Since about the 3rd day after I got my macbook pro the computer has been making cracking sounds when I open it. When it first started it just simply made one clicking sound when the hinge is halfway open. Now however, When it is open it makes cracking sounds that don't stop ( open 15 cracking sounds per open). Is this a serious issue that I need to address with my local (and very mean) genius or is this issue not going to continue to get progressively worse. If this does continue to get worse will the hinge crack open? what is this worst that could happen?
