MacBook Microphone Not Working: How to Fix

MacBook users sometimes experience situations where the microphone doesn't work at all or in certain applications. In this article, we will look at the main reasons why this can happen. We will also offer a step-by-step guide to help to fix the MacBook microphone.

Why is my MacBook microphone not working

Not working MacBook microphone problems can occur due to restricted access in privacy settings, as well as a result of damage to the device or its wiring after a fall and other situations. Often, performance is affected by an outdated operating system and software conflicts.

If you use an external microphone, the contacts may become loose over time, causing the malfunction of your device. It is not uncommon for the microphone to stop working due to a malware infection.

5 tips how to fix MacBook microphone

It's easy to check the microphone and make it work again using our guide. A software problem can always be solved by yourself. In case of physical damage to the device, repair or replacement will be required.

1. Checking the microphone

The first thing to do is to check the general microphone settings:

• click the Apple icon in the top left corner of the screen;
• open "System Preferences" and select "Sound";
• tap on the "Enter";
• If the microphone is not selected by default, check the box next to it;
• adjust the volume using the slider bar.

To check the microphone, watch the indicator light - it should respond to external sounds.

2. Input settings

Your MacBook has a built-in microphone, but you can connect external microphones. Check which one your device is using. Go to the Sound tab in System Preferences and under Input, see which device is activated.

3. Voice recording

If the microphone works but you cannot record voice, check if this function is enabled:

• open "System Settings" and go to the "Keyboard" section;
• go all the way down to Dictation.
• check the correct language and microphone selection.

4. Application Authorization

If the Mac microphone generally works but not in all applications, the problem may be in the authorization. You can check this as follows:

• click on the Apple logo and select "System Settings";
• open the Privacy and Security tab;
• view the applications that are allowed to use the microphone.

To enable authorization, move the slider to the right so that the gray switch turns green.

5. Reset PRAM

For MacBooks with an Apple Silicon processor, this step is not necessary. For Intel-based computers, resetting the PRAM may help restore functionality:

• turn off the laptop, turn it on immediately and press Command+Option+P+R;
• keep the buttons pressed for 20 sec;
• release the keys and wait for your MacBook to start;
• check the microphone function.

You can also use the CleanMyMac X application. It removes unnecessary files, application remnants, and checks for malware. You can safely get rid of different files and, in case of problems, then you can restore them by creating a backup.

Mac microphone not working with Zoom, Google Meets and other apps

If the microphone doesn't work in this kind of application, most likely the reason is related to accessibility. Sometimes problems occur due to incorrect sound settings, an outdated OS version or a temporary software glitch.

Zoom

Make sure that Zoom has permission to use the microphone. Go to "System Settings", then open the "Security and Privacy" tab and click on "Privacy".

Opposite "Microphone", see if it is enabled for Zoom. If multiple microphones are connected, open Zoom and go to "Settings", select "Sound" and make sure that the correct device is selected.

Sometimes the MacBook microphone not working in zoom may be temporary. Try closing the application, restarting your computer and reopening Zoom.

Google Meets

Using the method above, check that Google Meet has permission to use the microphone. With an active session in the app, tap the gear icon in the bottom right corner of the screen and select Settings. Make sure the correct microphone is selected.

Check if the unit works in other applications or recorders. If it does not work at all, repair or replacement is probably needed.
