I have not been able to get quick time player to play videos I have recorded on my camera. If I click on a video file nothing happens . If I right click on the file it show QT as default but clicking on it does nothing either. QT also doex not show up in the bar next to the apple icon. VLC is the only for me to play these files. This came preinstalled with the macbool when I bought it last year and has never worked for me. What gives?
