Q: Macbook air Mac OS X 10.7 camera not working

Hello,

I didn't notice untill recently that my camera isn't working anymore on any program which requires a webcam. It just says "no webcam available".

I've got my Macbook Air since September 2012 and the latest available update for my macbook (Mac OS X 10.7.5) is installed.

Does anyone know how to solve this?

Kind regards

Sanne
