My in-built camera MacBook Air OS X 10.9.5 does not work
The in-built camera of my MacBook Air OS X 10.9.5 (13F1507) stopped working after after I installed a Bitdefender Virus Scanner, and since then I have not been able to use it. I keep getting messages that there is no camera installed. I have even bought a web cam from apple store to replace it but could not get it to work either.
MacBook Air, OS X Mavericks (10.9.5), (13F1507)
