Strange pop sound sometimes

I have a strang issue, sometimes not often I can hear a pop from my new mbp.

Yesterday it did happen two times in a raw, first pop then 30 sec later pop again.

I can't reproduce it but it sounds exactly like in this video:


Is it a electronic discharge? Or is it from the speakers?

Is not a "metallic" sound anyway.

Here is an other video of the issue:

As the system is so new I would bring it into an Apple Store to have them check it out.

One thing you want here is documented proof you noted the problem so if in the future you do find it was something that needed attention you have hard evidence you encountered the problem which it was still under warranty.

I understand, also I have some kind of electric sound almost as it loads up electric when I boot the computer.

When I do attache the charger it sounds like this:

6-8 in the video after the normal charger sound you can hear it.


It's clearly something wrong with the machine, I'll try to replace it today as I had this for 6 days, its my 3rd MacBook Pro 2016 - I'm thinking of swapping it for a 2015 15" it's 4 core CPU and 16GB of ram on the 2015 modell that they have in the store so it's better then this one and I'm so tired of replacing the machine.

3 Times come on APPLE! That's not OK.


Please do us all a large favor here!

Write an email to Tim Cook (tcook@apple.com). List the system serial numbers and the defect for your other two systems plus this one.

Make it short and to the point of the quality defects and your disappointment. Unless he hears it with proof he's just like our new Prez are in denial of the facts!


Well, it's in with a repair guy and they can hear the noise but they don't know what's wrong with it.


On anything I buy, if I have problems with it during the first year I take out the extended warranty. You can take out Apple Care to extend your warranty another two years as long as it is still within that first year.


I think I would demand a replacement system and make sure before I walked out of the store it was good.
