Re the Mac OS video. We used Soundflower because it's free and doesn't capture any personal information from you. It's also reccomended on the Web SDR faq page: www.websdr.org/faq.html (see the question about decoding digital modes). There are a couple of alternatives though, if the install process is too complicated, have a look at Blackhole and Loopback.
