FaceTime camera isn't working with yosemite 10.10 (macbook air)

I had the same issue I gave Apple support a call and they told me:

1. Close all running apps

2. Shutdown your mac

3. Turn on your Mac, press and hold the following for around 4 - 5 seconds ctrl, cmd, P and R wait for the start up tune to play twice.

After doing that it worked for me.

Thanks Michael!

Macbook air mid2013 didn't work for me on Yosemite 10.0.2

Thanks so much!

Your hints were absolutely useful. It works at the first time.

Now I have my camera back again.

Greetings from Spain.

Try signing out of iMessage and FaceTime and then signing in again. That solution worked for me.

After spending a whole Saturday troubleshooting this dog, I finally (and accidentally) fixed it for my MBP Retina with Yosemite 10.10.3. Noted, I tried all sorts of common recommendations - reset SMC, sudo killall VDCAssistant, etc...

Here is the fix - I completely drained its battery last night, and today when I plugged it on AC, the camera was working with all apps - facetime, skype, photo booth... Voilá!!!

Good luck to all!

You are my HERO!!! Worked like a charm! (And sharpened both cameras, too!!!)

I love this forum!
