I have this issue as well. After taking the plunge and downloaded it when I run it, I get a: "A stack cannot be sound" error. Certainly don't want to be pushy, but I hope that Chipp Walters can find the bandwidth to make it so it works once again on the Mac, as it seems form watching some people on YouTube who have tweaked their UI, it can really polish the UI look and feel.

I realize that it is being greedy since this is a free app Chipp created, and he may not have the bandwidth (or whatever0 to deal with it currently. But it is a shame that we Mac users are left out int eh lurch for now.
