My 10.7.2 update (Safari, security update and itune) is taking forever to install. After Software update prompts me to restart my computer, I clicked restart and a grey horizontal window pompts up that says "Installing 3 items" and a sentence below that says "This may take a few minutes, do not shut down your computer" However, this message has been there for like 3 hours+. Anyone know why? I have a very fast network, e.g. I can watch like 720p resolution on youtube without waiting for stream. I am running mac OS X lion on early 2011 15" macbook pro. Thanks!
