This might even be enough if you have compiled elements. I seem to understand how to set the build to PPC and i386: with my project at the front, 1. I choose Project > Edit Project Settings; 2. In the Project Info palette, I open "Build" tab; 3. In the first popup menu "Configuration", I choose "Deployment" 4. In the Setting, I edit "Architectures", and in the little window "Architectures to build for:", I check both "PowerPC" and "Intel". This gives the value of "Architectures" "ppc i386" But what is 10.4u sdk, and how can I set it to the right value? Could you please show me "step by step"? Thank you very much in advance.
