I haven't experienced major issues with upgrading to 10.8.5 like a lot of users have, but one thing I've noticed is that the common wallpaper bug from 10.8.4 (or earlier?) is now even more persistence! Not only Apple has not acknowledged this, but they even made it worse! Deleting com.apple.desktop plist and restarting doesn't work anymore! This has really evolved from being a bug to a full grown disgusting insect VV, Anyone experiencing this?
