I ca no longer use my video on Skype, or iChat, it says my camera is in use by another application. Although I can't think what it is nor how to find it. I've tried doing a reset of the SMC but the problem still persists. Can anyone please help?
Thanks
Welcome to Discussions, Tixie
If merely restarting your Mac does not correct the problem, try
all relevant suggestions from:
 
http://support.apple.com/kb/HT2090
If your iSight problem occurs in more than one app
and more than one user account, the reset suggested there often restores proper function of inbuilt iSight.
However, if after carefully following all the suggestions in the "How to Troubleshoot iSight" article, your built-in iSight still does not work, and if it does not show as a USB device in your Mac's
System Profiler, yours is most likely a hardware problem. In that case, contact Apple or an Apple-Authorized Service Provider for service.
