Just completed the Beta 2 update through the App Store.
Upon logging in the Dock did not show so I rebooted the machine one more time. This time the Dock shows but the App Icons are the paper and Pencil. When I try to open one it tells me the App is Damaged. I am able to open a finder window but when I go to the Applications folder there was nothing there for 15min and now there a some of my applications showing with the Progress circle spinning in the bottom right. When I try to scoll in the Applications folder it just show the pretty new beachball.
This is an iMac 27" Retina
