I was on tinychat yesterday and out of no where my webcam (isight) stopped working. When I try to open photobooth this comes up: I have reset the SMC & PRAM, but that didn't work. Then I read another thread saying to start in safe mode but every time I try to the little loading gear just continues to keep "loading". Basically just keeps spinning never loading the log in screen. This is an older MacBook from 2006 and my friend gave it to me because my old computer died. Also the green light doesn't come on at all. Help me please?!
