Privacy fears have more people than ever wanting to disable the camera on a Mac. Almost every Mac model has a built-in camera, which is connected to the mic, giving you audio and video whenever needed for FaceTime, Skype, or other calls using your Mac.

However, for Mac cameras can also be used to snoop on people with illegal software. Such as spyware, or even key-logger viruses. Cameras can be used to bribe and blackmail people, and make everyone feel a little uneasy using our Mac’s knowing someone else could be watching.

So to prevent this, you need to know how to disable the Mac camera. At the same time, you should also know how to enable it when needed again. In this article, we have a few solutions for both and cover some useful troubleshooting topics around this.

How to disable the webcam on a Mac?

Firstly, let’s start with a simple non-technical solution that anyone can do. Cover it using tape.

Security and intelligence chiefs and even Facebook CEO, Mark Zuckerberg, are known for covering built-in cameras with thick masking tape, or scotch tape. You can even use the sticky part of a Post It note. Don't use clear tape, that won’t work.

Using tape is simple, effective and cheap. It could, however, leave marks or scratches on your Mac, or potentially damage the lens, so it maybe isn't a long-term solution. Let’s take a look at other options:

1. Go to Settings; to disable audio and visual inputs, you need to open System Preferences (either via Siri, Spotlight, or the top-toolbar Apple menu icon.
2. Open Sound.
3. Click on Internal Microphone.
4. Now switch the audio input slider down to zero, thereby preventing any sound inputs from getting in.

Unfortunately, this isn’t going to prevent the camera from being accessed. There are viruses, such as OSX/FruitFly, OSX/Crisis, OSX/Mokes, and others, that are known for being able to remotely take control and record camera activity.

So you could either turn the audio down and tape it up, or there is another way to take control of the camera and avoid the risk of cybercriminals getting the benefit of these inputs.

How can they spy on you? A high school story.

In 2010, a High School in Pennsylvania issued a MacBook to each of its 2,306 students, then remotely activated the webcams to spy on the students at home. It didn’t take long for this to be discovered. Parents were outraged, of course. This massive violation of privacy and trust eventually ended up in court, with the school district eventually settling the case for $610,000 with parents and students.

How to disable the Mac camera within popular web browsers

macOS Safari, the built-in Mac web browser, has advanced security and privacy settings that make this easier. To access these, open Safari, and now click on Safari Menu > Preferences.

Within Safari settings, you can click on Deny to switch off the camera and audio inputs. Of course, with all of these changes, if you want to use it again, you will need to reverse these steps.

Other browsers, including Firefox, have equally robust and user-friendly security settings. You can easily switch off audio and video access for every web browser you use, making it that much more difficult for malicious software to hijack access and keep an unwanted watchful eye.

We hope the tips above about how to disable the camera were useful. But what about reconnecting it, when it is needed?

Simply go back to the settings within whichever web browser you disabled it, or back to System Preferences, and if tape was used, take it carefully off the camera.

What if, you can’t reconnect with the camera?

Start with deleting system junk.

Over time, a Mac can get full of everything from out-of-date files, duplicate images and videos, games and apps you don't need or use anymore. In particular, old cache files can interfere with the camera.

Use CleanMyMac X, a powerful Mac performance improvement app, to clear hard-to-find system junk, clutter and caches, to get your Mac camera working good as new again. Here is how you do that:

1. Download CleanMyMac X (download a free version here).
2. Use the Smart Scan to quickly and easily identify system junk.
3. It will also spot any third-party apps that could be interfering with the camera; these can be removed via the Uninstaller.

Now your Mac camera and audio should be working normally again. Just remember to disable access via System Preferences or web browsers when it isn’t needed, to keep your Mac secure.

Another issue CleanMyMac X can help with:

Staying in control of your camera permissions

Use another tool that’s supplied with CleanMyMac X, it's called Application Permissions. With its help, you can check what apps are allowed to use your camera and adjust those permissions in a few clicks.

Therefore, if you ever have a creepy feeling that someone is watching you, you can easily check it within Privacy and block access to your camera at once.

Note:

You can manage app permissions only on macOS Catalina.

Mac cameras are one of the many system features that are taken for granted. So much so that we forget they are there. Problem is, because of this, they've become a natural security weakness that is being exploited. Taking care to prevent unwanted intrusion is a necessity. We hope this article helps you do that.

Starting with OS X Mountain Lion, Apple introduced Gatekeeper so users couldn’t easily install downloaded apps from outside the Mac App Store.

When someone downloads an app from somewhere other than the Mac App Store they will get one of a few warning messages depending on what security settings they’ve set in System Preferences. We’ll show users how to set the security settings in Security & Privacy section of the OS X System Preferences using any version of OS X after Mountain Lion so they can install downloaded apps from outside the Mac App Store.

Why Can’t I Install 3rd-Party Apps By Default?

If you don’t care about why this works, skip to the next section. Here’s why Apple sets OS X to disallow 3rd-party apps by default, for those who like to understand why things work as they do.

Cynics will say that Apple does this because they don’t get a 30% cut from applications bought directly from third-party apps instead of their curated app store. A $10 app nets Apple $3 and the developer gets only $7. The developer gets the entire $10 if the app is sold directly.

How To Enable Third Party Apps On Mac

Apple says they set things blocking third-party apps because they want to protect users who might install downloaded apps with malware or viruses. They take the 30% cut to cover the cost of hosting the Mac App Store and testing apps to keep malware out of the store. In other words, they want to help protect us from our own mistakes.

Apple offers three setting options in the Security & Privacy Settings in System Preferences. Apple set the default to help protect users from Malware or to lock down computers depending on which explanation you prefer.

Apple created Gatekeeper, a program to protect users from Malware. Developers can get a security certificate from Apple through the Apple Developer program. If a developer distributes their app on the Mac App Store, they have to follow certain guidelines to get approved. These guidelines try to keep malware out of the store. Developers can also add a security certificate to their apps. The certificate is some code inserted into the app code. Users can set their machines to allow third-party apps downloaded from the Internet, but only if they include one of these security certificates.

Uninstall App On Mac Os

Find out how to change the settings below so you can install downloaded apps from trusted third-party websites. Don’t install apps from just any site because relaxing security settings could potentially open the door to malware and viruses.

How to Install Apps from Outside the Mac App Store

To install third-party apps, the user must change a setting in the Security & Privacy section of System Preferences, the Settings app in OS X.

Open OS X System Preferences by clicking on the app icon from OS X Dock or by clicking the Apple icon in the Menu Bar in the upper left corner of the screen. When the menu pops up, click on System Preferences.

Click on Security & Privacy from the top row of the System Preferences app. Choose the General tab to see the settings below.

Mac App To Delete Apps

There’s a lock icon at the bottom of the dialog box. Click it to enable all the settings in the box. The OS will ask the user to enter their administrator’s password. Click OK and the grayed out settings become clickable.

The settings we need to work with show up at the bottom half of the dialog box. There are three options under Allow apps downloaded from:. Here are the descriptions taken from Apple’s support site.

• Mac App Store – Only apps that came from the Mac App Store can open.
• Mac App Store and identified developers (default in OS X) – Only allow apps that came from the Mac App Store and developers using Gatekeeper can open.
• Anywhere – Allow applications to run regardless of their source on the Internet (default in OS X Lion v10.7.5); Gatekeeper is effectively turned off. Note: Developer ID-signed apps that have been inappropriately altered will not open, even with this option selected.

If the user chooses the first two options, they can close the dialog box and continue. However, if the user chooses Anywhere, the above warning pops up to scare the user from using this setting. It says:

Choosing “Anywhere” makes your Mac less secure.

The warning box explains that OS X resets this setting after 30 days. Users will have to come back here and do the above steps again. Further, it explains that it’s safer to let the OS warn you each time you launch an app, which includes an option to allow it by clicking an OK button if you select the middle option of the three.

Which Option Should You Choose?

Those who only install apps from the Mac App Store should not bother changing the default settings. Make sure to select the first option labelled Mac App Store and close the box. If you want to install and run any app you want and don’t worry at all about malware, then choose the third option labelled Anywhere. I use the second option since I can still install third-party apps, but they have to come from developers who take the time to add an Apple Developer security certificate to their app. These are safe, but can come from outside the Mac App Store.
