Lockscreen Wallpaper
No matter what I change my desktop wallpaper to, my lockscreen wallpaper doesn't change. I have tried going to the Desktop Pictures folder in Library/Caches but each time, the lockscreen.png file automatically updated the image on it's own. It's just not what is actually being displayed on the lockscreen wallpaper. I have tried using apple wallpapers and custom photos but it doesn't seem to make a difference. Please help.
also the device listed underneath is wrong, it should be macbook pro.
MacBook Air 13″
