I've downloaded Final Vinyl, but Mountain Lion says it can't be opened!
Mountain Lion includes a security feature called Gatekeeper, which prevents certain applications downloaded from the internet from being installed or opened. To bypass Gatekeeper so that you can use Final Vinyl, find Final Vinyl in your Applications folder, then hold the Control key and click on the Final Vinyl icon. Select "Open" from the menu that appears. You'll get a message from Mountain Lion asking you to verify that you want to open Final Vinyl. Choose "Open". You may have to enter your password at this point. Final Vinyl will now open normally.
You'll only have to complete this process once. This will add Final Vinyl to Gatekeeper's exceptions list, and you can now open Final Vinyl just like any other application.
