Fix the no camera found error in OS X 10.7 or 10.8

๐Ÿ•’  Posted

I restored my new MacBook Air from a Time Machine backup from my MacBook Pro and I have been running into issues as of late, mainly to do with the iSight camera. What happens is, when I go to use an application that uses my camera, I get an error message saying my camera is disconnected.

Disconnected? Pleaseโ€ฆ I was using it a half hour ago. So I began to Google questions looking for answers. I found all sorts of people saying to reset my SMC but to no avail. After about 15 minutes of scouring the Apple forums, I stumbled upon a gem that finally fixes my issue:

killall VDCAssistant

This solution however, does not expose the root of the problem. It seems to happen whenever I put my MacBook to sleep. It doesnโ€™t happen often enough to warrant replacing the computer, however it is rather annoying.

Readers, let me know if you find any other solutions which are permanent.

I want to hear from you, dear reader ๐Ÿ˜„
