Click the green zoom button in a Mac window and it not only gets bigger, it goes full screen– and it’s so full-screen that the menu bar’s taken away. That’s not what most of us expect– especially if you’re used to the way that button used to work (it zoomed, but it left the menu bar alone).
Turns out you can make the green button behave the zoom-but-don’t-hide-the-menu-bar way by holding the Option key down while you click it. Apple gives you a tiny visual clue that holding the Option key will give you a different result– try hovering over the green button with and without the Option key held down.
Sometimes bigger isn’t better. This is one of those times.
(If you click the green button without the Option key, bring the menu bar back by pressing the Escape key at top left of your keyboard. There are other ways but that’s for another post.)
