If the microphone on your MacBook is not working, there are several things you can try to troubleshoot the issue:
Check the microphone settings: Ensure that the microphone is not muted or turned off in the settings. Go to System Preferences > Sound > Input and check that the correct microphone is selected and the volume is turned up.
Check for external device interference: If you are using an external microphone or headset, unplug it and try using the built-in microphone. Sometimes external devices can interfere with the built-in microphone.
Restart your MacBook: Sometimes, simply restarting your MacBook can resolve the issue. This can reset any software or settings that may be causing the microphone to malfunction.
Update macOS and apps: Ensure that you have the latest version of macOS and any apps that use the microphone. You can do this by going to the App Store and checking for updates.
Reset PRAM/NVRAM: Resetting the PRAM/NVRAM may help resolve microphone issues. Shut down your MacBook, then hold down the Command + Option + P + R keys and turn it back on. Keep holding the keys until you hear the startup sound twice.
Reset SMC: Resetting the System Management Controller (SMC) can also help resolve microphone issues. Shut down your MacBook, then hold down the Shift + Control + Option keys and the Power button at the same time for a few seconds. Release all keys and turn on your MacBook.
Check for hardware issues: If none of these steps resolve the issue, it’s possible that there is a hardware issue with the microphone or the audio input port. Contact Apple Support or visit Esmond Service Centre for further assistance.
By following these steps, you should be able to troubleshoot microphone issues on your MacBook.
