Custom Login Message Jaguar is an Applescript Studio application that can be used to quickly edit the com.apple.loginwindow.plist file in /Library/Preferences to add a custom message to the login panel in Mac OS X.
To use Custom Login Message type in the message you'd like to include in your login panel, click the lock icon to enter your administrative password, then click the Change Login Message button to perform the action.
If you want to remove a custom login message, just delete all text from the window and perform the action.
