When customizing the Mission Control setting, I accidentally disabled “Displays Have Separate Spaces” option. So, when Split Screen was not working on my Mac, I don’t know what suddenly want wrong. I tried out many tricks, but no one was helpful.

I visited Apple Support page and knew that “Displays have separate Spaces” within Mission Control on my Mac was previously disabled, which caused Split View mode to run into issues. I then re-enabled this option and this trick worked perfectly for me in fixing the problem.

So, you should make sure this option is already enabled by heading to System Preferences → Mission Control and check the box for it.


If this option is already turned on, untick the box, restart your computer and enable it again. You can now use the Split Screen as usual and the problem should disappear.

The better is to remove it and make use of Software Update feature on your Mac. Check for the latest MacOS update and install the latest one on your computer.
