Fix OBS Virtual Camera Permissions on macOS

If your macOS applications cannot detect or access the OBS Studio virtual camera, the issue is typically caused by strict macOS privacy settings, outdated software, or system-level library validation blocks. This guide provides clear, step-by-step instructions to resolve these permission conflicts so you can seamlessly use your OBS virtual camera in communication apps like Zoom, Microsoft Teams, and Discord.

Update OBS Studio to the Latest Version

Older versions of OBS Studio used legacy camera plug-ins (DAL devices) that macOS Sonoma (14.0) and later block by default.

  1. Launch OBS Studio.
  2. Click OBS Studio in the top menu bar and select Check For Updates.
  3. Install any available updates. Modern versions of OBS Studio (version 30.0 and newer) use Apple’s modern camera extension system, which resolves most permission and detection issues automatically.

Grant Camera Permissions to Host Applications

The OBS virtual camera does not require camera access itself; rather, the applications trying to use the virtual camera (like Chrome, Zoom, or Discord) must have permission to access cameras on your Mac.

  1. Click the Apple menu in the top-left corner of your screen and select System Settings (or System Preferences on older macOS versions).
  2. Navigate to Privacy & Security in the sidebar.
  3. Click on Camera in the right-hand pane.
  4. Locate the application you want to use with OBS (e.g., Discord, Zoom, or your web browser) and toggle the switch to the On position.
  5. Restart the target application for the changes to take effect.

Re-register the OBS Virtual Camera

If the virtual camera still does not appear in your applications, you can force macOS to register the plug-in again.

  1. Open OBS Studio.
  2. Click the Start Virtual Camera button in the Controls dock on the bottom right.
  3. If prompted for your macOS administrator password, enter it to allow OBS to install the necessary system extension.
  4. If it is already running, click Stop Virtual Camera, wait a few seconds, and click Start Virtual Camera again to refresh the connection.

Restore Legacy Camera Support (macOS Sonoma and Later)

If you are using an older application that does not support modern macOS camera extensions, you may need to manually restore support for legacy virtual cameras.

  1. Turn off your Mac.
  2. Boot into Recovery Mode:
    • For Apple Silicon (M1/M2/M3) Macs: Press and hold the Power button until the startup options screen appears, click the Options gear, and click Continue.
    • For Intel Macs: Press the Power button and immediately press and hold Command (⌘) + R until the Apple logo appears.
  3. In the top menu bar, go to Utilities > Terminal.
  4. Type the following command exactly and press Enter: system-override legacy-camera-plugins-without-warning
  5. Restart your Mac normally. This will bypass the restriction blocking legacy camera plug-ins on newer macOS versions.

Fix Library Validation Issues (for Discord, Slack, and Teams)

Some applications use Apple’s “Library Validation” security feature, which prevents them from loading third-party plugins like the OBS Virtual Camera. If the camera works in FaceTime but not in Discord or Teams, this is the cause.
