So I'm trying to help someone setup iChat on their MacBook for video-to-video chat, and iChat is now setup, but when we go to iChat -> Prefs -> audio/video and it says:

There is no camera attached to this computer.

But it's a new MacBook (he's had it for a few months), so it obviously has a camera.

Any idea what I need to do to get this MacBook to reconize it's camera?


I went to the system profiler, and the iSight is not listed in this macbook, so I tried to reset the SMC for a battery you should not remove on your own, but this did not resolve the issue.

Take a look in About this Mac => More Info => USB and see if the camera is showing up there (it should appear as "Built-in iSight").

If that works then make sure you're not running any other apps which might be hogging the camera, e.g. Skype, Photo Booth, etc.

for an app to hog the camera, wouldn't the green light have to be on? – erikvold Jul 22 '10 at 18:52
@Erik: good point – Paul R Jul 22 '10 at 21:37

I've had that a couple of times on my MacBook Pro.

Simply follow the process described here to reset the System Management Controller.

I followed the instructions to reset the SMC (this is a new macbook that should not have the user remove the battery, so I tried the shift+ctrl+option+power btn method), but that did not help resolve the issue. – erikvold Jul 22 '10 at 22:15

It sounds like there's a camera or a USB issue. If another application was using it (I just tested mine by having Skype grab it), the Audio/Video tab would say "Another application is using your camera" and the camera LED would be lit. But the message you got suggests you're looking for something at a lower level than another app.

Here's Apple's guide to troubleshooting the iSight camera.

so I just tried those intructions and they did not resolve the issue. – erikvold Jul 22 '10 at 22:14
