Mac Customized Message Method #1 –

The method is clearly explained by Bryan Clark of TheNextWeb. He takes the example of his MacBook, if lost or stolen, the person/thief could see the customized message with his contact details for returning his laptop.
Basically, this method involves simple click steps and it is as follows –

  • Firstly, you must click on the Apple icon, which is located at the top left of your screen.
  • Now you must select System Preferences > Security &Privacy.

  • Under the General tab, select the lock icon which is at the bottom of your screen.
  • You will have to enter your credentials, i.e. Admin name and Password.
  • Once again under the General tab, check the box that says “Show a message when the screen is locked” and then click “Set Lock Message…“.

  • Now just add on your customized message in the text field and then click on OK.

That’s it. Now your lock screen will automatically have your message; without any restarting procedures of your device.

Mac Customized Message Method #2 –

This method involves certain amount of coding in it. But not to worry, it is in fact just 2 lines of easy coding language. It is as follows –

  1. Firstly, you will have to click on Application > Utilities.
  2. Now you would have to choose Terminal.
  3. This is the final step, wherein you will have to type in the code/command –
sudo write /Library/Preferences/com.apple.loginwindow LoginwindowText "Custom Text Here"

Note:- you have to replace the “Custom Text Here” with the message you want to display on your login screen.

In order to edit or delete your customized text, then you can use this code/command –

sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText ""

Normally, the customized message is used much like how Bryan used, i.e. for lost/stolen scenarios. But at times, you could also use certain comical messages or just few quotes for either yourself or for your friends/family/strangers to check out once they open your Mac.
