Here we will discuss potential reasons and solutions to help you get your split screen working smoothly.

Key Reasons Why Your Mac Can't Do a Split Screen

Check for Hardware Limitations: Some Mac systems might have hardware limitations that prevent split screen from working. Check if your Mac model supports split screen. Reset NVRAM/PRAM: If none of the above solutions work, resetting your NVRAM/PRAM might help. To do so, shut down your Mac, then turn it on and immediately press these keys together: Command Option P R until you hear the startup sound twice.
