Has anyone gotten this to work with Mojave?If yes can you please share how to do this?
If you mean just changing the login picture, you just have to rename the picture you want to use as Mojave.heic and replace the one that already exists in /Library/Desktop Pictures

@gshackney Just tried that; seems to work when you set this and then do a log out. A restart you don't see this image.
I found you have to do this after.
If you have FileVault enabled, change a login option in System Preferences. For example, whether to show a list of users or name and password fields. Just change it back if you don't actually want it changed.
How do I change the login screen background in macOS Mojave?
