Camera not working after yosemite upgrade

Reset SMC. http://support.apple.com/kb/HT3964

Choose the method for:

"Resetting SMC on portables with a battery you should not remove on your own".

I tried this (MacBook Pro, 2011), although with the SMC reset, there was no real way of checking whether anything had happened...I held down the buttons as instructed for 3-4 seconds and hoped for the best. Did it twice because the first time it didn't work. Neither did it work the second time.

The camera works fine with Skype. With FT, the message is "there is no connected camera" and there is no way (like, perhaps, under the VIDEO tab??? There's only MICROPHONE information there. Huh?) to connect a camera to FT. Really odd. Nothing happens when I click "preferences" either.

Any ideas?

I have closed and reopened FT.

I have rebooted after closing all applications.

I have hard rebooted (using power button) after closing all applications.

I have done the SMC reset.

I am close to throwing the computer against the opposite wall, but I suspect that may be even less useful than the preceding four efforts.

Any suggestions (particularly with sympathy) welcomed.

My camera was not working either after upgrading to Yosemite. But I've reset the SMC and it worked for me. Here are the steps I've followed (since all the apple support pages linked returned a 404 error code, I had to find them elsewhere) on a mid-2012 Macbook Air:

• Turn off the mac (by holding the power button);
• Plug in the magsafe adapter and make sure it is charging;
• Hold these four keys and release all of them at the same time: Left Shift, Control, Option (Alt) and the Power Button;

If your battery is not completely charged, it should be easy to verify that you did it properly since the orange led in the magsafe adapter should blink green and then go back to orange.

Nothing help me. I tried everything.

Now I even restored to Mavericks and still no camera.

I think Yosemite has killed the iSight camera.

HELP

If resetting the SMC didn't work, I'd try to contact Apple Support, since I don't remember finding any other solutions on the web.

No idea how and why - today it is working. very strange

Just upgraded today, more is the pity. Camera now is not detected. Have 2012 MacBook Air so cant remove battery power. Tried SMC and all other suggestions. I see izibizi reverted to Mavericks. Did the camera work in Mavericks or Yosemite when it did work. It has to be something to do with the upgrade and I trust Apple will provide an update to solve the problem. very soon. Any other ideas???

WHen I reverted to Mavericks it still didn't work.

at this poin i was sure it is a hardware issue So I decided to upgrade again to Yosemite.

After the upgrade it still didn't work.

the next day as I was about to take it to apple I checked again and it was working.

Well well. What is happening! Woke up this morning and switched on and there was my camera working. Didn't do a thing - same as izibizi. Some sort of delayed reaction in Yosemite upgrade?

Thanks for sharing this, I started to wonder if I am well...

One more anomaly. Turned on today and went to Facetime. "Camera not connected" Came back 1 hour later and Camera is working! Really cant understand whats going on.

Must be a problem with your internet service, connection, configuration, local network, or your Mac hardware or software.

Start with FaceTime for Mac: Troubleshooting FaceTime.

Sorry, nothing to do with Facetime. It is to do with the Camera itself and the detection of the hardware by the system. This morning, I checked through "System Information"/Camera and the camera is detected. Later, I go on to Skype, Facetime or Photo Booth and Camera is not found. Check through System Info again and No Camera is found. So, I leave it for 1 hour and everything is working OK again. It is so intermittent and unpredictable. I did not have any problems pre Yosemite.

You're right, Jim. Could be anything. But totally stable 3 days ago, pre Yosemite.
