Hey guys I'm a first time poster here. I have the Public Beta 2 for Yosemite on my Late 2011 MBP. This beta is probably less stable than the first PB. However, there is this bug that is really annoying and no one else seemed to have mentioned in in previous threads. Every time I boot my Macbook Pro, the login screen appears with a white background. Everyone else seems to have their actual wallpaper blurred in the log in screen which is how it's suppose to be. Mine is just a white screen with the log in info. So after it logs in and loads 100% then thats when my wallpaper comes in again. The picture attached shows what it looks like all the way until it loads 100%. Is there any way to like reset the log in settings files or something? It's not something major but just very annoying.
