Howdy,

I agree that it would be desirable behavior; and you say that is the  
behavior on your iBook! I'd find out what versions of the graphicx  
and epstopdf (which really only sets a processing step for .eps files  
for graphic(s/x)) packages you are using on those systems. TeXShop is  
only playing a passive role in this processing.

By the way, if you simply drop the changed .eps file onto TeXShop it  
will automatically process it into a pdf. Then using the  
extensionless \includegraphics{} calls won't process the .eps files  
again and it will be up to date.

Good Luck,

Herb Schulz
