Audible "POP" sound from new MBP -- strong enough to feel it through my desk. Anyone else?

    This is super weird.

    I haven't seen it until a couple of days ago and its totally random. It's loud like a metallic POP or CLICK sound and its powerful enough to be felt through my table.

    Anyone else experiencing something like this?

    For the record, I love my new rMBP so I'm not just looking for something wrong with it.

    Yes! Exact same issue on my end. I have yet to install Windows, so I'm quite sure my speakers aren't blown.

    My speakers are also perfectly fine. I have the 15", 2.9, 1TB, 460.

    I'm wondering if the fans are getting stuck or something but the iStat menus show a continuous 2000-3000 rpm with no stutter.

    So glad to know I'm not alone. I really wonder WTF is going on. It's super weird.

    Yes I though I was the only one it has been driving me crazy! I love every thing else about it though.

    Remove the bottom case and put your ear up to the laptop.

    Turn on the laptop.

    Figure out where the sound came from.

    I just found out the if I push in on the lower part on the back of the display I can hear similar sound. I don't know if its the same noise I just it was worth a mention.

    Mine does as well. It is similar although the real sound is a bit more violent.

    This makes me think it must be related to the spring/hinge mechanism in some way...

    I hope so it would be a whole lot better than something internal.

    There is another thread about this, but calling it a creak. My 15/2.9/460 seemed to do it when it got warm while running on battery power. Sometimes it clicked/creaked when I moved my hand position while resting on the palm area, but other times it did it spontaneously without my hands even touching the machine. Sounded almost like an non-ssd hard drive that was starting to fail. Except these don't have spinning drives so that would be crazy :)

    I ended up returning mine over this. Currently back in line waiting for a replacement to give it another try.

    Yes! It seriously sounds exactly like a normal HDD starting to fail.

    It's also happening spontaneously to me as well! Most of the time I'm just watching a video or reading something so my hands aren't even near the keyboard... What on earth...

    Do you think the MR admins can merge the other thread or merge this one into that one?

    Could it be metal expanding or contracting from temperature?
    We've got to pin this down.

    From that other thread, it's looks like a thermal metal thing. The metal bottom is very thin (but hopefully strong ) Could be that.

    Exactly.

    There are multiple threads about this so its seemingly a widespread issue.

    I think none of us are freaking out about the noise but it is weird AF. It's a pretty powerful click/pop/creak noise to be felt through my working table (thus, it seems to be related to the hinge -- I'm sure there are powerful springs in there).

    This guy also appears to be having the same issue as us in a different thread: http://forums.macrumors.com/threads/spring-type-sound-on-bottom-casing.2017653/#post-23981025

    Maybe you don't believe me but this pop/click/tick noise can be due to capacitors and coils components inside your new MBP. Yes, it is random and it absolutely normal because CPU, RAM and SSD are getting faster. For example you can hear your SSD or the electronic components around the CPU or in your Ram when move a lot of files or compress a large folder. So in my opinion that noise is due to electronic components.
    There are a lot of papers on internet about this phenomenon ( Coil Whine, Capacitor hiss, Power supply hiss sound...) and you can see a lot of forum about people complain hissing sound from their electronics and Macbook/iPhone etc...
    That's just my opinion based on years and years of experience in the electronic field and I am not saying that it cannot be due to assembly or anything else, just consider this possibility.

    Hope this helps you.

    Hello, i have the new 2016 macbook pro 15" with the touch bar for about 2 weeks and i have some problems with it. one of them is when i shake it side to side i hear a rattling sound (i found out that is the light panel behind the display) and i want to ask if other 2016 mackbooks have this problem to?
    The second problem, that is more annoying is that i hear a random popping/cracking noise when i use the laptop (it usually happens when the laptop is cold and i am using intense programs and its start heating up). I also saw that this problem comes from the display/hinge because when it gets hot and i slightly touch the display it make the same popping/cracking sound but not that loud. Is this normal? are other 2016 macbook owners have this problem? should i take it back to the apple store to exchange it for a new one?(i am afraid that a new one is going to have other problems like the gpu or the battery)
