My M2 Air made a slight clicking noise when closing it when it was new. It was something that was barely noticeable. I decided not to mess with the bottom plate screws, and after a few months it went away on its own. It may not be the same thing others having the issue reported, but it was similar. It has long since gone away, and no longer occurs. I knew I was under warranty and if it worsened, or I felt that it may affect connections from the base to the display, I would just take it in. But, it disappeared and I cannot reproduce it. For me it seemed almost as if something needed to be broken in, or acclimatized. However, if it is really bothersome or loud, it definitely should be looked at. My machine has been perfect since and hands down the best Mac I’ve ever had.
