Split Screen on Mac OS

It’s actually really quick to do.

In your open Window hover (top left) and you will see 3 buttons for Close, Minimise and Resize (Red, Orange and Green).

It’s all about the Green button.
​
On older Macs HOLD down the green button and then you can select which half of the screen to move the window to. You then select the second window to tile it to the opposite side.
​

On newer Macs HOVERover the green button and you will see dedicated menu options (Tile, Slip to Left, Spit to Right)
