Done.

Mine too. None of the suggested workarounds change the pre-login boot up wallpaper for me

The pre-login boot wallpaper now loads from a sealed snapshot. It is not editable.

macOS today operates by separating the system files and the data files into two totally separate volumes. The system files are "sealed". It is, essentially, a read-only volume which Apple distributes. Since the hard disk is encrypted before you login, the computer does not have access to anything other than a little metadata associated with the accounts (username and a small icon and that's about it). Once you enter a password, the data volume can be decrypted. The computer then essentially "merges" the system files and data files together in real time like a zipper through a series of firmlinks.

macOS now boots in a state that is always fresh and identical. Only once you login do all the changes you've made (including wallpaper) become visible to the system.

So sad that this file is now a "sealed" file, especially since it wasn’t previously. I wouldn’t mind so much if it was less obnoxious.

It actually has been for quite a while. The last version of OS X where you could change this easily was Mojave, I believe. In Catalina the pre-login screen is just grey by default (which is how I think they all should be, honestly), although I think you could technically change it somehow—I don't recall. Catalina was sort of the last OS at the edge of this transition that still functioned like the Mac OS you might have known before it became fully iOS-ified. Catalina split the system volume from the data volume IIRC, but Big Sur was the first time Apple started signing and sealing the system volume. Howard Oakley has a great website (https://eclecticlight.co/) that details how macOS has changed in the last few iterations, and just how different it operates today from how it used to.

I actually think it's wild how much the operating system has changed at a fundamental level, and yet it still looks and feels somewhat familiar.

Have you tried Apple menu > System Settings >Users and Groups > Login Options > (unlock at the bottom) > set Automatic Login to Current User (admin) - guest user has to be off

This worked for me on my new MacBook Pro

Have you tried this?

Good as a workaround in some cases, but not for cases where login security is required.
