    Hi, I just got rMBP 15" 2014 model and noticed that when the laptop is sitting on my lap and I apply pressure on the palm rests, something clicks. I flipped the laptop around and started applying light pressure. When I apply pressure on the bottom panel near the center horizontally and up closer to the screen hinge vertically, it clicks consistently.

    Has anyone else experienced such a phenomenon and, if so, what did you do about it? I literally received this computer yesterday and feel like this shouldn't be happening. Wondering if it's an overall design flaw with the 2014 15" model or unibody 15" in general. Thanks!

    I've had this for around 2-3 years on my 2011 MacBook Pro, which is a non-retina, so I'm surprised the Retina MBPs also suffer from this. Mine always used to creak when I used it on my lap and had my palm resting on the MBP beside the trackpad. Was very annoying hearing this 'creaking'/ringing/squeeking noise when very light pressure was applied.

    I don't know what I did, but the noise has gone now and I no longer hear it. It's quite a common problem. The issue is related to the 'grounding bar' on the MBP which has a spring that creaks under pressure or when tapped against the back plate/cover of the base of the MBP. Try loosening or taking off your cover and putting it back on. Here's a Youtube video of the sound and how to identify the grounding bar: https://www.youtube.com/watch?v=0uuhLyxKjRo


    The issue on the Retina MacBook Pros however seem to do with some other springs, so worth having a look at these threads:

    My 2014 13" rMBP does this on the bottom case. If I flip it over, and start poking it I can hear it. I had something like this happen back in 2012 and the only resolution the Genius could offer me was to reseat the bottom case. It is s very common issue. I just ignore it... Those little pogo pin springs can be oiled using sewing machine oil (nonconductive) and the problem will go away for the forseable future.

    Thanks for the replies! I'll probably go to the Apple store and have them look at it tomorrow. I want to ignore it and forget about it but every time the laptop is on my lap and I put pressure on the palm rests and ease up, it clicks. Too annoying to put up with for a $2000+ machine.

    I'm still within the 14-day return window so I shouldn't have a problem getting a replacement if need be.

    My 15″ rMBP made the creaking sound, so I got a pentalobe screwdriver and reseated the back cover. Just took the bottom plate off, lined it up again, and tightened it down where it came from. No more creaking.

    They will most certainly reseat the bottom. Heck, ask them to apply a bit of lubrication to those springs ;) other than that, there's not much that can be done. Honestly, if your machine is otherwise perfect, I would just live with it. You risk playing the return games and could end up getting a machine with far worse defects. Just my 2 cents
