When you’re using your iMac, you may find that your green indicator light for your iSight camera is often on, even when it appears that you don’t have any applications open. The green light is an indicator that the iSight camera is turned on, so if it’s on, you must have either Photo Booth, iMovie or iChat enabled.

Apple’s iMac, MacBook, MacBook Air, and MacBook Pro computers incorporate a camera at the top of the display. This device is called the iSight camera, which has a small, green indicator light to the right of it that turns on when the camera is activated.

So when you have your Mac webcam not working, make sure you’re not being denied access to the camera because some other app is using it at the moment: Launch Activity Monitor from Applications. Quit all other open apps or utilities that might be using the camera (e.g. Skype, FaceTime, and Photo Booth)

Control access to your camera on Mac

1. On your Mac, choose Apple menu > System Preferences, click Security & Privacy, then click Privacy. Open the Privacy pane for me.
2. Select Camera.
3. Select the checkbox next to an app to allow it to access your camera. Deselect the checkbox to turn off access for that app.

Can my Mac’s camera be hacked? The short answer is yes. It is possible for malware running on your Mac to turn on the iSight camera and record video or still images and audio from the microphone, and send it to a storage location on the internet. There have been other instances of malware that has this capability.

But, just like any other tech devices, webcams are prone to hacking, which can lead to a serious, unprecedented privacy breach. Think of a case where an authorized person accesses and illegally takes control of your webcam, without your knowledge. Such a person will effortlessly spy on you and the people around you.

Here’s the short answer: You should, when feasible, cover or disconnect your webcam when it’s not in use. Webcam hacks have happened many times before, to cameras that supposedly couldn’t be activated without an indicator light showing. The solution can be as simple as a little piece of tape.

Scott, however, said that a major clue is if the little LED light next to your camera is on, even when you’re not using it. ‘The most obvious indication that a webcam has been hacked is the activation of the indicator light,’ he said. ‘However, this signal can easily be disabled by even an unsophisticated attacker.

If you are unsure you can check if one is installed by going into Control Panel, open Hardware and Sound, then look in the Devices and Printers menu. You will see the camera, along with a camera icon, if there is indeed a camera installed. If you can see the camera lens then chances are good there’s a camera.

To open up your webcam or camera, select the Start button, and then select Camera in the list of apps. If you want to use the camera within other apps, select the Start button, select Settings > Privacy > Camera, and then turn on Let apps use my camera.
