mac app store info.plist requirements

i followed the instructions on this link: http://technology.blurst.com/unity-games-and-mac-app-store/

but i change what it suggests, and what it doesn't mention that's in the unity made info, i leave but my game won't even open after i've done what it says, done it many times still the same thing!

could someone shed some light on this?

i could post my final info.plist if it helps...

thanks!
