This issue was not fixed in 2020.3.37. My game still crashes when changing Vsync on MacOS with Metal.

This bug is preventing me from releasing the latest version of my game on MacOS. I'm using Unity 2020 LTS. Really hoping it doesn't take much longer to bring the fix to LTS versions.

Resolution Note (fix version 2023.1.0a2):
Switching vsync mode while in the player could sometimes cause a freeze due to the vsync status not syncing correctly before waiting on the frame present - this has been fixed.
