Uh oh I have no idea how to test mac stuff, since it is confirmed to work on the demo at least lets start there: When you click on the "Curse of Dares" file in the "Demo Mac Build\Inner Folder.app\Contents\MacOS\Curse of dares" directory does it not open at all or is the file maybe looking blank to begin with?
Edit: Also does mac block the application in any way? Currently getting all the files reverified on Win but it gives me a warning before letting me play.
