I am trying to use my Canon XC15 via to my MacBook Air (High Sierra v10.13.6) to livestream on Facebook/YouTube, but I can't get my Mac to detect it. Is there a way to do this that doesn't involve purchasing external hardware like BlackMagic/Magewell? I downloaded CamTwist and Camera Live to use in combo (based on a YouTube vid I watched), but it's not working. I'm not sure if I'm doing something wrong, or if my camera isn't supported by that software. Full disclosure: I'm kind of learning all this on the fly so I'm not especially knowledgeable on a lot of the technical aspects of all this. Thanks.
