How to Fix Microphone Problems on macOS Mojave

Mac’s internal microphones are quite handy and more reliable than third-party external microphones. They can be used in daily applications like in Discord and Fortnite for communicating with gamers, as well as Skype for talking with business owners or distant relatives. So, when these microphones are not cooperating, we won’t be surprised if Mac users easily get frustrated, right?

Now, if you are looking for ways to fix a microphone that is not working on macOS Mojave or other operating systems, then you’ve come to the right place. We created this post to provide you with the possible solutions to resolve any microphone problems with macOS so you can continue your communications with your colleagues, friends, and even relatives.

Mic Not Working After Mojave Update

If you suspect that your microphone got damaged after the Mojave update, then here are some possible fixes:

Solution #1: Configure the Microphone Settings.

  1. Click the Apple button to open the Apple Menu.
  2. Go to System Preferences.
  3. Select Sound and double-click to open it.
  4. Navigate to the Input
  5. Select Internal Microphone if it’s not the default device for sound input.
  6. Try to speak into the microphone and see if the bars in the Input Level
  7. If the bars are rising as you speak, then the microphone is working just fine. Otherwise, there is a problem with your internal microphone. If the bars are not moving, adjust the Input Volume to the maximum level.
  8. Now, speak again in the microphone and observe if the bars are already moving in the Input Level.

Solution #2: Restart your Mac.

If your internal microphone is no longer responding or not working on your macOS Mojave, we suggest you reboot your computer. Allow it to start fresh and check if the microphone works. To restart, simply click the Apple button to open the Apple menu. After that, choose Restart.

Once your Mac has restarted, try using your microphone and see if it is already working. If not, try the next solution.

Solution #3: Reset the PRAM of your Mac.

The Perimeter Random Access Memory or PRAM is sometimes the reason why your microphone is not working. This component is responsible for many configurations and settings on your Mac, including the alarm clock settings, serial port definitions and configurations, mouse scaling, monitor depth, disk cache, and speaker volume.

As you can see, it’s a hardware thing. But resetting it sometimes fixes the problem. Here’s how to reset the PRAM of macOS Mojave:

  1. Switch off your machine.
  2. Now, switch it back on by pressing and holding the Power button and the Command + P + R+ Option
  3. Release them together once you hear the startup sound or before the gray screen appears, else it won’t work.
  4. Allow your Mac to normally reboot. You should have successfully reset your Mac’s PRAM.
  5. Lastly, reconfigure your microphone settings. To do that, refer to the first solution.
  6. Test the microphone.

Solution #4: Create a new user account.

If the first three solutions did not work, then the microphone issue might have something to do with your user account. And if that is the case, you might need to create a new user account on your macOS Mojave. Here’s how:

  1. Click the Apple button to open the Apple Menu.
  2. Select System Preferences -> Users and Groups.
  3. Log out of your current account and create a new one.
  4. Log in with it. Do not switch to another account as it will not work.

Still, if your microphone is not responding on macOS Mojave, the problem might be with your hardware. So, the best thing you can do is to seek Apple Support. Better yet, go to the Apple Store and speak with an Apple Genius. He or she can give you clear and concise solutions for your microphone problems.

If All Else Fails, Then

Did the Apple Genius suggest replacing your internal microphones? Well, it can be a costly and time-consuming process. And if you have an important call to take, you cannot afford to wait a few more days. So, your best temporary option is to use an external microphone.

Depending on the type of external microphone you currently have, it will connect to your Mac in various ways. Even so, all connections will use the same port: the USB port.

Among all types of external microphones, the easiest to connect to your Mac is a USB microphone. You just have to plug it directly into an open USB port and you’re done. This type of microphone already has a built-in pre-amplifier chip into its chassis, allowing it to support audio and output digital signals.

In Conclusion

Microphone problems on your macOS Mojave aren’t really that bad, unless the mic needs total replacement. With the solutions we provided above, you should be able to fix any microphone issues by yourself in no time.

Just to be sure that no other apps, files, or system errors can trigger a microphone problem on your Mac, we suggest you install Tweakbit Mac Repair. This tool will optimize and clean your Mac to ensure it performs efficiently and well.
