Lockscreen Wallpaper not showing correctly after clean install of macOS Ventura via backup of Time Machine

Hello,


I just clean installed macOS Ventura 13.6 and did migrate all information via Time Machine Backup, the problem im having is that I have is that the login lock screen wallpaper is not showing the correct wallpaper, I do not have FileVault activated, so It should show the wallpaper that I have selected on the macOS, it should be same.


When I boot up the Mac on the login screen it shows a default wallpaper of Ventura ("white mode") and as I have another wallpaper selected, it should show up the wallpaper that I have selected blurred in the login screen when I boot up the Mac.


I can switch to any wallpaper in macOS but login screen wallpaper is showing always the "white" default ventura wallpaper.


Any help?

Thank you!

FINALLY I've managed to find a fix, that for me it worked!


Fix to login screen not showing correctly on Mac:


1 - Copy USER UUID value/numbers, not the hardware UUID, the users UUID, by typing the following in Terminal: 

dscl /Search -read "/Users/$USER" GeneratedUID


2 - Copy the UUID number


3 - Create a folder on “ /Library/Caches “ called “ Desktop Pictures “


4 - Create a folder inside “ Desktop Pictures “ with the UUID numbers


5 - Change the wallpaper on macOS preferences


6 - Reboot

The Key Element that may have been overlooked and I quote from that link


" if you are the sole user (not even a guest account) AND file vault is turned off you can go to System Settings, in the Lock Screen tab,  and set "Login window shows" to "List of users". ➡️ then your login screen matches your desktop background. ⬅️
