If your iMac microphone is not working, it can be frustrating, especially if you use it for video conferencing or voice recording. However, there are a few troubleshooting steps you can take to determine the cause of the issue and potentially fix it. Here are some steps you can follow:
Check the microphone settings: First, check that the microphone is enabled in your system preferences. Go to the Apple menu, then System Preferences, and click on Sound. Under the Input tab, make sure that the correct microphone is selected and that the volume is turned up.
Test with another app: If your microphone is not working with a particular app, such as Skype or Zoom, try testing it with another app, such as Voice Memos or QuickTime Player. This will help you determine if the issue is with the app or the microphone.
Restart the computer: Sometimes, simply restarting the computer can fix minor issues with the microphone.
Check for software updates: Make sure your iMac is up to date with the latest software updates. Open the App Store and click on Updates to check for any available updates.
Check the connection: If you’re using an external microphone, check the connection to make sure it’s secure. If it’s a USB microphone, try using a different USB port.
Reset the PRAM/NVRAM: Resetting the PRAM/NVRAM can sometimes fix issues with the microphone. To do this, turn off your iMac, then turn it back on and immediately press and hold the Command + Option + P + R keys. Hold the keys down until you hear the startup sound twice, then release them.
Reset the SMC: If none of the above steps work, try resetting the System Management Controller (SMC). This can help fix hardware-related issues. To do this, shut down your iMac, then hold down the Shift + Control + Option keys and press the power button. Release all keys and turn the iMac back on.
If none of these steps work, it’s possible that there’s a hardware issue with the microphone. In this case, you may need to take your iMac to an authorized repair center or Esmond Service Centre for diagnosis and repair.
