First I thought it was iglasses which I removed. I then unplugged my secondary Logitech cam; but still I can't get any image from the Built in iSight Camera after my Lion install.


It shows up as a USB peripheral in the mac System Profiler. What gives?



Aluminum iMac 20 inch, Mac OS X (10.6.5), 4 gigs RAM 2.66 Ghz

There is a simple fix. Shut down the mac; unplug for 15 seconds. Plug in; wait 5 seconds. Then press the power button once. That should reset the SMU and fix the isight. It did for me.

    I'm having EXACTLY the same issue! I spoke to apple and they told me it was a hardware issue despite the fact it was working with Snow Leopard?!?!

    Thanks to "raspberryaddiction" I followed your instructions to the letter and it worked - Thank You - saved me a lot of hassel.

    I hope that works! I tried this with the last Snow Leopard version (was having the same problem) and it only worked immediately after restart, and then after some unknown amount of time, iSight would quit working again. In order to use Skype, gChat, or any other programs, I would always have to restart my computer to get it to recognize again. So frustrating! This was never a problem until the last version of Snow Leopard, and now Lion. Argh! There does not seem to be a permanent fix.

    I lost the camera under Movie '08, but the suggested fix has not worked for me.  I have physically moved the machine twice in the last few days (for unrelated reasons), so it has been shut down and unplugged for more than the suggested intervals, but no success.


    It still works under FaceTime and Photo Booth, so the problem is not with the camera itself.


    Anyone else have luck with another solution?

    My computer was actually recognizing my iSight. Is yours? To tell, do this:



    Instead of powering down and unplugging, I turned my computer off, and actually took out the battery for about 30 secondsy. Then put the battery back in and in order to turn back on, press the power button for about 15 seconds. It will make a kind of awful beep noise before the normal Mac noise. So far, it seems to have fixed it, but we'll see...

    Hi there mollyd8, yes, the computer still recognizes the USB iSight camera according to the system report. But the camera still doesn't work, not under any application or any userid. Also not after the SMU reset thing. I must say, this is something I had not expected from Apple..... The only comfort is that many people are experiencing this problem.

  • douwevt Level 1 Level 1

    Solved it! I unplugged my scanner, and suddenly, the iSight camera was recognized by all aplications.

  • mollyd8 Level 1 Level 1

    I don't know what the overall problem is, but mine seems to work if I bite the bullet and shut down every day instead of being lazy and just closing the laptop and putting it to sleep. Every time it goes to sleep, suddenly migh iSight is gone. So shut-down it is. Annoying but it works. At least you've found a solution! Sigh...

    My iSight works without sound in FaceTime. iSight works normally in Google Video Chat. Lion has problem with iSight and FaceTime? Under FaceTime/Video drop down menu, the Microphone input list doesn't see iSight.

    Hi, i read this very useful post to undestand why my iSight camera won't work under Quicktime video recorder, on Mac OS X Lion 10.7.2. I was sure it worked in the past, and for example Photo Boot works, Skype works but not Quicktime. I tried the reset pause, and anything happens. Solution for me was the idea of disconnect some USB peripherical. It was my external audio card for me, a Focusrite Scarlett 8i6 audiocard. It starts to work immediately. If i reconnect the audio card after the working window in Quicktime, it seem to continue to work in a perfect way, but if i close and reopen Quicktime iSight still blocked. Very strange, anyway i just can make it start when i need. I hope this will be useful to others.
