Add Welcome Message to Your Mac [Terminal]

In your Mac login window, you can add a welcome message right below the Apple and System Status. You only need to perform this following command line:

sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText "Hi, I am Mac"

Characters inside double quote will be displayed as your welcome message. I know you will try this and I also know that you will want to delete it as soon as you've finished trying. So, here is the command line to delete your Mac welcome message:

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

Someday, you can consider putting your username and password as the welcome message. No one will know, except me, you and other readers of UsingMac.com.
