How do you actually change the wallpaper for the login screen on MacOS Monterey?
I don't like the default purple wallpaper and I can't seem to find any way to change it. I know how you change the desktop wallpaper in the System Preferences, but there doesn't seem to be any way to change the lock screen/ login screen wallpaper.
Has anyone found any workarounds for Monterey?
Many Thanks

if you are the sole user (not even a guest account) AND file vault is turned off you can go to System Preferences > Users & Groups > Login Options and set "Display login window as" to "List of users". then your login screen matches your desktop background.
if you are using file vault or have multiple users, the above will not work. if that's your situation, you will need to wait for apple to address this. it may be worth your time to send feedback directly to apple. Feedback - macOS - Apple.
Does not seem to work on Monterey 12.3.1
Hi - I'm running Monterrey 12.3.1, and it's working. I suggest that you check the filename on the png's that you place in the Library, and make sure that you're using png's; for sure, it won't work with jpg's. I placed my png's in multiple locations, just to make sure I hit one that would work - see above for how I did it. It's a silly solution, I suppose, but at least I'm rid of the annoying default image. Good luck!
Hi,
I dont have this path: /Libraries/Caches/Desktop Pictures/C6F2A043-F33D-4897-8F8F-433A71B0CA6D on my machine
I cant see /Libraries/ at all, they all just say /Library?
Am I missing something
This method did the trick for me and it works: https://www.howtoisolve.com/how-to-change-the-login-screen-background-mac-macbook/
On my machine (MacBook Air running 12.3.1) it is indeed
"Library", not "Libraries". Number of the final folder is also
different, but it may be different on every machine -- anyway, it's the
only numbered folder inside "Desktop Pictures". Full pathway is then
Macintosh HD/Library/Caches/Desktop Pictures/[whatever the folder number is].
So I found that you were correct, 12.3 fixed the screen for multiple users. Now that I'm on Monterey 12.4 it appears broken again. Any ideas? There are so many suggestions in this string from before 12.3 and not always for multiple users that I hesitate to start in again.
it's not the login screen that makes problems - it's that ugly startscreen called Chroma Red.heic:
i 've never had chosen it.
wich is not in Macintosh HD/Library/Caches/Desktop Pictures/ - here are the lockscreens, wich I can
change easily by only change the desktop pictures of every user.
the start screen is placed in
Macintosh HD/System//Library/Desktop Pictures/Chroma Red.heic
there are no user ID named folders and the files can't be changed in any way (system area)
Agreed, the default login in screen is aggressively ugly, an ambience killer if there ever was one. And you are correct, it would be much easier to clean pelican poop off an original Monet! Monterey doesn’t appear to be an artist friendly OS. I miss Steve.
I gave up. I will have to live with the girly screen.
This one is the one that works, Thank you very much!
even after mentioned in this block about 46 times:
this does not work for start screen on MacBook Pro with multiple users...
again and again - it doesn't work
it's a bug - apple has to do something
In my struggle with this thing, the one change that made it right was when I removed extra users. With one user, the proposed solution works - at least, for me.
Following all advice this thread did not produce any solutions. Spoke with Apple Support. Confirmed that the functionality is specific not the OS but the specific machine. e.g.
On some Mac models, the default desktop picture and login window background are based on the color or finish of the Mac. For example, the default desktop picture on a Space Gray MacBook Pro (2021) is "Chroma Red", and the default desktop picture on a Blue iMac (24-inch, M1, 2021) is "Hello Blue".
I totally agree! It is an abomination! So horrible to look at!!
