Mac OS: NDI Virtual Input Video Not Available in Microsoft Teams and Zoom Platforms – NewTek Knowledge Base

A recent security change introduced in Microsoft Teams and Zoom can now prevent users from utilizing unsigned drivers in each platform on the Mac OS, starting with the build dates outlined below. If NDI Video is missing but you find that NDI Audio is still an option in the telecom application, you may need to utilize Xcode to remedy this matter.

Microsoft Teams 1.3.00.33671 (March 5, 2021)

Zoom version 5.0+ (April 27, 2020)

For each, you'll need to first install Xcode as outlined below:

1. Update and Quit Zoom.

2. Launch Terminal.

3. Run xcode-select --install

4. Launch xcode

For Microsoft Teams run:

sudo codesign --remove-signature "/Applications/Microsoft Teams.app"; sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper.app"; sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (GPU).app"; sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (Plugin).app"; sudo codesign --remove-signature "/Applications/Microsoft Teams.app/Contents/Frameworks/Microsoft Teams Helper (Renderer).app"

For Zoom run:

codesign --remove-signature /Applications/zoom.us.app/

After running the code above, relaunch the application and confirm that "NDI Video" populates in the camera/webcam dropdown menu.
