On the flip side, I found that OBS brought my -- admittedly older -- MPB to its knees such that the app I was trying to show wouldn't perform. Huge lengths of video were frozen. Same on an older first-gen i7 Windows machine. I never did figure it out.
This is probably a configuration issue, although OBS has more issues OS X for a variety of reasons. I've ran OBS on my 10 year old PC while coding without much issue.
