Have you ever noticed a Mac showing a custom “Welcome Message” before you can login, or have you ever accepted any fair computer usage policy before you can log into a Mac. Starting from OS X 10.7 Lion, Mac users can add a custom text message or a banner to Mac login screen. This could be very helpful for a lab or work computer to convey an important message or a fare usage policy. Basically, there are two types of messages that can be shown to an end user, first is just a text message showing at the bottom of the login screen and second could be a kind of usage agreement banner with texts and images that a user must agree before he/she can logs into the computer. Setting up such a custom message or banner is as simple as copying a text and pasting it to a file. You can also add a custom message to be displayed when your Mac is locked or screen saver starts. This post will focus on how to add a custom message to your macOS Login Screen?

The login message can also be used to display the contact information of Mac owner, which can be helpful in case the machine is lost or stolen. So, the message could be anything from tips of the day, an inspirational quote, contact information, computer hardware information to a computer usage agreement. Computer hardware information can be used to help identify a Mac in a domain network or to help an instructor to choose the right device in a lab before starting any test or demonstration exercise.
