Can I change login screen with OS Monterey

I have the same problem, except it's a different wallpaper (the light variant of the "Chroma Red" wallpaper). I tried the "UUID\lockscreen.png" thing, but the file was already there and already set to my current (different) wallpaper. Tried changing it anyway, but the login wallpaper is still stubbornly set to that "Chroma Red" wallpaper.

It must be cached somewhere on the drive, but I haven't been able to find where. (I never even set this as my wallpaper, so it's a mystery where/when this was chosen in the first place.)

With all due respect to "APPLE," users should not have to be figuring out workarounds to solve this desire to change the login screen on their respective Apple devices, right? There should be no questions whether you are in Vault mode or not; it should just work. However, it does not!

Then to leave the problem in the hands of the apple discussion/community is a copout.

Thanks for trying to help. I did follow the instructions up to 59 seconds, but I did not see any "Advanced Options" on the Users & Groups preferences. I did find the UUID on the disk utility, but the rest of the instructions were complicated and I gave up. I guess I can live with the Monterey screen; it does not last long! Thanks again.

Hi all,

I'm curious myself as to how the default login background photo is selected on macOS. I'm on an M1 MacBook Air running macOS Monterey (12.1), with FileVault enabled. My login screen background is automatically set to the light-mode Monterey graphic (pink and purple shades).

Does anyone else get a different image when they have FileVault enabled (in System Preferences -> Security and Privacy) and they restart their Mac? I'm particularly interested in what happens on an M1 iMac and on the new 14" and 16" MacBook Pros.

This info could help in finding out how macOS chooses which background to display, and how to change it.

Apple was founded on user choice... the computer for the rest of us. I’m a Boomer,so I go waaaaaay back, and I’ve only ever used Apple, but now this embarrassing, hideous, boot screen has been locked in and I am sure there will be no change because we are now to be told what we will accept and how we will operate our devices. I feel betrayed and quite sad that AppleSoft has turned its back on its founding principles.

<--that worked for me. thx.

actually, i had no problems with my preferred login screen after I updated from Big Sur. It stayed how I wanted it. However, the background did revert to the default pink/purple Monterey pic when I cleared out all my caches to do some troubleshooting related to another matter (USB hangs).

thanks again for re-posting this solution.

How I despise this login screen, at least past ones had nice images of landscapes I can indulge in, but this dated looking monstrosity is like something out of the days when we first launched OSX. It's ugly and it was a terrible, terrible decision by Apple.

I guess I'm going to be the peculiar one here, but I don't even mind the new colors on the login screen. But even if I didn't like them, it's just the login screen, for Pete's sake, how long do we look at that, maybe one second max? There must be more pressing issues to deal with in these Discussions ...

When I buy an appliance that allows personalization, I want the manufacturer to allow me the freedom to continue making the changes I have made in the past.

Apple is not the only business that has taken away owner rights. Owners have no choice on Microsoft updates (even when they suck), and few Android owners have been able to avoid updates as well.

After all, and complain about it myself since Big Sur (same ugly screen, less complained, just different colors….), I admit I concur to what you are raising here. True, it’s minor compared to fact I always need to wait about 9 months so many programs I use finally comply….

Nevertheless, even though “art” is a very subjective matter, if security is involved in that decision to “remove” capability to change that screen, it is the second year Apple is providing such an ugly design. Never wondered about modifying Catalina or previous default screens…

i’ve upgraded the software and red chroma is still there when I log out completely, turn off the computer, turn the computer on again and it’s there on the very first screen. You will not get this screen unless you log out shut down the computer and turn it on again. if you simply log out you will get the Monterey login screen.

With the upgrade to 12.2.1, suddenly, my MacBook Pro is now loading the wallpaper I originally selected rather than the default purple rainbow of Mac OS 12. Don't know why this type of thing happens. Couldn't get it to do this before when a did a wipe and clean install of Mac OS 12 before.

I’m still on Catalina, simply and solely because I refuse to accept a login screen that looks like an adolescent female's bedroom.

Have you tried changing the login screen under Big Sur?

It’s interesting that my last two comments were deleted... apparently because I use the word AppleSoft

Pardon me, but I don't understand what the big deal is with the login screen. I mean... how long are you staring at it?? Log in, and it's gone! Are the colors that offending to you? How often do you log out? I guess if you have multiple users on the same computer it could happen often, but as the only user on any of my computers, I can deal with looking at the login screen for the 4 or 5 seconds it takes me to log in. Sorry... I'll step off my soap box now. 😀

This thread has been going on for a while about this topic so, while it doesn't bother you, it obviously bothers other people, myself included. As for myself, I really don't like those colors and since I have to reboot my workstation often for work, I'd like to be able to change them considering how much I paid for my laptop. I bought and meticulously applied a really nice woodgrain skin for my MacBook that I love and yet after a reboot and after I go for a coffee there is my bright pink and purple computer waiting for me. Here I thought everyone is for personal preference these days right. Macs are supposed to be the "artists computer" yet I can't change something super simple like a login screen that I am forced to look at 25 times a day.
