Macbook Pro Issue - High Pitched Keyboard Clicking Sound

Postby Donnieclark » Sat Dec 09, 2017 1:27 am


Within a few hours of using my Late 2016 MacBook Pro 15” with Touch Bar, I noticed some of my keys made a very high pitched click on-key-up (when I lifted my finger from the pressed down key). The affected keys: Caps Lock, left Option, and very occasionally: Delete, ‘H’, and ‘C’.

Caps lock is by far the most reproducible for me. Whenever the key stops making the high pitched click, I can always get it to start again by making a long key press with a little bit of pressure. I can only reproduce the high pitched click on the left Option key on about 25% of presses, and I’ve only noticed it on the Delete, ‘H’, and ‘C’ keys a couple of times .

I’ve recorded a video of the issue occurring for my Caps Lock key. I press the shift key 4 times to give a baseline sound for what the key should sound like, and then the Caps Lock key four times to demonstrate the issue. I did the same thing again, but just recorded the audio (the sound quality is a little higher than the video).

It’s important to note that I have only been able to reproduce the issue when the computer is warm.

Does anyone else has same issue?

How can I fix it?

Please help.

I didn't find the right solution from the Internet.
