Feb 27, 2011 The option key modifier turns the menu option into alternate choices, in this case “Force Quit” instead of “Quit”. This can be helpful if you need to quickly Force Quit a Mac app but the other force quit options aren’t available for whatever reason. Many users will find this Dock trick to be faster too, which is ok because it’s very easy, and the Dock is basically always open. Mar 22, 2016 What to do when a Mac OS X app crashes. The good news here is that a crashed app rarely brings down your entire Mac, as the trouble is restricted to that particular piece of software. That means we have a chance to recover. Let’s start with the simplest solutions. First, just relaunch the app. When an app crashes, you’ll typically see a.

Force quit the app, then open it again
- iPhone, iPad, iPod touch: Force the app to close.
- Apple Watch: With the app open, press and hold the side button to show the power options. Then press and hold the Digital Crown to quit the app.
- Apple TV: Double press the TV/Home button and swipe left or right to find the app with the issue. Then swipe up to close the app. You can’t force apps to quit on Apple TV (3rd generation).
Restart your device
Restart your iPhone, iPad, iPod touch, Apple Watch, or Apple TV. Then open the app to see if it works as expected.
Check for updates
Make sure that your device has the latest version of iOS or iPadOS, watchOS, or tvOS. Then check for app updates.
- iPhone, iPad, iPod touch, or Apple Watch: You can manually update apps. You might need a Wi-Fi connection to update some apps on your iPhone, iPad, or iPod touch.
- Apple TV: Go to Settings > Apps and turn on Automatically Update Apps. If you don't have automatic updates turned on, you can open the App Store, go to the Purchased tab, and open an app's product page to see if an update is available.
Reinstall the app
- iPhone, iPad, iPod touch: Open the Settings app. Tap General, then tap iPhone Storage (or iPad Storage). Tap the affected app, then tap Offload app. Tap Offload app again. Wait a moment for the app to offload, then tap Reinstall App.
- Apple TV: Highlight the app on the Home screen, then press and hold the Touch surface until the app jiggles. Press Play/Pause, then select Delete. Open the App Store and redownload the app. Some apps require subscriptions for activation. If you can't activate the app or you don’t remember your sign-in information, contact the app developer.
- Apple Watch: Open the Watch app on your iPhone and tap the My Watch tab. Scroll to the app you want to remove, then tap it. Turn off Show App on Apple Watch, and wait for it to disappear from your watch's Home screen. To reinstall the app, scroll down to Available Apps in the My Watch tab and tap Install.

The 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.
Using lsof to Find Out What App is Using Your Webcam
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). 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.
Quitting Apps Using Your Webcam
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:
Using Oversight To Get Notified When Your Webcam Is Enabled
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.
Conclusion
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.
