I keep having this preference file showing as corrupt by Drive Genius. Whether it is impacting anything is yet to be determined as I am having other issues with my mac constantly restarting. Typically a short time after booting up and after opening a few programs. The preference file is /User/Library/Preferences/Y29tLmFwcGxlLnN5c3RlbXByZWZlcmVuY2Vz. I have tried to figure out what program or app. is creating it but with no success. Even if there is no real negative impact with having this pref. file, I still need to understand how to go about determining a file's creator,parent, or origin. Thanks.
