Tried searching for this but cannot seem to find a topic specifically for the 12-inch. I apologize if I missed it. Finally got my 12-inch MacBook today, just the base model, after much debate in my head. I finally figured it's better than the iPad Pro for me since I can do more with it. I might be in the minority in saying that the keyboard is what sold me on this (plus of course the wonderful screen). I just don't make any typing mistakes as I used to using these keys. Anyway, after the honeymoon period, I noticed that there is a slight rattle on mine coming from inside the keyboard base, when I tilt the unit left and right. Sounds like something has a give inside for some reason. Curious, I also checked the demo units at BestBuy and the Apple Store and noticed a similar 'tock' sound. It's not really bothersome to me but it's kinda odd and unsettling to know that there might be something loose inside. Has anyone noticed this on theirs? Please say yes...hehe...thanks guys and gals.
