Can the image background be specified before a user logs in? I've searched for this online and all I found was numerous posts on how to change the user profile specific background image for the desktop.
I am using macOS Big Sur and presently after the operating system boots there is a orange / red background image displayed then the user login and password prompts, can this be changed?

It's no longer changeable by the user.
Simon yes it can. Search for custom Big Sur background or something similar I saw a post in this forum explaining how to change the screen when you first boot your computer.
Thank you Paul, I have tried that before I created the post, unfortunately all I could find was advice on how to change the desktop background image for a specific user login, which I know how to do, its the image background that is displayed before anyone logs in that I want to change.
Yes, but as I said, all of those replies are for after you have logged in and all detail what to do with the UUID, what I am asking for as I said is the screen before you login, is it possible to change that?
Ok. it was my understanding that it was before the login not after. I have my after login backgrounds rotating every 30mins using the feature built into the Desktop & Screen Saver preference pane. I know that isn't what you are looking for.

Simon I think you did. Sorry I miss understood the thread I posted the link to. I understood what you were asking. Poor implementation on my part. I would love to be able to change the pre login screen as well. The Big Sur screen is glaring compared the backgrounds I like and use on a regular basis. I hate having to reboot.
Didn’t I say before login and not relevant to the uuid? I want to change the screen which shows the login form, before any user has logged in.
Can the background which is displayed before login be changed?
