In this lesson for macOS Mojave, I look at how to use split-view when working with apps in full-screen. When you use split-view, you can place two apps or folders side-by-side while in full-screen view on the Mac.
Opening an App or Window in Full-Screen
The first thing you need to do is open an app or folder in full-screen. Once you do that, you can then split that into two views. To open an app or window in full screen, click on the green dot in the upper left corner of the window. When you do this, it will open in its own Space (see Mission Control for more information on Spaces).
Adding an App or Folder for Split-View
Once you have an app in full-screen or in its own Space, open Mission Control. Then drag the app or window you want to view in split-screen onto a Space at the top of Mission Control that has an app or window in full-screen. You can split it on the left or right side depending on where you drag it.
Closing a Split View
To close a split-view, close the window you no longer want to be in the split-view.
