You're the second to ask this, but my mac is in the shop so I can't check on anything.
I moved this into the Mandelbulber forum instead of the Mandelbulb 3D forum, where hopefully the right people will see it and reply.
Good luck with it
EDIT - Now that I checked, it was you asking earlier, but in your introduction topic!
Now that the question is in the right forum, it should be answered as soon as anyone who knows what to do sees it. Could be quickly, or not - I have no idea if this is a common problem or not. Once again, Good Luck with it.
