Can I change login screen with OS Monterey

I wouldn't write them off just yet. Send a complaint in. The might just fix it.

I've been through every solution I could find and the only thing that worked was turning off file vault. Sad, Apple. Very sad.

Most of the instructions I've seen only works on single user Macs. I have multiple users on a MacPro. I'm guessing the UUID locks the login screen to a single user. If there were a way to determine the UUID of "root" that might help.

I tried to do this manipulation, it doesn't work and after the manipulation my MacBook Pro refused to shut down. I had to delete the folders to come back to a normal operation with the possibility to shut down my Mac without having to force it by pressing 10 seconds on the power button

It is the login background image that I want to change, not the desktop image.

If I read your instructions correctly when I change the desktop it instantly changes but I do not want to change my beach scene desktop background. It is the Monterey color login backdrop that I do not care for. Actually I have an orange Mac 24 and like that color for the login.

thanks

Thank heavens, I am not alone in Chroma Red Login Purgatory. Likewise, I have done a number of advice on searches and it won't go away. I've even managed to copy over the Chroma Red.heic file with the Monterey default heic file and still it remains.

Should this specific issue be submitted as a new fresh discussion thread?

I'm on MacbookPro M1max 16" on OSX 12.0.1 and I have exactly this configuration on the settings: 1) FileVault is turned off, 2) I am the only user and guest user is turned off AND 3) in the users & groups preference pane I have "Display login window as List of users" checked .... and it doesn't work ! the login screen image is not my wallpaper and it's not the /System/Library/Desktop Pictures/Monterey Graphic.heic image either. instead I always have /System/Library/Desktop Pictures/Chroma Red.heic in the background of the login screen which is absolutely horrible !

You are wrong. If you go in through system preference>desktop and screen saver, click on desktop, you get choices, sure. But they just won't apply in Monterey. You can choose what you like, it will not switch out of this horrible mauve valley screen, which comes with Monterey. Can someone produce a fix for this soon, please?

Do I navigate to the Go to /Library/Caches/Desktop Pictures. from the "advanced options" from User & Groups in Systems Preferences? The "warning" sign made me hesitant to do anything. Has anyone reported success on this protocol (to change the hideous login screen arty thing) when system has multiple users?

Thank you for this, it didn't work the first time for me, but did eventually after playing around a bit.

I followed steps 1-7 exactly as written but wasn't sure what to do about the lockscreen.png text which appears between Steps 7 and 8. Turns out there is nothing to do; the system creates that file on its own after a restart based on the image selected in Step 11.

Still, my chosen lock screen didn't appear after Step 12.

Here's the magic - I then selected Lock Screen from the  menu and it switched to the lock screen with my chosen image! I then restarted again to confirm, and sure enough, my M1 MBP running MacOS Monterey now launches my screen.

Thanks again!

He is taking about the screen you get at start-up. Since Big Sur, instead of a photo is a painted landscape with horrible colours.

Have you ever started an iMac or a MacBook? What is the first image that you see BEFORE logging in?

I believe you are confusing "login screen" and "startup screen". The pink monterey image is in "login screen" - please see attached image:

You can see that it's the pink lockscreen image, however when I log out of the computer completely and re-start, this is what's in the login screen and this is what we're trying to change:

This image is not in the desktop pictures folder. It is the login screen upon re-start/log out. Our question is WHERE is this image and HOW do we change it....

Looking for this answer.

This is not straightforward. I suggest that if someone has a problem with this screen they should (a) read SeptimusHarding above and include in their post whether or not:

• FileVault is turned off
• Display login window is set to "List of users"
• You are the only user or there are others
• Guest User is disabled
• "Display login in the users & groups preference pane you have window as List of users" checked, and not checked "name and password".

and (b) be clear which screen they are referring to - the "login screen" or "startup screen" as described by showbizmanager above.

Thanks

There seem to be a few of us who are stuck with this god-awful Chroma Red login screen. (While I sympathize with people who dislike the default Monterey login screen, I really have to ask them to hold our beers on this case because, good grief, is that Chroma Red screen jarring, as fellow sufferers, "showbizmanager" and "jjcliff" have demonstrated!)

At this point, it may probably be best for those of us trapped on the "Chroma Red" login screen to start our own topic. It seems to be different than the Pink Canyon that others are suffering through so that they can resolve their problem and we can resolve ours.

(Brief follow-up: I have added this apparently divergent problem here: "Monterey Login Screen is Stuck on Chroma Red (different than the Pink Monterey Valley screen!)". Best of luck to the people stuck on the customizable background problem.)
