Add a Message to the Login and Lock Screen in Mac OS X Lion
Mac OS X Lion brings a nice new feature to login and lock screens that allow you to display a message underneath the login panel. This is visible to everyone and it makes for a great place to put either a generic personalization or better yet, a lost & found message.
How to Add a Login & Lock Screen Message to OS X Lion
Note that for the lock screen message to be displayed you also must have the ‘Require password’ feature turned on in the Security panel, then:
- Open up System Preferences and click on the “Security & Privacy” icon
- Select the “General” tab and then click the little lock icon in the lower left corner of the window, enter the admin password when asked
- Check the button next to “Show a message when the screen is locked” and type your login and lock screen message in the box below
- Click the lock icon again to set the changes and close out System Preferences
If you want to confirm the change, activate a screen saver with a sleep corner or lock your Mac screen, just be sure that you require a password or you won’t see your message. You can see what this looks like in the screenshot above and the closeup image below:
Having a message on your lock screen is a great loss prevention and general anti-theft measure, since anyone who gets the Mac into their hands later will see the message and if they have a conscience, will hopefully call the number you set on the screen. This could also help if you ever accidentally misplaced a Mac laptop, and is a great addition to setting an “If Found” message as the iPhone lock screen wallpaper which was suggested by Apple a few years ago.
For those wondering, the screenshot background is the Fliqlo flip-clock screen saver, and it works fine in OS X 10.7.
I like this one a lot. I learn something new every day here, thanks.
“and if they have a conscious,”
If they have a conscious what? What is it and why does it need to be awake?
Well I guess consciousness is required to have a conscience, right? Thanks for pointing out the typo!
I work for a school and I miss the ability to ask users to click on the login screen for there ip address. Is there a way to add this function back to the login screen?
How did you get the time in the back, thanks?
It’s from the flip clock screensaver Fliqlo
How did you get the Flip Clock?
gr8 .. woooooooooooosh .. Ooo`WOoooooooop :]
Just wondering how you changed your login window background, I know it’s fliqlo but does it update? Or is it just a static image?
It updates and runs like a normal screen saver, that’s actually the lock screen though and not the login window. But you raise a good question, so we will look into the ability to set a screen saver as the login window background, that would be a cool trick.
This feature’s also attainable on OS10.6 and lower – using CLi – (i.e in Terminal):-
sudo defaults write /Library/Preferences/com.apple.loginwindow LoginwindowText “Prop of OSXDaily.com, if found call 415-555-1212″
NB: CLi must all be on one line!
[...] on the clock is somewhat unintuitive. Ideally, you could show this data in the same way you can add a message to the Lion login screen, but there are currently no known methods to do that unless you want to just manually add the [...]
