I've had my new macbook pro over 2 weeks now but I've noticed a problem with it in the last day or two. The bottom case creaks. It seems to do it on the lower half, mostly on the left side. When i lifted it up, the corner cracked too. I don't know if the case is flexing or if its normal. I've tried looking around and some people say it's normal, but some people say it's not. Ive been prodding it all night. Really don't know what to do. I think you get a 30 day return with the UK Apple online store. Should I book a genius appointment? Knowing my luck it probably wont creak when I show them. And I'll look a right numpty. My mid 2010 macbook doesn't creak, so I don't know if I'm being OCD about it or not.
