Can I change login screen with OS Monterey

This is the same problem that Apple had with those disgusting orange and red colors for BigSur. If the machine has more than one user, one can't change the log in screen where one selects the user to log in.

Shame on you Apple. Such great products spoiled by stupid little things which ought to be so easy to solve.

Don't bother sending Apple feedback - they don't listen because they know best!!.

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

This worked for me:

• Right-click on your desktop and go for Change Desktop Background.
• The Desktop & Screen Saver settings open up. Tap on the desired wallpaper, available under Dynamic Desktop.
• Important: If the background image fails to change, check if a small cloud icon with an arrow pointing downwards is displayed, in the top-right corner of the thumbnail.
• Fix: The same icon is also displayed next to the wallpaper’s name. Click it and the desktop will start downloading. It will show up as a background as soon as the download completes.

It’s Monterey Canyon. It’s underwater.

I am having a similar problem, except my login/Lock Screen is stuck on the CHROMA RED wallpaper.

When I login, the wallpaper is set to the Monterey. The purple default one. But if I restart my MBP and get to the login, I'm seeing this ugly red one. I tried all the tricks on YouTube, and the ones listed here. Nothing works to change it.

The CHROMA RED, for reference:

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

How did you do that?

• I am running macOS Monterey.

• I turned off the 'Guest User' Account under - System Preferences/Users & Groups - (This is important - I believe that you can only have one user account active for your custom Lock Screen image to show up)

• I searched for this folder - /Library/Caches/Desktop Pictures

• Your UUID folder (crazy long name of letter and numbers) is in the above folder you searched for.

• Find this file 'lockscreen.png', and replace it with your image and the same name - 'lockscreen.png'

• Restart your Mac

This doesn't work.

SAME with me. I was on apple support for several hours this morning and they ended up escalating to the engineering team. Glad I am not the only one.

I can't find the "Desktop Pictures" folder in either the HD Library, or the user library....

Additionally, a search for lockscreen.png yields no results.

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?
