I have updated my wallpaper recently and now when I restart my computer or logout, my old wallpaper still shows (blurred, obviously) on the login screen. When I login, my new wallpaper is there. Is there a way to fix this?

Unfortunately this possible duplicate does not address my issue: How do I change the login screen background in macOS Mojave? This is not after updating to Mojave OS. I have not updated to it. So I do not have a "Mojave.heic"

  • You can replace /Library/Caches/com.apple.desktop.admin.png with your own file, making sure it's sized to exactly match your screen resolution. My program in my answer to the other question can actually do all that for you -- it checks the OS version and handles both pre- and post-Mojave. – SilverWolf Jan 6 '19 at 16:13
