I have a small plist my app uses for reference, to contain some OS-related constants that there is a remote possibility could change at some point in the future. Because it should probably not ever be touched, I tucked it away in the MacOS subfolder so that anyone trying to localize files will probably not notice its existence and not mess with it. My question is, in this Code Signing environment, what is checked by the system for consistency? If that file were altered out of necessity, would it break the app?
