One of the biggest challenges with modern computing is managing dozens of open windows. Do you minimize apps to the Dock? Let them pile up? Spend minutes clicking between them? macOS offers elegant solutions through Split View and Stage Manager. After helping clients organize their chaotic screens, I've seen these tools transform productivity. Let me show you how to master window management on your Mac.
Split View: Side-by-Side Windows
Split View lets you fill your screen with two windows side-by-side, each taking exactly half the display. This is perfect for comparing documents, watching a video while working, or following a tutorial while you code.
Entering Split View
There are several ways to enter Split View:
Method 1: Green Button
- Hover over the green traffic light button in any window's title bar
- Hold Option (⌥) on your keyboard
- Click the green button
- The window expands to fill half the screen
- Select another window to fill the other half
Method 2: Full Screen with Options
- Hold Option+Shift while clicking the green button
- Window fills exactly half the screen (instead of full screen)
- Select another window for the other half
Method 3: Drag to Edge
- Drag a window by its title bar
- Move it to the left or right edge of the screen
- A translucent overlay appears showing the Split View zone
- Release to snap the window to that half
Exiting Split View
To exit Split View:
- Move cursor to the top of the screen to reveal the title bar
- Click the green button
- Or press Escape (though this doesn't always work)
- Drag the window divider away from the edge
Split View Limitations
Split View has some constraints:
- Only two windows can be in Split View at once per display
- You can't resize the split (it's always 50/50)
- The Split View apps take full focus—no other windows visible until you exit
- Works best with full-screen apps disabled in System Settings
Stage Manager: The Modern Approach (macOS Ventura+)
Stage Manager, introduced in macOS Ventura, offers a new approach to window management. It automatically organizes windows on the left side of the screen, keeping the current app prominent and others accessible but not in the way.
Enabling Stage Manager
- Open System Settings > Desktop & Dock
- Find "Stage Manager" in the right panel
- Toggle Stage Manager ON
- Optionally click "Customize" to adjust behavior
Stage Manager Features
When Stage Manager is enabled:
- Your active window appears centered and prominent
- Other open windows stack to the left in a compact view
- Click any window in the stack to bring it to focus
- Windows automatically organize as you open new apps
- The desktop remains accessible behind the windows
Customizing Stage Manager
In System Settings > Desktop & Dock > Stage Manager customization:
- Show items from other spaces: Include windows from other Spaces in the Stage Manager stack
- Group windows by application: Stack windows from the same app together
- Keep arranged: Maintain the Stage Manager arrangement even when you close apps
Split View vs. Stage Manager
Which should you use? Here's my assessment:
| Feature | Split View | Stage Manager |
|---|---|---|
| Window count | 2 windows only | Multiple windows |
| Resizing | Fixed 50/50 | Flexible |
| Focus | Both windows visible | One window prominent |
| Learning curve | Simple | New concept |
| macOS version | OS X El Capitan+ | Ventura+ only |

Practical Workflows
Here are real-world window management workflows I teach clients:
Document Reference
When writing a report and needing to reference another document:
- Open both documents
- Use Split View to view side by side
- Or use Stage Manager and click between windows
Video + Work
Watching a tutorial while working:
- Put video player in one half of Split View
- Put your work app in other half
- Watch and follow along without switching
Code + Output
Development workflow:
- IDE/code editor in one window
- Browser or terminal in another
- Reference documentation alongside code
Email While Working
Keep email visible without full Split View:
- Use Stage Manager—email stays in accessible stack
- Or float email window and manually position
- Option+click elsewhere to return focus to work
Full Screen Apps vs. Split View
macOS offers full screen mode as well. Here's when to use each:
Use Split View When:
- You need two apps visible simultaneously
- Working on one task with reference materials
- Comparing two documents
- Following a video tutorial while practicing
Use Full Screen When:
- You need maximum focus on one app
- You're on a small screen (like MacBook)
- You want to eliminate all distractions
- You're using Stage Manager on a larger display
Use Stage Manager When:
- You have many windows open
- You want flexible focus vs. context switching
- You're on macOS Ventura or later
- You prefer automatic organization over manual arrangement
My Window Management Setup
Here's my actual daily configuration:
Primary Setup
- Stage Manager enabled on my primary MacBook Pro
- Magnet installed for keyboard-driven tiling when needed
- Split View for dedicated two-app focus sessions
Typical Day
- Start with Stage Manager managing 5-8 open windows
- When needing focused work, use Magnet to tile two apps
- When comparing, use Split View for perfect alignment
- Close apps I'm done with to reduce clutter
Troubleshooting Window Management
Common issues and solutions:
Split View Not Available
If Split View doesn't work:
- Ensure the app supports Split View (not all apps do)
- Check System Settings > Desktop & Dock > Requires at least full screen apps is OFF
- Try closing all apps and starting fresh
Stage Manager Disappearing
If Stage Manager turns off unexpectedly:
- Check System Settings for accidental toggle
- Some apps can interfere—quit non-essential apps
- Restart your Mac if issues persist
Windows Not Snapping
If windows don't snap properly:
- Ensure you're dragging to screen edge (not just anywhere)
- Check that no other window is blocking the snap zone
- Restart Dock (Terminal: killall Dock)
Conclusion
macOS offers powerful window management through Split View, Stage Manager, and keyboard shortcuts. No matter how you prefer to work—focused on one app, juggling several, or somewhere in between—there's a window management approach that fits your style.
Start with the basics: try Split View this week when you need to reference two things. If you find yourself managing many windows, give Stage Manager a chance. Power users should consider Magnet. The investment in learning these tools pays dividends in daily productivity.
