Use apps in full screen on Mac
Many apps on your Mac support full-screen mode—an app fills the entire screen—so you can take advantage of every inch of the screen and work without desktop distractions.
On your Mac, move the pointer to the green button in the top-left corner of the window, then choose Enter Full Screen from the menu that appears or click the button .
In full screen, do any of the following:
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 Dock’s location.
Move between other apps in full screen: Swipe left or right on the trackpad. See Use trackpad and mouse gestures.
To stop using the app full screen, move the pointer to the green button again, then choose Exit Full Screen from the menu that appears or click the button .
