Change MacOS Monterey Login Screen Wallpaper

No it won't work with more than one user on the machine.

If you are seeing "Other..." on the login screen, you can't change the wallpaper. To disable "Other..." and thus see your wallpaper, see here:

This does not answer the question jeffreythefrog

The question is how to change the WALLPAPER (i.e. the BACKGROUND IMAGE) of the login screen.

I don't understand why your answer is "Apple recommended".

i think you need to read my reply again. it was apple recommended because it DIRECTLY addresses changing the LOGIN WINDOW background. you can ONLY make it MATCH your DESKTOP BACKGROUND ( not a different image than desktop background ) and ONLY if you are the SOLE USER and file vault MUST be turned off. if your setup is not exactly that, you need to send apple some feedback, and i am NOT apple.

My feedback to AppleSoft is that I refuse to move above Catalina OS, and that brands other than AppleSoft are looking more and more attractive the more AppleSoft behaves like those brands.

@jeffreythefrog's solution worked for me (if you want the same background as you desktop for your lock screen) - but, I had to toggle from my default setting "List of users" to "Name and password" then log out and back ind and change it back to "List of Users" and log out. Then my lock screen had the same image as my Desktop background.

AppleSoft hasn't existed since about 1978, so I doubt anyone will get that memo.

hi Ronni DC,

that is an excellent addition to this thread! yes, when changing system preferences, sometimes it takes a toggling off and on of the setting, and even sometimes a restart for the changes to take effect.

Here is a video on Youtube that explains how to easely change your lock screen picture with the one you want.

yes, that method does work as well. but for that to work, you need to turn off FileVault and also the mac needs to be a single user setup. (you can see in the video, they are single user setup) and if your machine is set up that way then you can just set "Display login window as:" to "List of users." to get the login window to match your desktop.

I followed @jeffreythefrog's instructions & took @Ronnie DC's advice of toggling between preferences.

I made myself the sole user (turned off guest account that was on), & switch settings to 'Name & Password'. I also went under 'Security & Privacy' & turned off fire vault. I then chose to 'Lock Screen'. My Lock Screen wallpaper finally matched my desktop (home screen)! I then turned fire vault back on.

However, I was greedy & wanted to see if I could also add back my guest account. I logged back in & went back to 'User Group & Settings.' I turned on the guest account & toggled again between 'List of Users' & 'Name & Password.' I then chose 'Lock Screen' again & ta-dah! I now have a pretty lock screen & a guest account.

Thank you so much @jeffreythefrog & @Ronnie DC!!

sorry to rain on your parade, but, that is expected behaviour, and does not address the topic of this thread. as you've seen, the "lock screen" will match whatever the desktop background is of the account you are logged into when you "lock" the screen. but the topic of this thread is the "login screen". that is the screen you get when you either restart the mac, or "log out" of an account. to change that requires a single user setup. not even a guest account.

I would like to know how to change my picture on the login screen also, and the background picture.

I am talking about the login screen When you first turn on your computer and log on. There is a picture above the login space. I would like to add my picture there, and change the default background as well. I see a post above that tells how to change the default background picture. Now I would like to put a picture of my avatar pic in place of the default pic.

That can't be done. It's built into the read only portion of the drive and can't be changed. Tell Apple what missing features you'd like restored or new features added to the system via Feedback - macOS - Apple.
