Yeah I think starting with OSX 10.7 I guess they implemented a mechanism called "Gatekeeper" which is kind of oriented towards only running things from the App store eventually I guess...

And they want people to purchase a special certificate and then "digitally sign" the application, which I haven't done yet.

Unless the default settings have changed from 10.8 you don't actually need to switch your system security settings, you can just right-click on the app and pick "Open" from the menu that pops up and that will automatically make an exception for that one particular app.

So if you run into this with future Moi versions, just right-click and pick "Open", you only need to do that one time for an app for that app to be allowed to run.
