Virtual Mic (CueCam Audio)

Before deleting CueCam, remove the Virtual Mic via the Output Menu.

Alternatively, this can be removed by deleting the file at:

/Library/Audio/Plug-Ins/HAL/CueCam Audio.driver

Camera Extension (CueCam)

Deleting CueCam Presenter from your Mac (via Finder) should result in a system prompt to confirm that the camera extension will be removed in the process.

However this macOS feature does not work 100% reliably.

If the camera extension is still present after deleting CueCam

Reinstall CueCam and uninstall the camera extension through Output menu.

Then you can delete CueCam again.
