I'm running DrivePulse in the background of my Mac Pro. Every few days it returns a warning (harmless as it may be) for two preference files. The files are: "/Users/name/Library/Preferences/com.TegraUSA.Tailpiece.plist" and "/Users/name/Library/Preferences/com.roverbetter.couvade.plist" It reports that these pref files are corrupt. I drag them to the trash, yet whatever app is creating them recreates them and the cycle begins all over. I highly doubt they're harmful, rather I am simply curious as to what they are. Any ideas?
