You can copy across the MixEmergency folder, which is within your Movies folder. This has all of your Presets, and a lot of MixEmergency's settings. For all of your Preferences, it gets a little more complicated... You will need to open the Terminal application, then save the preferences, copy them to your new computer, and then load them onto that new computer (also via the Terminal application). To save them to a file on the Desktop: defaults export com.inklen.MixEmergency ~/Desktop/MixEmergencyPreferences.plist To load them from the same file: defaults import com.inklen.MixEmergency ~/Desktop/MixEmergencyPreferences.plist Also, don't forget to deauthorise MixEmergency on your old computer, if you're not planning to use it anymore, as this will free up your authorisation for a new computer.
