Tried downloading it on my Mac and it wouldn't open, not sure if I was doing something wrong or if it was a bug.
Did you get any messages or pop-ups whatsoever? How far could you go?
I'll see if I can find a MacBook to test it on soon.
I got it onto my desktop and then when I hit open it just said that that application couldn't be opened. I tried it with a file unarchiver and that wouldn't work either.
