When you are deeply involved in a complex project on your Mac, it is incredibly easy to accidentally open 15 different Finder windows. When you finally finish the task, manually clicking the tiny red “X” button in the corner of every single window to clean up your desktop is tedious and time-consuming. Instead of closing them one by one, you can use a hidden keyboard shortcut to instantly nuke every single open Finder window simultaneously.
The Magic of the Option Key
In macOS, the Option (⌥) key is the gateway to hundreds of hidden “alternate” functions. Whenever you hold down the Option key, standard menus and buttons instantly transform, changing their behavior to apply system-wide commands.
This rule perfectly applies to the standard window-closing mechanics.
How to Close All Windows Instantly
To execute the mass-close command, follow this precise sequence:
- Ensure that Finder is your currently active application. (You can confirm this by looking at the top-left corner of your menu bar; it should say “Finder” in bold letters next to the Apple logo. If it doesn’t, simply click anywhere on your empty desktop background).
- Locate any single open Finder window on your screen.
- Press and hold the Option (⌥) key on your keyboard. Do not let go.
- While firmly holding the Option key, use your mouse to click the tiny red Close button in the top-left corner of that specific Finder window.
The exact millisecond you click that single red dot, macOS will intercept the command, realize the Option key is engaged, and instantly vaporize every single open Finder window across your entire desktop, regardless of how many you had open.
The Keyboard Shortcut Alternative
If you prefer to keep your hands on the keyboard and avoid the mouse entirely, the standard shortcut to close a single window is Command (⌘) + W.
By applying the exact same Option key logic, you can execute the mass-close command entirely from the keyboard.
Simply press Command (⌘) + Option (⌥) + W simultaneously. Every open Finder window will immediately vanish, instantly returning you to a perfectly clean desktop.
