My iMac internal mic is not working.

The internal mic does not work on our iMac. Is this more likely to be a hardware problem?

iMac, OS X Mountain Lion (10.8)

Two things to look at; first Open System Report and see if your Mic is listed under the USB devices... if not try a


SMC RESET

  • Shut down the computer.
  • Unplug the computer's power cord and ALL peripherals.
  • Wait 15 seconds.
  • Attach the computers power cable.
  • Wait another 5 seconds and press the power button to turn on the computer.
  • It is the 5 second timing that initiates the reset.


and see if it has reappeared. If it's still not there then it may be a component failure.
