Window Management Basics
Managing windows on macOS differs slightly from other operating systems. Understanding the basic controls and snapping features will greatly improve your workflow.
The Traffic Lights
Located in the top-left corner of every window are three colored buttons:
1. Close (Red)
- Action: Closes the window.
- Note: For most document-based apps (like Word or Pages), closing the window does not quit the application. The app remains running in the Dock (indicated by a small dot). To quit fully, press Command + Q.
2. Minimize (Yellow)
- Action: Swooshes the window down into the right side of the Dock.
- Restore: Click the window's icon in the Dock to bring it back.
3. Full Screen (Green)
- Click: Enters Full Screen mode, hiding the Menu Bar and Dock for an immersive experience. Move your mouse to the top of the screen to reveal the Menu Bar.
- Option + Click: If you hold the Option key, the Green button changes to Zoom (+). Clicking this expands the window to fit the content or the screen without entering Full Screen mode.
Window Snapping
While macOS does not have "drag-to-edge" snapping enabled by default like Windows, it has a built-in tiling feature.
- Hover your mouse over the Green full-screen button (do not click).
- A menu will appear with options:
- Tile Window to Left of Screen
- Tile Window to Right of Screen
- Select one, and the window will fill that half of the screen. You can then select another open window to fill the other half (Split View).
Mission Control
Mission Control offers a bird's-eye view of all your open windows and desktops.
- Activate: Swipe up with three (or four) fingers on the trackpad, or press the F3 key (Mission Control icon).
- Usage: You can drag windows to different "Spaces" (Desktops) at the top of the screen to organize your work (e.g., one desktop for Email, one for Coding).
App Exposé
To see all open windows for just the current application (e.g., all 5 open Word docs):
- Activate: Swipe down with three (or four) fingers on the trackpad.
