Have you tried out the split screen feature on your Mac? If you’re using El Capitan or above, here’s how to do it.
Open the app. Here, I’ve opened the Safari browser.
Left-click and hold the green button at the top left.
Drag the program to the far left or the far right.
Open a second app. I’ve chosen Maps. Click and hold the green dot and drag it in the opposite direction of the first. The two programs will now share the screen.
Not every app is compatible with split screen, but most are.
