I wasn't able to install either WavTap or Soundflower since they're blocked by El Capitan. I tried using iShowU but the guide was confusing and left out some steps so I was left with no sound at all instead of only microphone sound. Anyway, I'm trying to record using a headset with a built-in microphone and getting no desktop audio and was hoping someone could help me. I'm using OBS 0.14.2 and El Capitan 10.11.4.
