From today’s morning webcam of my macbook pro 2011 is not working. I had tried to fix this problem by reinstalling the webcam driver but not able to fix this problem. Every time I click on the webcam icon an error message displays, no webcam found after searching. My macbook is in warranty but right now I am on a tour and I don’t want to waste my time on it. So I want to ask this from you people, what I need to do?
