How To Stream Desktop Audio on Mac Using OBS

I recently learned about “Twitch”, a popular streaming platform, and I decided to try it out to stream some of my Fortnite gameplay.

After doing some research, I discovered that OBS (Open Broadcaster Software) is one of the easiest and most reliable programs to use while streaming off a Mac.

However, after downloading the Software and attempting to stream, I realized that although I could stream the audio from my mic, the desktop audio was not working. I spent an eternity trying to solve this problem, and there was nothing about my situation on the web. Finally, after long hours of experimenting with the settings, figured out how to. So, to put others out of their misery, I decided to compile a five step process WITH PICTURES to help you understand how to stream desktop audio on a Mac using OBS.

1. Download “iShowU Audio Capture”

Click here to download audio capture software, and complete all necessary steps to install.

3. Create “Multi-Output Device” and Select “iShowU Audio Capture” as Master Device

Once this page shows up, click on the plus sign in the bottom left. When the drop-down menu opens up, select “Create Multi-Output Device”. Once you’ve done this, make sure that “iShowU Audio Capture” is the master device, and that its little box below is also selected.

4. Make Sure “Multi-Output Device” is Selected

Click the Apple logo at the top left of your screen and select “System Preferences”. Next, select “Sound”. Once this next screen shows up, make sure that “Multi-Output Device” is selected.

5. Open OBS Settings and Set Audio to “iShowU Audio Capture”

For the final step, launch OBS. If you don’t already have OBS downloaded, check out how to do it in this tutorial. Next, click on the “Settings” button on bottom right, as performed in picture. After the settings screen opens, click on “Audio”, and then open the drop down menu for “Mic/Auxiliary Audio Device 2”, then select “iShowU Audio Capture”. After you’ve completed all of these steps, click “OK” at bottom right.

 

 

 

My Gaming Setup:

If you are thinking of becoming a streamer or just want to get into gaming, here are some personal recommendations for gaming accessories.

1. Sades A70 Headset

My favorite headset is the Blue Sades A70, because though they are not wireless the sound quality is outstanding and these are also extremely comfortable and satisfying to wear.

2. Logitech G300S Mouse

This is my favorite gaming mouse not only because of the awesome rainbow lights that it displays, but also because of the amazing fit in your hand. To top that off, it also has 9 programable buttons, which are way more than the average gaming mouse.

Buy on Amazon

3. MacBook (With NVIDIA GeForce Now)

You’re probably wondering how a MacBook could possibly run any high def games. I use “NVIDIA GeForce Now” to run my games extremely smoothly. It works amazingly, and I can run at high FPS with max resolution settings.
