I've seen some forum posts regarding failed exports of processing applications from Mac. I'm having the same issue and wondered if it had been resolved?
Before anyone asks I've updated the libJMyron.jnlib (that's not the issue).
So what happens is, my application launches but never loads anything. I did some digging around in the code and it looks as though the 'libJmyron' is failing at 'StartCamera()'.
Then it says that there's no 'Quicktime camera found'. I can see this partially by opening the 'libJMyron.jnilib' in nano.
