My new touch bar 2017 MBP case creaks (not the screen hinge) and I've read on here that it can be fixed by removing the screws from the bottom of the case and retightening making sure they're all even. If I did this would it void warranty (in the UK), would apple be able to tell the screws have been adjusted? If I'm fine to do this what size pentalobe screwdriver do I need? I've got the T6 but that's too big. Cheers.
