A Logitech webcam works on a Mac the moment you plug it in — there is no driver to install. Changing its settings is another matter, because macOS has no camera settings at all. Logitech’s old Camera Settings app is discontinued; its current software is Logi Tune, Logi Options+ or G HUB depending on the model. To turn off autofocus and have it stay off, you need something that puts the setting back every time the camera reconnects.
Setting up a Logitech webcam on a Mac
- Plug it in. Logitech webcams implement the standard USB video protocol, which macOS supports out of the box. Nothing to download, no restart.
- Allow the accessory if you are asked. Mac laptops with Apple silicon can ask whether a newly connected accessory is allowed to connect. Until you allow it, the camera does not exist as far as macOS is concerned — which looks exactly like a dead camera.
- Choose it in each app. macOS has no system-wide default camera; every app picks its own. In FaceTime and Photo Booth it is the Video or Camera menu; in Zoom, Settings → Video → Camera; in Teams and Google Meet, the device settings.
- Grant camera access. The first time an app uses the camera, macOS asks. If you declined once, turn it back on in System Settings → Privacy & Security → Camera.
- Pick the microphone too. The C920 and many other Logitech webcams have microphones built in. Choose them — or your usual mic — in System Settings → Sound → Input, or in the app’s own audio settings.
That is the whole setup. Everything past this point is about the picture, and that is where macOS stops helping.
Turning off autofocus on a Logitech webcam
A common reason C920 and Brio owners go looking for settings: the camera keeps hunting for focus every time you move, lean back or lift a mug, and the picture swims in and out.
My webcam was refocusing constantly, and this allowed me to select the focus I wanted so that it was steady and predictable.

In CamDial: open it from the menu bar, turn off Auto on the Focus row, and drag the slider until your face is sharp at the distance you actually sit. The camera holds that focus from then on. The same works for exposure and white balance, which are the other two settings a C920 likes to drift on its own.
In Logitech’s software: Logi Tune offers manual focus for the models on its supported list, which includes the C920, C922 and Brio.
Why autofocus comes back on. Focus mode is a setting that lives in the camera’s volatile memory, not on your Mac. Unplug it, let the Mac sleep, or move it to another USB port, and the camera starts up again at its defaults — with autofocus on, which is why it seems to switch itself back on. In CamDial, save the look as a preset and it goes back on automatically every time the camera reconnects. The full mechanism of why webcams forget is worth ten minutes if this keeps happening to you.
Which Logitech app goes with which camera
Logitech now splits webcam control across three apps, and maintains a support article whose only job is telling Brio owners which one to install. As of September 2026:
| Camera | Logitech’s current app |
|---|---|
| C920, C922, Brio (4K) | Logi Tune; also G HUB |
| MX Brio, Brio 500, Brio 700 | Logi Options+ |
| StreamCam | G HUB |
| Any of these, plus non-Logitech cameras | a UVC control app such as CamDial |
Two things to know before installing more than one. Logitech’s own troubleshooting notes that Logi Tune and G HUB fight over the webcam when both are installed. And every one of these sees Logitech hardware only — the Elgato, Razer or no-name camera on the same desk needs something else.
What happened to Camera Settings
Camera Settings was a small utility that did one useful thing: it exposed the controls that live on the camera itself — exposure, white balance, focus, zoom, brightness, gain — and let you move them. It was the panel that should have shipped with the operating system, which is why people are still hunting for it years later.
It is also why old download links still get traffic. Support pages redirect, forum answers point at builds that no longer exist, and every so often a mirror surfaces with an unsigned copy of a very old release. On a current macOS that is a bad trade: an unmaintained binary from an unverifiable source.
Logi Tune is a different tool, not a successor
Logi Tune is maintained and genuinely fine at what it does — if every camera on your desk has a Logitech logo, it is a sensible thing to run, and it is the only route to firmware updates. But the complaint that follows it on the Mac is the same one that follows every app in this category:
I have to reconfigure my LogiTune settings every time I run Zoom.

That is not really a Logitech failing — it is how webcams work. Settings live on the camera, macOS keeps no record of them, and the app that opens the camera next gets to reconfigure it. Unless something is watching and putting your values back, they go. There is a fuller comparison of CamDial and Logi Tune if you are deciding between them.
CamDial, specifically
CamDial sits in the menu bar and controls any USB (UVC) webcam at the hardware level — Logitech or not — and shows the values in real units, kelvins and fractions of a second, instead of percentages. You save a look as a preset once; when the camera reconnects after a sleep or an unplug, the preset goes back on automatically and the app tells you it happened. A per-app rule handles the other case — when Zoom comes to the front, apply Evening warm. And for an app that keeps adjusting the picture mid-call, a Hold these settings against other apps toggle (Pro) checks the camera twice a second and puts your values back; it is off unless you turn it on, because holding means reading the camera continuously.
Because it changes the camera rather than filtering the video, there is no virtual camera to select. Whatever opens the camera next — Zoom, Google Meet, Teams, OBS, FaceTime — gets the picture you set. It has no network access at all. Free to start; Pro is a one-time unlock, no subscription.
One thing no app can offer you, whichever way you go: the camera built into your Mac. Apple’s FaceTime and Studio Display cameras do not expose hardware controls to any application on macOS. Camera Settings could not touch them either.
