How to Shut Off the Camera on a Macbook
Every Macbook, a laptop made by Apple, comes with an iSight camera above the display, which you use to shoot pictures and videos. There is no physical switch on the laptop to turn the camera on and off. The camera activates automatically when you run an application that uses it, such as QuickTime or Photo Booth, which are free applications that Apple installs on every Macbook. To shut off the camera, you simply quit the application that is using it.
Click on the QuickTime icon in the Dock of your Macbook to launch the video application.
Click "File" from the QuickTime menu, then click "New Movie Recording." The iSight camera's light glows, indicating that it is on.
Click the red button to record a video.
Click the black button to stop recording the video. The iSight camera's light turns off, indicating that the camera is shut off.
Click on the Photo Booth icon in the Dock of your Macbook to start the Photo Booth application. The iSight camera's light glows, showing that it is on.
Click on the picture icon (a square) to set the iSight camera to shoot a single picture. Click the 4-up icon (four small squares) to set the camera to shoot four pictures in a row. Click the film frame icon to set the camera to shoot video.
Click the camera icon to shoot a picture or record a video. Photo Booth starts a countdown, then shoots your picture or records a video. Click the black button to stop recording a video. Pictures and videos appear as thumbnails in a row along the bottom of the Photo Booth window.
Click "Photo Booth" from the Photo Booth menu, then click "Quit Photo Booth." The light next to the iSight camera turns off, indicating that the camera is shut off.
