I have had my MacBook Pro 15" with touchbar for a bit over two weeks now, and I've noticed, that when screen has been closed during some time, it has a tendency to be a bit hard to open at first, and it makes a popping sound from the hinges, which then doesn't reproduce itself the next times I do it. So it has to be closed for a period of time before it happens, and more importantly, it has to be cold - it only appears if the computer has been closed, and not been running. I've had issues with the hinges on the previous generation of Macbook Pro's, so I really do want to avoid any issues. What do you reckon? Is this simply just because it goes cold, or is this some kind of issue?
