How to Record Your Mac Screen with Internal Audio

Record the sound already playing on your Mac — internal audio from apps and the system — into a screen recording.

Internal audio is the sound the Mac is already playing: a browser tab, a call in another app, music, or a video. It is not your voice. In Shoverlay the control is named system audio.

Turn on system audio

Start a screen recording of an area, a window, or the full display.
In Recording settings, turn on system audio.Leave the microphone off.
Choose MP4 or MOV.GIF and animated WebP do not keep this soundtrack.
Stop from the recording toolbar.

System audio uses Screen Recording permission on supported macOS versions. Allow it, then quit Shoverlay and open it again.

If the clip is silent

System audio is off in Recording settings.
The Mac is muted, or the app you are recording has its own volume at zero. Check System Settings → Sound.
The file is a GIF or an animated WebP.

A mono mix combines the channels. Your voice is the microphone track, and it stays off for this job.

Install Shoverlay on the Mac App Store.
