Hi, I want to set up my desktop wallpaper as my lock/login screen wallpaper. I have selected a wallpaper from the Mac gallery and have also checked the Caches folder where I have the same image but in blurred format and named as "com.apple.desktop.admin.png". However, my lock/login screen appears as a dark grey color background, but I see the wallpaper when I restart or switch on the computer. Any advice how to resolve this issue? Thanks.
