vid = videoinput('macvideo', 1, 'YCbCr422_1280x720');
preview(vid);

Was the webcam object still in the workspace when you previewed this? That webcam object should be deleted, because the camera can be only be accessed by one object at a given point in time. Use
clear cam % where cam is the webcam object
