There’s a full (paid for) software package called IShowU, but all you need for this purpose is the audio capture part, which is free.
This time, however, I finally looked up how to and in the process came across a new utility which effectively replaces it, and works: IShowU Audio Capture. It irritated me every time I saw it there but was always busy doing something else and kept forgetting to remove it. Soundflower was still in my system settings, albeit unused, and I’d never got round to uninstalling it. Recent versions of OS X have actually prevented Soundflower from working as intended at all, so there was no (free) solution and I stopped using OBS on a Mac. On older Macs, you could run a 3.5mm to 3.5mm cable from the headphone socket to the line in socket, but on newer Macs there’s one socket that does both directions, so that’s out.Ī year or so ago I tried to get either of two solutions working: Soundflower, which sort of did but was really fiddly, and WavTap which never seemed to work at all. On the PC, you can capture “desktop audio” or “what U hear”, but that’s not an option on OS X. I’ve used it quite a lot, but it has frustrated me for a while that the Mac version has – through no fault of OBS – no ability to capture game audio.
OBS (Open Broadcaster Software) is a great program for streaming and recording gameplay on a PC.
