Can someone help me with this? I want to update to 10.8.2. I see that it's now through the app store, which is fine if it was working. When I click update all it says iPhoto can't be update because I run 10.8.1, but for whatever reason, even though it says .2 is installed, it's not. I restarted it several times, I always get the same screen. How can I install this?
