I switched between 3 different configurations of the 2016 Macbook Pro, both non-touch bar and touch bar models. All three of the Macbooks made a somewhat quiet noise when opened, sometimes when closed. It sometimes sounds like a click, but other times it's a bit louder and sounds like a sticky or creaky noise. It's hardly noticable, and is likely a non-issue. I'm just surprised that no one has reported this and that there are no forums anywhere on it. Does anyone else notice the noise? It sounds like it's coming from the right-side hinge (facing).
