Hi, I ran $ plutil -s ~/Library/Preferences/*.plist, and it reported that ~/Library/Preferences/com.appsc.data.plist was not proper XML format, or some such error message. I've moved the file to my desktop and rebooted. I ran $ plutil -s ~/Library/Preferences/*.plist again, no errors. Everything seems OK so far, but I was wondering how I can find out what this file does or what application owns it? -- Thanks, Charles You might be a redneck Jedi Knight if...
