With Lion’s debut, Apple ushered in a new login screen that not only looks different but allows for a customized message. The latter actually serves a practical purpose (or could proclaim your love for your sweetie, your Mac or your dog—your choice) So, how do you create that?
- Open System Preferences
- Click Security and Privacy
- Click the General tab
(You may need to unlock your preferences by clicking the lock icon and entering your Admin password) - Check “Show a message when the screen is locked.” and type in your custom message
Note that you’ll have to have automatic user login disabled to see your message the next time you start up.
