    Yes, mac’s built-in recorder can’t capture system sound, which is a pain. I use aisessoft screen recorder—it records screen, system audio, and mic together without any hassle!

    I got it here:  https://www.osxmac.com/screen-recorder-review

    Worth a try!

The built-in screencapture command of macOS can record screen on mac with sound, but does not support direct video recording. However, you can combine sox (a powerful audio processing tool) to record microphone audio and manually synthesize audio and video.

Step 1: Record the screen
The built-in screencapture command of macOS supports recording the screen:

screencapture -C -v screen.mov

-C: Include the mouse pointer.

-v: Record video (macOS Mojave and above).

Step 2: Record microphone audio
Install sox:

brew install sox

Then run:

rec -r 44100 -c 2 -b 16 audio.wav

-r 44100: Set the sampling rate to 44.1kHz (CD level).

-c 2: Stereo audio.

-b 16: 16bit sampling bit depth.


Step 3: Combine audio and video

ffmskpeg -i screen.mov -i audio.wav -c:v copy -c:a aac final_video.mp4

This command will merge audio audio.wav into screen.mov and generate final_video.mp4.

If you want to record screen on mac with audio, the command line method is a bit more complicated, but it can be done.
