Want to record internal audio (system sounds) on your Mac? macOS makes this challenging due to strict security settings. This guide explains the most common solutions — from complex manual setups like BlackHole to the easiest option: using ShotVu, a browser-based screen recorder that captures everything, including system audio, with no installation.
How macOS Handles Audio
On macOS, input devices (like microphones) are separated from output devices (like speakers). Most screen recorders can only access input sources. System audio flows through the output channel, meaning it’s invisible to traditional screen recording software. To bridge this, virtual drivers or browser-based solutions like ShotVu are needed.
BlackHole – A Free but Manual Workaround
BlackHole is a virtual audio driver that lets you reroute system sound to be captured. It’s free, but setup is manual and technical. You must install the driver, configure Audio MIDI Setup, and create a Multi-Output Device. Then, manually switch your system output and configure your screen recorder to use BlackHole as an input.
Setting Up Audio MIDI for BlackHole
To use BlackHole effectively, open Audio MIDI Setup and create a Multi-Output Device that includes both your speakers and BlackHole. Enable Drift Correction for stability, and make sure your screen recorder listens to the BlackHole input. While functional, this method is time-consuming and error-prone for non-technical users.
Using QuickTime Player with BlackHole
QuickTime doesn’t support internal audio natively. By using BlackHole as the selected microphone input, you can record system sound — but it only works after configuring your system audio output to the virtual device. It’s not ideal for quick or repeat recordings, and many users forget to revert their settings afterward.
OBS Studio – Power and Complexity
OBS is an advanced, open-source screen recording app. It supports more audio control and may work with system sound using built-in features or plugins. While powerful, OBS has a steep learning curve and isn’t beginner-friendly for simple recordings. It’s best suited for streamers and developers.
Loopback – A Paid Pro-Level Option
Loopback ($99) lets you route audio from any app into a virtual input device. It's intuitive and reliable, great for podcasters or complex setups. However, it’s overkill for basic screen recordings. If you just want to capture your screen and internal sound quickly, it’s not the most efficient choice.
