2015 MacBook Pro login issue.

[Subliminal87]

Fully updated sierra on a 2015 MacBook Pro.

The login screen is jacked. Some days it's a solid black color. Other days like today it's solid blue. The login pictures are there and are normal.

Any idea what the deal is with the background image?

If you can log in,try choose another image.

Where can you do that? I don't have it with me but from what I remember it only allows me to change the user icon and not the actual login background. It's been the default one.

Try changing desktop background a few times,if the problem is not solved,backup all your files,and reinstall MacOS.
