Guys I own two Macbook Pros, a 15" and 17". These are the newest LED MBPs. Both computers seems to hang on shutdown. It seems to quit every program and just hangs like its doing something but its not. It doesn't happen all the time but it does it enough that its annoying. I have to manually shut it down and I don't think thats normal. I did some researching on this and it still seems like nobody has a clue why it does this. Any experts on this issue? Am I the only one that has this issue with two different MBPs???
