Their has been many posts about lose cover and uneven problems with the MacBooks.. I have notice by my pics and other that the problem is on the side by the Hard Drive, that is were my cover sticks up Anyway I was own the phone with Apple Support about this and I sent them a pic. After serval test he made me do he thinks that the Way the Hard Drive is place is causing this issues.. He belives over time it will become more lose and dirt or other items will get inside and cause problems with the battery or Hard Drive.. I having my sent back for a full refund because if this is true then every macbook or MacBook pro that came out Oct 14 will have the same problem What you guys think ????
