I want to capture my screen, so I'll use index 1 (IE: [1] Capture Screen 0). Below command will record a video of your screen.

ffmpeg -f avfoundation -i "1:0" output.mkv

Convert the video to a format that can be played by QuickTime player (probably don't need this step if you have a video player capable of playing .mkv but I didn't)

ffmpeg -i output.mkv -c:v prores_ks -profile:v 3 -c:a pcm_s24le output.mov
Notes


https://trac.ffmpeg.org/wiki/Capture/Desktop for guidance
If you get errors running the above commands, on your system settings, check the following:

Privacy and Security | Screen Record - ensure your terminal application is allowed to record screen
Privacy and Security | Microphone - ensure your terminal application is allowed to capture mic input (I guess this is optional if you don't care about sound)
