My external iSight camera quite working after OS upgrade. It appears the Firewire port is dead. Camera doesn't turn on, no green light. The camera is not recognized by any software.

iSight, iOS 6.1.1

    Restart your Mac and troubleshoot using suggestions.


    Be sure to test more than one Apple app in more than one user account.  Do NOT use the "Guest" account for this test.  If you do not have more than one user account for the testing, create a new one now.  (A "Standard" account is all you need for testing.)


    If your trouble persists, when you post back here tell us:


       (1) what version of OS X you use.


            (You can find this with your Mac's  > About This Mac menu command.)


       (2) Whether the "upgrade" you mean was an OS X upgrade, an iOS upgrade, or both,


       (3) whether your external iSight works with Apple apps like Photo Booth, iMovie, etc.


            If not, confirm that the symptoms are EXACTLY the same in every user account.



    We will offer more specific suggestions based on the details you provide in your response.

    You have tried several good things.  With all you have done, and with your iSight not being recognized as a Firewire device in your Mac's System Information, I understand why you feel you have eliminated software as a possible cause of your trouble.  That leaves only hardware possibilities.


    Here are the hardware alternatives I can offer

    Consider any you have not tried in any order you like:


    (1) In addition to Apple's article, consider my expanded troubleshooting suggestions at


    Be certain you are NOT chaining your iSight when testing.


    Testing with a different Mac an connectors can help find whether the problem is in the iSight itself.


    (2) Reset Firewire ports using the info from this old archived Apple article:


    (3) If you iMac does not have a Firewire 400 port, test with more than one 6pin - 9pin connection cable or adapter.


    (4) If you have no local Apple Authorized service Provider who can service your iSight, other service options are here:


    (5) Replace your non-working Firewire iSight with a new USB cam with current warranty such as one listed here:
