When I start up my NEW mac book pro computer, the log in screen background is different than the background I selected for my desktop. How can I change the log in screen background? For some reason, even when I have followed steps I have found in mac book pro tips online, the log in screen background continually reverts to the default (looks like a toucan or penguin all pieced together - not at all what I want). Thank you.

There is no user preferences for this until you get to your user login.

Change the desktop picture (background) on your Mac - Apple ...
