The option to Add Custom Message to the Login Screen on Mac was introduced by Apple with macOS X 10.7 Lion update.
This feature can be used to add an Inspirational Quote, Daily Reminder or your phone number, so that anyone who finds your Mac is able to contact you, in case you happen to forget or misplace your Mac somewhere.
While it is common for users to personalize the Login Screen of their MacBook by Changing Login Screen Wallpaper, the option to Add a Custom Message to the Login Screen is less commonly used.
