Display a message in the Mac login window
You can add a short message to the login window that is displayed when your Mac is locked. The message can be anything appropriate to users attempting to log in — for example, to provide information for guest users. The message can also act as a virtual engraving, to provide contact information for a misplaced computer.
On your Mac, choose Apple menu > System Settings, then click Lock Screen in the sidebar. (You may need to scroll down.)
Turn on “Show message when locked”, then click Set.
Enter the message you want to display in the login window, then click OK.
Thanks for your feedback.
