>The question is what was the last version of Fox that could be used to write programs for the mac?

While the others answered your question, what they didn't say was the VFP 3.0/Mac was awful. It was slow and buggy. None of the people I knew who do serious VFP and serious Mac stuff have any interest in using it.

>Are there any other suggestions on writing an app for a client that only uses macs?

I've heard that there's a Windows emulator you can run on a Mac that lets you run VFP apps.
