Highlighting the importance of Microphone permissions on Mac

[arisolt]

Hi guys,

Thanks a lot for this super useful tool. Just wanted to suggest that the importance of granting Microphone permissions on Mac is highlighted more clearly in the instructions. In reality this enables Sonobus to receive from any interface, including e.g Soundflower.

I originally declined granting the permissions because I assumed it actually meant Microphone access (and I don't even have a microphone). It took me 1.5 days to figure out why Sonobus was dead quiet and didn't seem to be working at all.
