I recently followed @WhippsT instructions for changing the Login Window Wallpaper(find that here), and everything is working perfectly. However, once the computer goes to sleep, and then wakes up, it again uses the a blurred version of the existing desktop background, rather than the image I set.
Does anyone know if it is possible to change the lock screen as well, and if so, how could I go about doing so?
I'm hoping the only answer isn't the obvious one of changing the desktop wallpaper to match, as that won't be an option in my environment(Higher Ed).
@byrnese Apple has changed the way the Lock Screen is rendered. It no longer pulls from the default com.apple.desktop.admin.png... Instead, WindowServer generates the desktop screenshot and sets it as the background when you lock the screen. I'm not aware of any way to interrupt this process at the moment.
