How to turn off popping sound on Mac

In this short article, we cover how you can make this adjustment to the Mac volume sound in macOS and Mac OS X settings. Yes, it turns out you can switch it off completely, which means you don't need to hear that little quack or popping sound again. 

With this little change, whenever you hit the F10, F11, or F12 keys to change volume, you’ll notice it’s not accompanied by a small quack sound. Always useful when in a co-working space or library,  or about to take a Skype or Slack channel call on your Mac. Here is how you make that change: 

How to mute the volume adjust noise 

  1. Go to System Preferences in the  Apple menu.You can also get to System Preferences through Siri, Spotlight Search or through Finder > Applications. It is one of the most commonly accessed areas of the settings within a macOS. 
  2. Within Systems Preferences go to the Sounds panel (visible with an audio/speaker symbol)
  3. Now uncheck the box next to where it says: “Play feedback when volume is changed” 
  4. And there you go. It really is that simple. Exit out of System Preferences. 

With this small change made, the next time you hit a shortcut key to change the audio volume on your Mac, it won’t make the pop or quack sound that you've been hearing this whole time. If you ever want to regain this sound, you can always go back within the Sounds panel of System Preferences and tick the same box you've just unticked. The change is always instant. 

Another audio feature that can be easily disabled within this area of your Mac is the startup sound. This can be quite loud, so if you are often in a co-working space or library when switching a Mac on, this is a good one to mute.
