Fixed the Background Music audio device not being loaded immediately after installation on macOS Catalina. (The installer now tries an additional method of restarting coreaudiod so it will load BGMDriver)
Love this app! Simple and easy to use, does everything I needed it to and even helped me with quiet movie files on my old MacBook. In comparison to similar apps costing over 50$, this is stellar. I use it with XCode 12.4 on Catalina. Go to the GitHub if there are any problems; the explanation there is straight forward.
