I have a late 2008 aluminum Macbook running OSX 19.9.2. I just tried to make a FaceTime call, but the Facetime screen says, "No Camera Available. To use FaceTime, connect a camera". It worked as recently as last week and I haven't updated the software since it last worked. I googled the issue a bit and came across a potential solution by typing in 'sudo killall VDCAssistant' into Terminal. But, when I do that, Terminal returns, 'No matching processes were found'. Does that mean that I'm probably stuck with a hardware issue (bad camera) or are there some other things I can try? I have restarted and that didn't help.
