AppLocker only works when launching an app. If an app is open, and you come back to it, it will still be in the unlocked state. If you want to lock your apps on a day-to-day basis, make sure to quit the app when you walk away from your Mac. You can also use the shortcut “Command” with “+” to instantly lock all apps.

Mac custom messages have enough space for informative lock screen messages without any word limit. The message itself can be anything: a message to return your stolen Mac to you or any information for guest users.

How to Add a Custom Message to Mac Lock Screen

Step #1. On your Mac, Click on the Apple icon and then select System Preferences from the Menu.

Summing up…

Apple products come with stronger security features, and therefore, there is little chance of your Mac getting stolen. However, this feature comes handy when two users are working one after another on the same Mac. The first user can leave a message for the second user, who can read it and work accordingly.
