If you dont want to change your display settings...
I hereby present to you a kinda random fix I came up with while fiddling around with this issue:

#if UNITY_EDITOR_OSX

using UnityEngine;

namespace Utils {
public static class MacVSyncFix {
[RuntimeInitializeOnLoadMethod(RuntimeInitializeLoadType.BeforeSplashScreen)]
public static void Fix() {
QualitySettings.vSyncCount = 2; // Change from default 1 to 2 did the trick
}
}
}

#endif

Just create a file somewhere in the Assets folder and you can now use the Game View's VSync again.
In the builds I did not have any problems.

For me Vsync is totally broken, changing the Refresh Rate down to 60hz (disabling ProMotion), and enabling VSync causes screen tearing, but at least the flickering is gone

I can confirm that for me it's ProMotion breaking it as well

I have found that on my MacBook Pro (M1 Max) the flicker issue only occurs when ProMotion is enabled in Display Settings. If I set my screen to a constant 60hz, the issue does not occur. It seems be only related to ProMotion on the built-in display.
