installed Snow Leopard,  
the terminal is not finding commands such as texhash, updmap etc, even  
after completing all the steps below. It keeps saying "Command Not  

I'm therefore going to have to stay on TeX-Live 2007 for the time  
being. (I have a large collection of non-standard fonts so I need  
updmap etc to work. So much for my attempt at a big-bang upgrade.)  
I've tried some complex test files and they all seem to work with  
TeXShop 2.26, TeX-Live 2007 and Snow Leopard.

Kind regards,
