How to add custom message to Mac login screen


Apple has introduced a new feature to add custom text message to the login screen on Mac in its OS X 10.7 Lion version. Previously you were allowed to do this using some third party apps, but now Apple has added this feature officially to the devices running on Mac OS X 10.7 or later

By default, Mac’s login screen doesn’t feature anything other than the list of users. It means that Mac doesn’t allow any customization on its login screen, but using the two methods shown below you can add customized message on the Mac login screen.

How to add custom message to Mac login screen

1. Using system preferences

  • Launch system preferences from your Mac’s dock.
  • In the system preferences click on Security and privacy.
  • You need to authorize yourself using the lock screen present on left bottom corner by entering your username and password.
  • In the nex screen you will find four tabs, from that in the general tab enable Show message when screen is locked and then click on set lock message.
  • Now you can set the message to be displayed on the login screen.

If you face any problem in executing this method you can use the below method.

2. Using Terminal

  • Open terminal on your Mac and type the following command.
    sudo write /Library/Preferences/ LoginwindowText "Custom Text Here"
  • In the next screen replace the text message with you want to be displayed on Mac login screen.
