In other cases, the hacker has been able to remotely control the camera and use it to spy on the person using the computer.
How Can I Tell If My Mac Is Being Monitored?

You can do this by opening the Activity Monitor and looking for anything out of the ordinary, to make it easier you can follow the step-by-step using terminal and look for apps that not intentionally you use.
Another way to tell if your mac is being monitored is to check the Sharing preferences.

- Open System Preferences and click on Sharing.
- Look at the left section, a list of services that have sharing capability. Most of it is usually disabled, If you see anything suspiciously enabled or you don’t know what that’s used for, it may be an indication that someone has gained access to your mac, better to make it disabled by unchecking the checkbox.

What Can I Do To Protect My Mac From Being Hacked
If you are concerned about someone monitoring your mac, there are a few things you can do to protect yourself. The first is to install a VPN. This will encrypt your connection and prevent anyone from intercepting or monitoring your data.

Finally, you should keep your mac up to date with the latest security patches. This will help to prevent any vulnerabilities from being exploited by hackers.
Should I Cover My MacBook Camera
Most people don’t, and for good reason. Apple specifically says that you shouldn’t close your MacBook, MacBook Air, or MacBook Pro with a cover over the camera. Doing so could damage your display because the clearance between the display and keyboard is designed to very tight tolerances. Covering the built-in camera might also interfere with the ambient light sensor and prevent features like automatic brightness and True Tone from working.
That said, there are times when you might want to cover your MacBook camera. Maybe you’re in a sensitive work environment where you can’t risk someone spying on you through the webcam. Or maybe you just want an extra layer of security against potential hackers. If you do need to cover your camera, make sure to use a cover that is no thicker than an average piece of printer paper (0.1mm). And avoid using a camera cover that leaves adhesive residue. Finally, if you install a camera cover that is thicker than 0.1mm, remember to remove it before closing your computer. To understand more deeper, read our guideline about MacBook Camera Cover.
