I went through four haswell rMBPs to get one with a good screen. I finally got one, but this one has a case that creaks constantly. It's driving me crazy! I've searched threads on this and found lots of people talking about possible fixes, including loosening the screws, tightening the screws, taking the bottom plate off and placing paper between the battery segments, putting silicon on the bottom plate edges, etc. However, there's rarely a definitive report as to whether this worked for more than a day or so. Does anyone have a technique they've used to successfully fix this annoyance? I tried to pull the bottom plate off myself, but my ifixit pentalobe 5 bit broke trying to loosen one of the screws, so I've got a new one on the way. Thought i'd ask while waiting.
