Since I updated my mac to OS X 10.9.4 I've been unable to use my camera, say Facetime, Skype, Photo Booth and even the iMessage, Apple once uploaded a fix for OS X 10.8.5 but it doesn't work with this version. What can I do?
Ps. My MacBook Air is the one from late 2010 13 inch.
MacBook Air, OS X Mavericks (10.9.4), I've had my mac since since 2011.
