my camera doesn't work
My Webcam is not working for Photobooth, Facetime or my online language class that relies on a webcam. The light is green, so I know it is there, but Camera is not an option in my Finder.
Question marked as
This is a curious statement: "Camera is not an option in my Finder." (?)
You use the camera through the apps, not sure what you expect to see in Finder... maybe I am missing something.
From the >(option key) System Information>Hardware>Camera
You should see hardware info:
If no info here, then the sys is not recognizing the hardware—then it is a hardware problem for sure.
The "light is green" mentioned above seems to indicate is both recognized an turned on.
Otherwise try resetting NVRAM/PRAM http://support.apple.com/kb/ht1379
