Open up the Audio MIDI Setup app from Applications > Utilities. This might not be a problem, but if it is, read on. This will indeed capture all “desktop audio” (so you’ll probably want to close or mute email notifications and so on when streaming or recording), but crucially it won’t actually output any sound to your speakers or headphones so you’ll be playing mute. So, step 6 is going into System Preferences > Sound and choosing IShowU Audio Capture as your sound input device, which will work, but keep reading for an additional tweak.Īll you need to do now is open up OBS and choose a new Audio Input Capture source (click the + under the Sources box), then choose IShowU Audio Capture as the device. You don’t need Step 6 yet, so do 1-5 and come back. How to make IShowU work with OBSįirstly, download IShowU Audio Capture from this link, and install it as shown. 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.
