Microphone not working on Mac

If you are wondering where is the microphone located on your MacBook? This depends on the model of your MacBook.

The newer MacBook Pro (2021) models come with 3 microphones in the left corner of the Mac, while the MacBook Pro (2017) versions had a single microphone near the ESC key.

When the microphone isn’t working on your MacBook, the problem can be due to various reasons, from temporary software glitches to microphone not set up properly and other reasons.

Usually, when you try to use an external microphone on your MacBook or Mac Mini, the problem is that the microphone is not recognized by your computer.

1. Configure the microphone settings

A common reason for the microphone not working on MacBook, Mac Mini or iMac is that the microphone is not set up properly or the input volume is kept at a low level.

Click on Apple logo in the top menu bar and select system settings in the drop down menu.

Open System Preferences on Mac

On the System Settings screen, click sound Tab.

After that, speak into the microphone and you should be able to see the level bars fill the entire selection.

2. Make sure the external microphone is listed as a sound input device

If you’re using an external microphone for Skype, Zoom, or Microsoft Teams calls, make sure your Mac recognizes the external microphone.

Go to system settings > sound > Make sure that External microphone is available in the “Choose a device for sound input” section.

If it’s not recognized, you may need one TRS to TRRS adapter to make the external microphone work on your Mac.

Click on Apple logo in the top menu bar and select Start anew option in the drop down menu.

Reboot Mac

After the Mac restarts, verify that the Photo Stream album now appears on your device, showing the most recently uploaded photos.

4. Allow apps to access the microphone

If the microphone on your Mac isn’t working while you’re using third-party apps (Skype, Microsoft Teams, or Zoom), the problem is usually because the app isn’t allowed to access the microphone on your computer.

Go to system settings > security > select microphone in the left pane. In the right pane, make sure that the Third Party App can access the microphone.

After that, you should be able to use the microphone on your Mac.
