You join a call and your face is not where you left it. The Mac has quietly switched to the iPhone lying on your desk, so you are broadcasting the ceiling, or your own ear, or a very close view of a coffee cup. Continuity Camera did that deliberately. There are four ways to stop it, and they differ mostly in how long the fix lasts.

The quick answer: open the camera list in whatever app you are calling from and pick the Mac's own camera, usually listed as FaceTime HD Camera. That fixes the call you are on, in one click. To stop it in every app for good, pick up the phone and turn off Settings > General > AirPlay & Continuity > Continuity Camera. The switch is on the iPhone, not on the Mac. And if what you actually wanted was a photo from the phone on your Mac, that is a different job with a faster answer. Free for iPhone Free for Mac

Switching the camera inside Zoom or Teams gets your Mac webcam back

Zoom hides its camera list behind the small arrow next to Stop Video. Every Mac video app keeps a list like it, and a nearby iPhone is only ever one entry in that list.

Start here, because it takes one click, it works in the middle of a live call, and it changes nothing on the phone. Every video app on a Mac keeps its own camera list, and a nearby iPhone is only ever one entry in it.

If you would rather never think about this again, the permanent fix is the Continuity Camera switch on the iPhone, further down this page.

Camera to Clipboard puts a phone photo on the Mac clipboard to paste

Switching Continuity Camera off gives you your webcam back and nothing more. It does not help with the other reason a phone ends up propped against a Mac, which is getting a picture off the phone and into whatever you are writing. That job has its own answer, and it does not mind whether the computer is a Mac.

  1. Install Camera to Clipboard on the phone and the desktop app on the Mac.
  2. Pair them once by scanning a QR code, about ten seconds.
  3. Take or pick a photo on the phone and send it.
  4. Press Cmd + V on the Mac.

Turn off Continuity Camera on the iPhone, not on the Mac

The switch is on the iPhone, not on the Mac. Turning Continuity Camera off here stops the phone presenting itself as a webcam to every Mac you own, which no Mac setting can do.

This is the permanent fix, and it is on the phone. People lose a long time to this, because the feature takes over a Mac and every instinct says the setting must be on the Mac too. Four taps:

  1. On the iPhone, open Settings.
  2. Tap General.
  3. Tap AirPlay & Continuity.
  4. Turn Continuity Camera off.

Moving the iPhone away or unlocking it releases the Mac camera

Sometimes you are already on the call and you do not want to go digging through settings on either device. The conditions this feature needs are strict, and breaking any one of them hands the camera straight back.

Turning off Handoff stops Continuity Camera and Universal Clipboard

This is the blunt instrument, and it is the one people reach for too early. Handoff is the switch that several Continuity features sit under, so turning it off takes far more than the camera with it.

Illustration of Universal Clipboard failing: a phone shows Copied but the laptop shows Paste Failed with nothing in the clipboard
With Handoff switched off, a copy on the phone simply never arrives on the Mac. That is the trade for turning the whole family off at once.

Only the webcam half of Continuity Camera interrupts a video call

Apple gave one name to two different features, which is why half the advice about Continuity Camera does not match the problem you have. Here is which is which, briefly.

Insert from iPhone only runs when you pick it from a Mac menu

If the Continuity Camera you were worried about is the one that opens the iPhone camera from a Mac document, you can leave it alone. It has no automatic behaviour to switch off.

The iPhone toggle is the only way to stop Continuity Camera for good

Four different ways stop a Mac using the iPhone as its camera. What separates them is how long the fix lasts and how much else it switches off.

Way to stop it How long the fix lasts How fast it is to do What else it switches off Where you change it
Camera list inside the video app That one app, until you change it back One click, mid call Nothing else On the Mac, inside the app
Continuity Camera switch on the iPhone Every app and every Mac, until switched back Four taps on the phone Nothing else, Handoff survives On the iPhone, in Settings
Unlock the iPhone or tap Disconnect This call only Seconds, no menus at all Nothing else On the iPhone screen
Handoff switched off Every app and every Mac, until switched back One switch in System Settings Universal Clipboard and app handoff On the Mac, in System Settings

Switch cameras in Zoom during a call, or turn Continuity Camera off

Which of the four fixes you want depends on one thing, which is whether a video call is running on the Mac right now or you are setting the Mac up properly for next month. Find your situation below.

Common questions about turning off Continuity Camera on a Mac

How do I stop my Mac using my iPhone as a webcam?
Open the camera list in the app you are calling from and choose the Mac's built-in camera. FaceTime keeps that list in its Video menu, and Zoom keeps it behind the small arrow next to Stop Video. To stop it happening in every app instead of just that one, turn off Continuity Camera on the iPhone under Settings > General > AirPlay & Continuity.

Where is the Continuity Camera setting on a Mac?
There is not one. macOS has no Continuity Camera switch anywhere in System Settings, which is why searching the Mac for it comes up empty. All the Mac lets you do is pick which camera an app uses. The switch that stops the iPhone offering itself lives on the iPhone, in Settings > General > AirPlay & Continuity.

Does turning off Continuity Camera also stop Universal Clipboard?
No. The Continuity Camera switch on the iPhone affects the camera and microphone only, and AirDrop, Handoff and Universal Clipboard all keep working. Universal Clipboard stops only if you turn Handoff off, which is a separate switch and a much broader one.

Why does my Mac keep switching back to the iPhone camera?
Moving the phone away, unlocking it or tapping Disconnect releases the camera for that call only and changes no setting. The next time the iPhone is sitting still and idle near the Mac, it offers itself again. Only turning off Continuity Camera on the iPhone stops that happening for good.
