Download for MacOS - server 1 --> $7.99The world of digital security can be a scary one. With hackers in the news and a big ransomware scare just recently wrapping up, folks have good reason to be concerned. Staying secure online is crucial, and it starts with good security habits. But what if you're concerned that someone is spying on you through your Mac's webcam? Can you find out if a rogue app is accessing your Mac's webcam?
It isn't just an idle question. Not too long ago, there was a fad among troublemakers and hackers to make online 'slaves.' It sounds worse than it actually is: basically, dumb kids (and some childish adults, I'm sure) would take over the webcams of unsuspecting targets and watch them go about their day. Sometimes, they would catch glimpses of people undressing, but the point was to invade someone's privacy. This was based on a Windows exploit, but a ounce of prevention is worth a pound of cure.
The 'stock' way to find out which app is using your webcam on a Mac is, unfortunately, not excellent. It requires some Terminal commands and a little bit of computer know-how. There are simpler ways that use off-the-shelf software, which we'll cover below. If you're comfortable with Terminal, however, you can use the Terminal command lsof to get a list of applications currently attempting to access your webcam.
1. Open Terminal (Applications/Utilities/Terminal.app).
2. If you have a built-in webcam (like with a MacBook Pro or iMac), copy and paste the command below and press 'Enter.' You can also type in the command, but be sure to be 100% accurate.
If you have a third-party webcam (like a Logitech model) copy and paste the following command and press 'Enter.'
If you're curious about what's happening, we're the lsof command tells you what process or application is using a specified system resource. By running lsof 'naked,' or without flags, we would normally get a list of all the processes doing just about anything on our Mac. Then, we search through that list using grep to find references to the appropriate webcam interface.
3. In this case, the command will return a list of all the applications currently using (or thinking about using) your webcam.
Annoyingly, this list will likely include some extraneous applications. You'll see stuff like the third-party software that runs your camera (if any). Office 365 mac access database. You'll also often see Google Chrome listed. Even with this imperfect list, however, you'll have a place to start scanning for suspicious or unexpected applications to investigate.
This list, though cryptic looking, is decipherable. If you look at the beginning of each line, you'll see some familiar program names: in this case, Google and FaceTime. There's also some unusual ones, like LCore and something called 'avconfere.' Let's investigate the odd ones.
4. To find out more about this processes, I can us the ps -p command, along with the process ID. The process ID is the number next to each program's name, and it's just a number that allows you to specify which particular program you want to investigate with Terminal.
5. For example, the following command will tell me more about the LCore process:
If you're curious about what we're doing, the -p flag allows us to use ps to investigate the origin and status of a running process as specified by its process ID.
6. As we can see, that's the Logitech kext that's running my Logitech webcam, so that's no danger. I can tell thanks to the location of the file, as well as a little Googling to confirm my suspicions.
7. Let's try the same trick on the 'avconfere' process using the command below:
8. That actually 'avconferenced' which is the daemon that handles all webcam requests on macOS, so that's also safe too. I know this because I Googled it, which you should do for any unusual processes. I also suspect it's safe because it's in the 'libexec' folder, which contains system daemons and utilities. Of course, a clever attacker might disguise their process in that way, so always investigating anything you don't recognize or understand.
If you do find a malicious application, you can quit it from the command line using the kill command.
1. Use the above process to determine the process ID of the application using your webcam.
2. Type kill #### where #### is the process ID of the application you want to quit. For example, to kill Chrome, I would type the following:
lsof has limitations, listing all the apps that might attempt to access your webcam (like Chrome) even if they're not doing so currently. The freeware app, Oversight, which was developed by an ex-NSA hacker, is a good alternative. Oversight will alert you whenever your camera or microphone becomes active, and let you know which application has started using it. You can then approve or deny the usage directly from a notification.
1. Download and install Oversight.
2. When an application wants to use your webcam, Oversight will generate a notification.
3. Click Allow to allow the app to use your webcam, or Block to deny the usage.
There's a couple of ways to find out which application is using your Mac's webcam. And remember that built-in Mac webcams will always show their green 'in use' light when operational. This is thanks to the physical wiring of the device. For power to reach the camera, it must also illuminate the LED. Thanks to this design, it's hard to imagine a software exploit that would disable the light, but caution is rarely regrettable. If you're really freaked out, don't forget the lowest tech solution of all: a piece of tape stuck over your webcam's lens.

If the camera indicator light next to the camera flashes green on your Mac notebook, contact Apple.
If your Mac is using macOS Catalina and you use Screen Time, make sure your camera is turned on and apps that use the camera have time available.
If your Mac is using macOS Mojave or later, choose which apps can use your built-in camera:
Try to use your camera in another app. For example, if you can't use your camera in FaceTime, open Photo Booth.
If you still can't use the built-in camera on your Mac, resetting the SMC might help. Learn how to reset the SMC on your Mac.
If you can't connect to FaceTime, learn what to do if FaceTime isn't working on your Mac.
