OS X El Capitan Lock Screen Black, Wallpaper Dissapears
I just upgraded to OS X El Capitan and I can't get my wallpaper to stay on the lock screen when I put my computer into sleep mode. Instead of the Usual blurred version of my desktop picture all I see is a black screen but I can still login just fine. All thats wrong is I can't see my wallpaper. When I unlock my computer the wallpaper goes back to normal. If you have a solution or the same problem is happening to you, let me know down below, Thanks.
MacBook Pro, OS X El Capitan (10.11.6), 13 Inch MacBook Pro, Mid-2009
