TIL: how to uninstall a virtual camera plugin on macos

If you previously installed a camera assistant app that added a virtual camera on macOS, you may still see that camera as an input option even after uninstalling the app. This can happen because the app leaves behind a plugin file.

To fully remove the plugin:

1. Open Finder and go to /Library/CoreMediaIO/Plug-Ins/DAL
2. Look for the plugin from the app you want to remove.
3. Move it to the trash.

Trashing the plugin file will ensure the virtual camera created by an app is completely uninstalled and no longer available as a camera input option
