After I download the link, I cannot open the download. I am on a Mac. If I download the OS version, i receive the message, " “cultris.exe.app” is damaged and can’t be opened. You should move it to the Trash." If I try to download the windows version on my Mac, I have nothing to open it with. It is not a problem about allowing it to be opened, I know how to do that. Really want to play this.
try running this command in terminal before downloading and running the mac app. sudo spctl --master-disable
you should also check your system preferences to make sure you allow apps downloaded from anywhere to be opened and not just the app store.
lastly another a user (DEF) made a modified mac app that runs a little smoother. you can check that out here: http://gewaltig.net/Forums/Thread.aspx?pageid=1&t=996~1
alternatively wine is a program you can download for mac that will allow you to run the windows version (though in my opinion it has a little lag)
