Hi Koen,

Going universal is easy (at least in theory). In the project info,  
you have to make sure you link against the 10.4 Universal SDK.
Then make sure to select both Intel and PPC in the build settings,  
and that's it. At least, when the code itself is "universal". All  
Cocoa code is universal by default. Plain C code might cause some  
trouble (endian issues, ...), but as far as BC is concerned, this  
will only be a small percentage, I guess.

I'm not entirely sure that the Universal binary will still work as  
expected on pre-Tiger systems. Therefore, you'll have to do a little  
more work. Hint #2 in the following article gives a good overview on  
how to support pre-Tiger systems with universal binaries: http:// 

best wishes,
