About the error in Mac OS X you can solve this by opening the System Preferences/Security and Privacy and click on the "lock icon" on the left bottom side of the window so you can access the "Allow apps downloaded from:" options and you need to choose "Anywhere", so you allow any application to open and not only the application from the App Store.
