Many apps on Apple Mac support split-screen browsing mode, in which users can work in two apps side by side at the same time.
1. On a Mac, move the pointer to the green button in the upper left corner of the window, and then choose "Match window to the left of the screen" or "Match window to the right of the screen" from the menu that appears.
2. On the other side of the screen, tap the second App you want to use.
3. In the split-screen browsing view, please perform any of the following operations:
Make one side bigger: Move the pointer over the divider in the middle, then drag it to the left or right. To return to the original size, double-click the divider bar.
Swap the position of the app on the screen: use the toolbar of the window to drag the window to the other side. If you don’t see the toolbar, click the window and move the pointer to the top of the screen.
Show or hide the menu bar: Move the pointer to or away from the top of the screen.
Show or hide the Dock: Move the pointer to or away from the position of the Dock.
4. To stop using the app in the split-screen browsing view, click its window to display the menu bar, move the pointer to the green button in the upper left corner of the window, and then choose "Exit Full Screen" from the menu that appears or click Button.
The remaining app will expand to full screen and can be accessed from the space bar. To stop using the app in full screen mode, move the pointer over the app thumbnail in the space bar, and then click the exit button that appears in the upper left corner of the thumbnail.
If you are already using an app in the full-screen view, you can quickly select another app to work in the split-screen browsing view. Press the Control-up arrow key (or swipe up with three or four fingers) to enter the dispatch center, drag a window from the dispatch center to the thumbnail of the full-screen app in the space bar, and then click "Split screen browsing "Thumbnail. You can also drag the thumbnail of one app to the thumbnail of another app in the space bar.
To use the App in split-screen browsing view on other monitors, please make sure to select the "Monitor has a separate space" checkbox in the "Control Center" preferences.
