Comment (by ddennedy):

 A problem is that this new API `AVCaptureDeviceDiscoverySession` should
 not be used on older macOS versions. `AVCaptureDeviceTypeExternal` is for
 macOS 14+, but I am building and testing on a system with 12.7 where it
 was working fine. I can confirm this is working with the USB webcam on
 12.7:

 It will take more time for me to verify that iPhone continuity camera is
 fixed with the parenthesis in the macro.
