Installed via Software Update, no problems! App store loads up, but when you move the mouse around the screen to fast, it looks like it refreshes itself, but it still works.
Only problem I'm having is with the apps. Downloaded NovaBench and when it first loads up, it doesn't seem to recognize my graphic card (GeForce Galaxy 9400 GT). Try to run a test and it closes unexpectedly. This happened with another app where as soon as I started it, it randomly closed.
Any ideas?
