10.8.4 upgrade stuck
My "Software Update..." tells me I need to upgrade to 10.8.4 (I'm currently on 10.8.3 on a Macbook Pro). I click Install and am told to restart, which I do. And when I get back from restarting, I'm still told to upgrade to 10.8.4. For some reason, I'm stuck in this loop. How do I break out of this and actually get upgraded to 10.8.4?
MacBook Pro, OS X Mountain Lion (10.8.3)
