Unlocking Desktop Audio Recording on Mac with OBS: A Step-by-Step Guide

Are you a Mac user struggling to record desktop audio using OBS (Open Broadcasting Software)? You’re not alone. Many Mac users face this issue due to the software’s default settings and macOS’s security features. In this article, we’ll walk you through the process of allowing OBS to record desktop audio on your Mac, ensuring you can capture high-quality audio for your recordings, streams, and podcasts.

Understanding the Issue: Why OBS Can’t Record Desktop Audio on Mac

Before we dive into the solution, it’s essential to understand why OBS can’t record desktop audio on Mac by default. The primary reason is due to macOS’s security features, which restrict applications from accessing system audio without explicit permission. Additionally, OBS’s default settings don’t allow it to capture desktop audio, requiring manual configuration.

System Requirements and OBS Version

To record desktop audio on Mac using OBS, ensure you meet the following system requirements:

  • macOS High Sierra (10.13) or later
  • OBS Studio version 25.0 or later

If you’re running an earlier version of OBS, update to the latest version to access the necessary features.

Method 1: Using the Built-in Audio Driver (BlackHole)

The first method involves using the built-in audio driver, BlackHole, to route system audio to OBS. This method is free and doesn’t require any additional software.

Installing BlackHole

To install BlackHole, follow these steps:

  1. Open the Terminal app on your Mac. You can find it in the Applications/Utilities folder or use Spotlight to search for it.
  2. Copy and paste the following command into the Terminal window: brew install blackhole
  3. Press Enter to execute the command. This will install BlackHole using Homebrew.
  4. Once the installation is complete, restart your Mac.

Configuring BlackHole

After restarting your Mac, configure BlackHole to route system audio to OBS:

  1. Open the Audio MIDI Setup app on your Mac. You can find it in the Applications/Utilities folder or use Spotlight to search for it.
  2. Click on the “+” button at the bottom left corner of the window and select “Create Multi-Output Device.”
  3. Name the new device “BlackHole” and select the “BlackHole” driver.
  4. Click on the “Use” button to set the BlackHole device as the default system output.

Configuring OBS

Now, configure OBS to use the BlackHole device:

  1. Open OBS and go to Settings > Audio.
  2. In the “Mic/Auxiliary Audio Device” dropdown menu, select “BlackHole.”
  3. Set the “Sample Rate” to 44.1 kHz or 48 kHz, depending on your system’s default sample rate.
  4. Click on the “Apply” button to save the changes.

Method 2: Using a Third-Party Audio Driver (iShowU Audio Capture)

The second method involves using a third-party audio driver, iShowU Audio Capture, to route system audio to OBS. This method requires a one-time purchase of the software.

Installing iShowU Audio Capture

To install iShowU Audio Capture, follow these steps:

  1. Download the iShowU Audio Capture software from the official website.
  2. Open the downloaded .dmg file and follow the installation prompts.
  3. Once the installation is complete, restart your Mac.

Configuring iShowU Audio Capture

After restarting your Mac, configure iShowU Audio Capture to route system audio to OBS:

  1. Open the iShowU Audio Capture app on your Mac.
  2. Click on the “Preferences” button and select the “Audio” tab.
  3. In the “Output” dropdown menu, select “OBS.”
  4. Click on the “Apply” button to save the changes.

Configuring OBS

Now, configure OBS to use the iShowU Audio Capture device:

  1. Open OBS and go to Settings > Audio.
  2. In the “Mic/Auxiliary Audio Device” dropdown menu, select “iShowU Audio Capture.”
  3. Set the “Sample Rate” to 44.1 kHz or 48 kHz, depending on your system’s default sample rate.
  4. Click on the “Apply” button to save the changes.

Troubleshooting Common Issues

If you encounter any issues while recording desktop audio on Mac using OBS, try the following troubleshooting steps:

  • Ensure that the BlackHole or iShowU Audio Capture device is selected as the default system output.
  • Check that the OBS audio settings are configured correctly.
  • Restart your Mac and OBS to ensure that the changes take effect.
  • If you’re using a third-party audio interface, try disabling it and using the built-in audio driver instead.

What is OBS and how does it help with desktop audio recording on Mac?

OBS, or Open Broadcasting Software, is a free and open-source software for video recording and live streaming. It is widely used for its versatility and ability to capture high-quality video and audio. OBS helps with desktop audio recording on Mac by allowing users to select and record specific audio sources, such as system audio or microphone input, and save them as separate audio files or mix them together.

OBS is particularly useful for Mac users who want to record their desktop audio, as it provides more advanced features and customization options compared to the built-in QuickTime Player or other screen recording software. With OBS, users can adjust audio settings, add filters, and even record multiple audio sources simultaneously, making it a powerful tool for podcasters, YouTubers, and anyone who needs to record high-quality audio on their Mac.

What are the system requirements for running OBS on Mac?

To run OBS on Mac, you’ll need a computer with macOS 10.13 (High Sierra) or later, a 64-bit processor, and at least 4 GB of RAM. OBS is compatible with both Intel-based and Apple Silicon Macs, but some features may not work properly on older systems. It’s also recommended to have a dedicated graphics card, especially if you plan to record high-resolution video or use resource-intensive plugins.

Additionally, make sure you have the latest version of OBS installed, as newer versions often include bug fixes, performance improvements, and new features. You can check the OBS website for the latest version and system requirements. If you’re unsure about your Mac’s specifications or compatibility, you can check the Apple Support website or contact Apple support for more information.

How do I download and install OBS on my Mac?

To download OBS on your Mac, go to the official OBS website and click on the “Download” button. Select the macOS version and choose the installation package that matches your Mac’s processor architecture (Intel or Apple Silicon). Once the download is complete, open the installation package and follow the prompts to install OBS.

During the installation process, you may be asked to grant OBS permission to access certain system resources, such as the camera or microphone. Make sure to grant these permissions to ensure that OBS functions properly. After installation, you can launch OBS from the Applications folder or use Spotlight to search for it.

How do I set up OBS to record desktop audio on my Mac?

To set up OBS to record desktop audio on your Mac, launch the software and create a new scene by clicking the “+” button in the bottom left corner of the screen. Then, click on the “Audio” tab and select the audio source you want to record, such as “System Audio” or “Microphone/Auxiliary Audio Device”. You can also add multiple audio sources and adjust their levels and settings as needed.

Next, go to the “Settings” menu and select the “Output” tab. Choose the audio format and quality you want to record, such as MP3 or WAV, and set the output file path. You can also adjust other settings, such as the sample rate and bitrate, to customize your recording. Once you’ve set up your audio settings, you can start recording by clicking the “Start Recording” button.

Can I record both system audio and microphone input simultaneously with OBS?

Yes, OBS allows you to record both system audio and microphone input simultaneously. To do this, create a new scene and add two audio sources: one for system audio and one for microphone input. You can adjust the levels and settings for each audio source separately, and OBS will mix them together into a single audio file.

When recording both system audio and microphone input, make sure to adjust the levels and settings carefully to avoid distortion or echo. You can also use the “Audio Mixer” feature to adjust the levels and settings in real-time while recording. Additionally, you can use the “Advanced Audio Settings” feature to customize the audio routing and mixing options.

How do I troubleshoot common issues with OBS on Mac?

If you encounter issues with OBS on your Mac, such as audio distortion, dropped frames, or crashes, try restarting the software or your computer. You can also check the OBS logs for error messages and try updating to the latest version. Additionally, make sure your Mac meets the system requirements and that you have the necessary permissions and access rights.

If you’re experiencing audio-related issues, try adjusting the audio settings or using a different audio source. You can also try resetting the OBS settings to their default values or seeking help from the OBS community forums or support resources. If none of these troubleshooting steps resolve the issue, you may want to consider seeking help from a professional or contacting Apple support.

Are there any alternative software options for desktop audio recording on Mac?

Yes, there are alternative software options for desktop audio recording on Mac, such as QuickTime Player, GarageBand, and Audacity. QuickTime Player is a built-in screen recording software that can also record audio, while GarageBand is a digital audio workstation that can be used for recording and editing audio. Audacity is a free, open-source audio editing software that can also be used for recording audio.

However, OBS offers more advanced features and customization options compared to these alternatives, making it a popular choice among podcasters, YouTubers, and other content creators. Additionally, OBS is free and open-source, making it a cost-effective option for those who need to record high-quality audio on their Mac.
