Popping Sound, MBP 2016

I have my MacBook Pro 13" with touchbar since January and i have noticed this Issue since day one I contacted apple and they suggested software solutions of course it didn't help I also searched the web to see if anyone else does have this issue i found this discussion back then it had just 2 pages now it has 19 and I noticed many people are finding this issue ... I also visited the Genius Bar without any solution then I decided to work with it and try to ignore the sound and I think after al those months its because of the Aluminium when I am putting the ,a book in my bag after a work session I normally grab it from the top when closed and every time i hear the same noise a popping while shut down it's the same sound that I hear when it's on and open I flourish want you can try it out after finishing just press a little on the upper bottom part in the area under the trackpad and you will hear it please tell me if anyone noticed it after trying ...

Same issue here. MBP 2.7GHz, 512SSD, Radeon 455. Didn't happen for the first month. Now is happening over ten times a day. Happens seemingly spontaneously. I'm not even using youtube or anything ... just normal web browsing and coding. Macbook does not appear to be hot at all and certainly isn't under heavy load of any sort.

Hi!

Just have the same thing with my secondhand MBP 15 early 2013(!!).

The loud pop from speakers only, usually when laptop turn on after the rest. Like this: Macbook Pro 2016 15" Pop/ Click 1 - YouTube

No pops form hing or display.

This was start after I install 10.12.3 3 days ago, and not noticed with previous ElCap.

So I'm really convinced that the problem is audio drivers replacing with Sierra update.

Can't try to reinstall ElCap for now, unfortunately, but maybe someone want to try...

PS: sorry for my English, guys.

I have the same sound developed in my 5-year old MBP computer. Sierra 10.12.5 recently installed and sound developed after that. Took it to Apple Store; they replaced a "bracket" and could find nothing else wrong (fan, hard drive, etc.). What in the world could this be ?

I went to the Apple Store in Amsterdam. It has costed me THREE ⚠ hours at the Genius Bar. The Genius immediately acknowledged the problem. He says it is valid problem. So what he did, is calling to the Engineering team in America.

Then, I got told Apple knows about the problem and is investigating this issue. They do NOT know which component causes this issue. Therefore, no repair can be offered. I have asked for a manager because this MacBook was the result of a swap due to a faulty MacBook earlier. He pointed me to the fact the MacBook was bought at Apple’s Online Store and not the store in Amsterdam. Therefore, the product needs to be swapped by Apple Online.

The Genius called Apple Online. I have been sitting there for an hour. He came back, telling me Apple Online doesn’t want to swap or repair it. The statement is:

Apple is aware of this problem and our Engineering team is investigating this issue. Unfortunately, we can not do anything for you now.”

The Genius has told Apple Online that he wanted to swap it, but the system blocked it. Apple Online doesn’t want to swap and says Apple Store in Amsterdam should swap it.

I decided to call Apple. Dutch law says Apple is REQUIRED to swap the laptop or repair it in a reasonable amount of time. Since they gave no outsight to an end date, this even can last for years, Apple has broken the law. I wanted to dissolve the purchase agreement. Then I got told by Apple on the phone that Amsterdam and the callcenter employee both have escalated this issue. Within now and 2 working days I will get to know what they will do for me.

If they will not swap, I’ll take the legal actions I stated above. I have nothing to complain about the Geniusses. They have done everything they can. Both Geniusses told me they feel ashamed of the way that Apple has treated me and that they fully take the blame for my unsatisfied feelings.

Let’s see what the outcome will be. Apple is updating the case and has made a note that I as a customer am claiming my rights in The Netherlands and am not agreeing on waiting forever. If Apple is reading this message; I am a customer. I have customer rights. You are legally required to obey the law. I have the right to get a repair or a new machine in 'a reasonable time'. Saying you are 'investigating this issue' and can not give a timeframe, means you are being unlawful. I hope the escalation will result in a new MacBook. Or I will dissolve the agreement and have my money back. Then I'll buy the same MacBook again, but then at the Apple Store, so I don't have to go through this legal ****. I bet Steve would be very upset now.

Another moment: install the coolers control software, something like Macs Fan Control (it's free) and set the fans speed faster. My MBP didn't pop with it, cause it doesn't go to overheat. Pops only at cold start.

I will not install El Capitan because when I press at the back of the dispay, it is popping a lot also. I can reproduce the clicking my heating up my MacBook. You can just run the yes command sometimes after each other. Running this command:

yes | yes | yes | yes | yes | yes | yes | yes | yes | yes | yes | yes | yes

Hmm, maybe it's another problem... As I described, my secondhand MBP 15 Retina early 2013 start to pops when I install the new Sierra. And it pops goes ONLY from speakers, it's not a mechanical pops from the thermal expansion. When I put a cigarettes box to the left speaker I hear POP only from right.

I can confirm. The MacBook doesn't pop with the coolers on. But I heated the MacBook first and then cooled it wit your app, too. And then it DOES pop! This seems to be an issue with the housing of this model.

Sorry for the vertical video, but on my video you can hear the popping and see how I reproduce it.

Hello:

Some people think it's a software problem, which is not true. I send again a message that I sent a few days ago to this forum:

I have the MBP 15 with 256 GB and I have the same problem. The "pop" sound started after a month of use of the MBP, so I could not change it in the first 14 days. The sounds are random but very annoying because they occur several times in an hour. I have observed the following:

1. It's not about the speakers, so it's not a software problem.

2. The "pop" sound is heard on the left and center of the MBP. It could be the left hinge and is almost certainly due to the expansion-compression of materials by temperature changes.

3. Sometimes the "pop" sound can be played by moving the screen slightly after a working time, when the temperature change causes the problem. Sometimes it can also be reproduced by making light pressure on the outside of the screen, in the lower center, between the hinges.

4. Personally I consider that the problem is because the new design has not placed the two central screws between the hinges. This reduces the rigidity of the MBP and allows the components to have more space for movements caused by changes in temperature. My theory is corroborated by comparing with the 13 "MBP that has less between hinged space so it is more rigid, and therefore does not present this problem.

I have not taken my MBP to the Apple Store because I will surely get the same response as many of you. I'll wait for Apple to officially address this issue. It is also expected that with a time of use maybe the problem is not present due to the slight wear that may have the materials that cause the "pop" sound.

Agreed.

I exactly have the same thing. Pressing the touchpad causes the same sound. Could it be the 'brand new touchpad' causing this issue? Sounds reasonable. They have changed it on both MacBooks.

Indeed, as I stated above, this can be reproduced by influencing the temperature of the internal components. Poking the screen indeed causes this issue too. Ok, so maybe not the touchpad but indeed the hinges?

I am not sure. I agree it has some thing to do with the hinges. But it could also be because the speakers are near the hinges, which means the metal has less a less maximum weight to support. Just adding 2 screws, will not fix it. And where will you put these screws? Seems like the housing needs a bit of a redesign then.

At least report this issue to Apple. Waiting for normal 'wear and tear' is a ridiculous idea. The MacBook is not supposed making this sound anyway.

Hello:

First apologize for my English.

I already talked to Apple by chat and they told me that they still have not registered that problem. They asked to go to the physical store to check it out. I will not do it until there is an official pronouncement of apple, I do not want to leave it in their hands if they do not know the solution.

I have read that it has appeared in the MBP of 13 "but in very few occasions, nothing compared to the 15".

If I'm completely sure it's hardware. If the sound does not play at random, after a period of work, by pressing lightly on the back of the screen, 5 cm below the Apple logo, it plays. You can also reproduce by moving the plant slightly after a few minutes of work. I intuit that it is a problem of the new hinge system that extends throughout the MPP, since it is heard in the central part.

Hi All,

I agree with Hector, it is a hardware/mechanical issue with the laptop. Some people have reported the issue with the speaker popping noise, but I think in this forum thread, people are mostly discussing the mechanical popping.

Has anybody heard back from Apple yet?

Last time I heard back from Apple, through Engineer's at Apple. They deemed it as a cosmetic issue, so I have raised the issue to the UK Citizen Consumer Advisor, and they have got back to me to get in touch with the seller. I never bought Apple product from Apple directly. As their service is **** and buyer ends up paying a fortune for the product. So I get it from the reseller at discounted price.

Seller has got in touch with the Apple, and hopefully, I should be able to get it resolved.

Who bought it directly from the Apple in the UK, as per UK Citizen Consumer Law. They are entitled to repair, if that can't resolve the problem, I think they can ask for the refund as long as this is within the warranty period.

Refer to this page https://www.citizensadvice.org.uk. I encourage everyone who has faced this issue and unable to get the problem resolved by Apple should send a complaint about the problem to them.

I think we need to show the concerns as a consumer we are facing and by posting the issue and by growing the thread in this forum, we might be able to get some attention from the right person either from Apple or media or from the Consumer Advisors. Who can help us sort the problem?

I would encourage everyone who is facing this should help us grow by posting the issue and solution offered by Apple when contacted to Apple about the issue and dont forget to mention about the quality of the service offered by the Apple.

I have managed to replicate the pop twice by quickly changing desktop screens repeatedly over a period of around 30 seconds when it is cold. I have also started to notice a small knock or clunk when tipped left side down and when moved quickly in a sideways motion, it is almost definitely not the hinge. The movement knock is coming from the screen, when it is moved from side to side when closed i feel absolutely no play in between the screen and body but still hear the knock. I am taking it in again tomorrow, hopefully the sound can be replicated this time.

I have sent this video: How to reproduce popping sound MacBook 2016 - YouTube to Apple. At this video, you can see how to reproduce this issue and the trigger points that will also cause the popping sound.

What you can do is: send the command yes | yes | yes | yes | yes | yes | yes | yes to Terminal for 3 or 4 minutes until your MacBook heats up. Wait a few minutes and it will pop without me even touching it. Then, close Terminal and use Mac Fan Control to cool your MacBook down. It will also pop. Then, finally, when the MacBook is cold again, touch random places of the casing. You will be able to reproduce it.

I have sent Apple an e-mail that this product does not fulfill my expectations. According to Dutch law, Apple is required to repair it, or give me a new one. If they can not do so, I have the right to ask for a refund. Which would be fine. I would not buy it at Apple's site, but in a physical store, then.

I hope some of you can try do to the same thing as I did on the video. Then we know for sure it is a thermal problem.

Thanks.
