Apple is always working on improving your security, and each macOS update brings new privacy features. In particular, macOS Catalina offers better control of your data. It requires apps to get your approval before accessing the camera and microphone on your Mac. Every time you open the application for the first time, you’ll need to permit it to use your computer’s camera.

Below we’ll show you how to give camera access for any installed app. Also, you’ll learn how to limit access for programs you suspect might be recording videos without your knowledge. Let’s dive in!

Securing your camera and microphone

That’s why when you open the program that wants to access your hardware, you’ll receive a pop-up. To give access, you just have to click OK. If this is a reliable app from a legitimate developer, you’ll need to confirm once and never think about it again.

If you clicked “Don’t Allow,” you could easily change that later on your Mac. You can check what apps are allowed to use your camera and allow or block access at any time. And here’s how to do that.

How to manage your camera permissions
