Well, I *hate* to give up, but...
One last thing you could do is to e-mail the developers using the form at the bottom of Amanita's 'About' page and ask them for help. Let them know you're using a Mac, and provide a link to this thread. And please post back if you find out anything. =)
Edit: Just to note that the contact form is now here:
