So here's the story: my mother recently updated her 2007 MacBook to OS X 10.7 because she wanted iCloud to sync with her iPhone. However, upon updating, she found that her iSight camera will often stop working. I have attached a screenshot of what she sees when FaceTime starts while the camera is failing. She would restart her MacBook, and it would start to work again. Then after a few hours, and sometimes in a day or two it would fail again until she restarts. This is really problematic because when she receives FaceTime calls, she can't answer them without restarting sometimes. I've tried reinstalling the OS from the recovery partition, resetting the System Management Controller and also resetting the PRAM. None of those fixed the problem. Does anyone have an idea what to do? Anything is much appreciated! Thanks a ton!
