My iSight camera is no longer working on my Macbook Pro Retina. I'm trying to reset SMC using the directions Apple provided, but I can't tell if it's working. I'm not seeing the light flash on my MagSafe, nor is the system doing anything that tells me it was successful. Any idea?


This is what I'm doing:


  1. Shut down the computer.
  2. Plug in the MagSafe power adapter to a power source, connecting it to the Mac if its not already connected.
  3. On the built-in keyboard, press the (left side) Shift-Control-Option keys and the power button at the same time.
  4. Release all the keys and the power button at the same time.
  5. Press the power button to turn on the computer. 
    : The LED on the MagSafe power adapter may change states or temporarily turn off when you reset the SMC.
MacBook Pro with Retina display, OS X Mountain Lion

    Sometimes when doing a SMC there is no indication of anything, at the  bottom of the the instruction page you will see that the power adapter may change states.


    You can click on the Apple logo holding the OPTION key, then click on system info, in the left side bar click USB.

    The pane that comes up should be "USB Device Tree" look and see if it shows Facetime HD/iSight camera (built in) is recognized, there will be info as to model, vendor, etc...


    If not recognized, you may want to take it in to Apple for a diagnosis
