So today I was using my 2016 13" MBP as usual. There is this issue with my spacebar key; it is getting like jammed on the right side, to the point where sometimes you press it and it feels like it isnt pushing down at all. Sometimes it doesn't work when you press it from that side. And it seems to come and go, like it will randomly feel fine and then feel jammed. It first popped up like a few weeks ago, and then went away, and now it is recently been doing it again. I noticed it with "R" key about a month or so as well, but it has since been normal. So as I was looking to see if maybe the key was stuck or something, I picked up the MacBook Pro and noticed this rattling noise as if something was loose inside. It only does this if I move it from right to left, not backward or forward. Is this just the fan, cause I haven't noticed it before? Has anyone had these issues and is it something I should take it to the Genius Bar for?
