    I have tried replacing the Mojave.heic in Library/Desktop Pictures, I looked into the Cache and so on... it seems imposible to get rid of that wallpaper.

    Anybody any ideas why the Desert Day Wallpaper always shows up (with FileVault enabled)

    Check some of the .car files in SystemAppearance.bundle file.

    You need ThemeEngine for that.

    Sorry not being more verbose, I am not in situation to type much.

    ny somewhere
    i mentioned this in another thread; am seeing that too, and i don't use filevault.

    the only way i've (so far) found to get rid of it (and only see my selected wallpaper) is to disable the 'guest' account, something i don't want to do (it's essential to 'find my mac').

    the mojave wallpaper also shows up behind "you shut down your computer because of a problem"...

    I suspect that the FileVault logon wallpaper is in the Recovery or Preboot volume. The main volume has not been unlocked yet so it cannot come from there.

    This^^^^. FileVault boot is a bare-bones setup. And doing a quick scan in that file system, not seeing any wallpaper elements. Just, basically, a pre-linked kernel, and the account/password information.
