Microphone Not Working: Here’s How to Fix It How to turn on microphone on mac To check the settings when your mic input not working Mac “System Preferences” menu is your best option. Your Mac’s mic may not have been set up properly, or its settings could have been changed for some reason. Using a monitor with a mic included? Many modern monitors have mics, and it’s possible your app or computer are defaulting to that mic rather than your Mac’s internal microphone.

Yes, Honza1, this Macbook Pro has been rebooted several times since the Big Sur upgrades several weeks ago. I will use Google to learn how to reset nvram and smc (and to find out what those are! ?)
