Best.

None of the suggested steps work for me.

I've now tried to reset the SMC two times on my late-2012 MBP Retina, but this hasn't fixed anything.

There's clearly a problem here. I'm hopeful that a patch will fix it, but annoyingly, my MBP turns 1 year old in 2 weeks, so I am out of time to wait for one.

Video chatting is the primary means by which I communicate with the rest of my company; I never imagined a problem like this would be such a deal breaker.

Today, the day that I am writing this, I just got my Mid-2010 MacBook Pro back from an Apple off-site repair facility for Kernel Panicking. In order to fix the issue, they had to replace the entire logic board. When I was reinstalling my applications, I ran into an issue when setting up Skype as it couldn't find the iSight camera. I then got similar error messages when I opened up PhotoBooth and Facetime. The weird part was that in System Information, while there was no camera detected under the Camera header, the iSight was being picked up under the USB header. After talking to Apple Support over the online chat system this was the solution that worked for me (same as dominic23 suggested): Resetting the SMC.*

1) Make sure your Mac is being charged and that your MagSafe adapter is connected.

2) On the left side of your keyboard, press (NO NEED TO HOLD. JUST PRESS) Shift-Control-Option and the Power Button at the same time.

3) The computer will immediately shut off. (For good measure, I waited about 15 secs for what appeared to be a hard shutdown.) Then press the power button to turn your computer back on.

When the computer turned, I went back to System Information to find that a camera was now detected under the Camera header and that all the apps were now able to detect a camera as well.

*When I talked to Apple Care, the representative seemed quite confident that the fact that the iSight was visible under the USB header in System Information meant that Resetting the SMC would do the job. So check the Camera and USB headers to see what your situation is like.

Hope this helped someone!

Worked for me. TY!

Hello, thanks for the explanation. What if I can not see the camera in USB. I did the SMC reset but nothing happened. Please help, thank you!

I'm not sure about that one. Might be a hardware issue and in that case bring it into your local Apple Store and they can tell you what's wrong and what you should do if there is an actual hardware issue.

Shift-Control-Option and the Power Button helped!My camera was under USB header but wasn't under camera now it works. Thanks.

NguyenJulian This did it! My camera is back. Amazing what a fast google search can do!

I didn't even detect a camera in my USB header, and yet resetting SMC worked for me. Thanks!!

I'm having the same issue yet the reset isn't doing anything. Is it going to cost me to take it to the store and have them try? I am out of warranty...
