I am hoping that I can jump on board here for help as well.
Mine said that it was unable to complete the update. Then I got the panic. I snapped a photo on my iphone of what it said, and I can transcribe that if necessary.
I didn't know what to do and was in a rush, so I restored from Time Machine backup. Now I am back on 10.8.2.
Here is what I got just now from EtreCheck. Perhaps one of you can help me find the problem?
