How to Check a MacBook Camera

Click the 'Photobooth' icon on your MacBook's dock or from the 'Applications' folder. The webcam should turn on, presenting an image from the camera on the screen.
Check to see if the computer recognizes the camera if the image from the webcam does not appear. Click 'Finder' on the dock and click 'Utilities.'
Click the 'System Profiler' icon. Click the 'USB' entry under the 'Hardware' section. The 'Built-in iSight' entry should appear under the 'USB High-Speed Bus.'
