Previously working webcam in Yahoo Messenger has decided to balk - does not display to me and only very faintly to the other party. Any ideas, anybody?? Thanks heaps
Well, have you tried restarting? Maybe create a new user account in System Preferences and see if the problem continues there. That'll help determine whether it's a problem with something in your Home folder or not. 🙂
If nothing else works, reset the SMC "System Management Controller". However, if this issue is only occurring in one program, but the iSight works in others - I'd reinstall the application causing the problem. It your iSight is failing in all programs, try this: http://docs.info.apple.com/article.html?artnum=303319
I did this for the dreaded iSight cam "green screen issue" and it worked like a charm.
