If you are thinking of how to split screen on mac, the procedure is quite straightforward and is a feature in macOS. Launch the first application you want to work with, then hover your mouse pointer over the green full-screen button in the top-left corner of the window. You will see options “Tile Window to Left of Screen” or “Tile Window to Right of Screen. ” Select one of these now, then pick another open application to occupy the remaining space. That split view capability is a very good way to help you get more done by multitasking, to easily compare documents, take notes while browsing, or have several programs running next to each other.
