Have you ever found yourself in a situation where your built-in MacBook microphone refuses to work? This can be frustrating, especially if you're trying to record a video call or make a voice recording. Fortunately, there are a few simple steps you can take to troubleshoot and fix the issue.

Step 1: Check Your Audio Input Settings

To start troubleshooting, open System Preferences on your Mac and click on 'Sound.' In the Sound preferences panel, select the 'Input' tab. Look for the microphone icon in the list of available sound input devices. If you don't see it listed, try restarting your Mac or checking to make sure that the microphone is not disabled.

Step 2: Adjust Your Input Volume

Even if your microphone is working properly, you may need to adjust the input volume to compensate for the sound source being too loud or quiet. To do this, open System Preferences and click on 'Sound,' then select the 'Input' tab. Drag the 'Input volume' slider all the way to the left to disable the microphone. You can test whether the microphone has been disabled by talking into it - you should no longer see the mic indicator moving.

Step 3: Check Your Energy Saver Settings

In some cases, your Mac's energy saver settings may be preventing the microphone from working properly. To check this, open System Preferences and click on 'Energy Saver.' Drag the 'Display sleep' slider all the way across to 'never' (on the right-hand side). This will prevent your screen from going to sleep while you're using your Mac.

Step 4: Restart Your Mac

If none of the above steps work, try restarting your Mac. Sometimes, a simple reboot can resolve issues with your microphone not working properly.

By following these simple steps, you should be able to troubleshoot and fix any issues with your built-in MacBook microphone not working. Remember to always check your audio input settings and adjust your input volume as needed to ensure that your microphone is working correctly.
