Best Window Management & Multi-Monitor Apps for Mac (2026)

If you've ever spent five minutes dragging windows around to get a browser on the left and notes on the right, or plugged your MacBook into a second monitor and watched every window pile up on one screen, you know macOS window management has limits.

The good news is that Apple has improved things. Since macOS Sequoia 15, macOS has had built-in window tiling. But power users, multi-monitor setups and anyone who repeats the same layout every day still benefit from a dedicated app.

This guide covers macOS's built-in tools first, then compares the best window managers and multi-monitor utilities: Moom, Rectangle, Rectangle Pro, extraDock and DisplayBuddy.

Quick Picks

Best free window manager: Rectangle. It's open source, with keyboard shortcuts and snap areas.

  • Best for saved layouts and flexibility: Moom, for a $15 one-time price.

  • Best for gestures and multi-Mac sync: Rectangle Pro

  • Best for multi-monitor docks: extraDock, which gives you a separate Dock on every screen.

  • Best for external monitor control: DisplayBuddy, for brightness, input and volume via DDC/CI.

  • No app needed: macOS's built-in tiling covers basic halves and quarters.

Built-In Window Management in macOS

Before installing anything, try what's already built into macOS Sequoia 15, Tahoe 26 and Golden Gate 27.

Tile Windows by Dragging

Drag a window to the left or right edge of the screen to fill that half, or to a corner to fill a quarter. Drag it to the menu bar to fill the screen.

Use the Green Button

Hover the pointer over a window's green button (top-left). A menu appears with tiling layouts. Pick one to move and resize the window instantly.

Change Tiling Settings

Open System Settings → Desktop & Dock → Windows to adjust tiling behaviour. For example, you can turn edge-dragging on or off, or choose whether tiled windows have margins.

Other Built-In Tools

  • Split View: two apps side by side in full screen

  • Stage Manager: groups app windows into sets on the side of the screen

  • Mission Control and Spaces: multiple virtual desktops (see below)

Where Built-In Tiling Falls Short

  • No saved layouts for your whole workspace

  • Few custom sizes, such as thirds or two-thirds

  • No automatic layout changes when you connect or disconnect a monitor

  • Limited per-display control

Best Window Manager Apps for Mac

2. Rectangle Pro: Best for Gestures and Advanced Layouts

3. Moom: Best for Saved Layouts and Customization

Moom by Many Tricks has been a favourite Mac window manager for over a decade. The current Moom 4 is its most flexible version yet.

Key features

  • Pop-up palette: hover over a window's green (or red or yellow) button to get a palette of up to 61 custom actions

  • Saved layouts: save the positions of windows in specific apps, and restore them with one click. This is ideal when you plug a MacBook into an external display.

  • "Any window" layouts: apply a layout to your most recently used windows, whatever the app

  • Snap zones and drop zones: drag a window to a screen edge, then drop it into a precise position

  • Chains: combine actions, such as moving a window to another display and resizing it in one step, or cycling through actions

  • Hover: move and resize windows by holding modifier keys and moving the mouse, with no clicking or dragging edges

  • Keyboard control: move, resize and use an on-screen grid without touching the mouse

  • Folders of actions, plus import/export to share setups

Is Moom available for Windows? No. Moom is a Mac-only app.

Best for: Users who work with the same set of apps every day and want one-click layouts, especially on a laptop that moves between desk and travel.

Best Multi-Monitor Apps for Mac

4. extraDock: A Separate Dock on Every Screen

On macOS, the Dock appears on one screen at a time. It moves to another display when you push the pointer to the bottom edge there, which can be frustrating on a multi-monitor desk. extraDock by Appit Studio solves this.

Key features

  • Create unlimited custom floating docks, each with its own apps, folders and widgets

  • Pin docks to specific monitors. They hide when that monitor disconnects and come back when it reconnects.

  • Visual customization for size, opacity, blur, border and colour

  • Widgets, including spacers and a Live Dock widget that mirrors the native macOS Dock

  • Drag files onto dock folders

  • Auto-hide in full-screen apps

  • Snap to screen edges or float anywhere

  • Installable via Homebrew

Example setup:

  • Center monitor: a development dock with your code editor, Terminal and Git client

  • Left monitor: a communication dock with Mail, Slack and Messages

  • Right monitor: a design dock with Figma, Photoshop and Pixelmator

Best for: Mac mini, Mac Studio and MacBook users with two or three displays who want the right apps on every screen.

5. DisplayBuddy: Control External Monitors From Your Mac

Most external monitors force you to use awkward physical buttons to change brightness or input. DisplayBuddy controls them from the Mac menu bar using the DDC/CI protocol.

Key features

  • Brightness, contrast and volume sliders for compatible external monitors

  • Presets: save a full display setup, including resolution, rotation, input, brightness, HDR, Night Shift and arrangement, then restore it with one click

  • Schedules: activate presets at sunrise and sunset, at set times, when a charger is connected, or with Dark Mode

  • Samsung Smart Monitor and LG MyView control over Wi-Fi

  • Shortcuts, Spotlight and Siri integration, plus a command-line tool

License: Sold as a lifetime license. Check the developer's site for current requirements and pricing.

Best for: Anyone with external monitors who's tired of fiddly monitor buttons.

Spaces: Virtual Desktops on Mac

Spaces are macOS's built-in virtual desktops. They're great for separating work, personal and project windows.

How to Use Spaces

  • Open Mission Control: swipe up with three or four fingers, or press F3 or Control-Up Arrow

  • Add a Space: click + in the top-right corner of Mission Control

  • Switch Spaces: swipe left or right with three or four fingers, or press Control-Left/Right Arrow

  • Assign an app to a Space: right-click its Dock icon → Options → Assign To

Multi-Monitor Tip

In System Settings → Desktop & Dock → Mission Control, the "Displays have separate Spaces" option lets each monitor switch Spaces independently. Turn it off if you want all screens to switch together.

Spaces Apps

macOS doesn't show the Space number or name in the menu bar, and you can't arrange Spaces in a grid. Third-party apps such as Spaceman (Space indicators) and TotalSpaces (grid layouts) have been popular for filling these gaps. Check each developer's site for current macOS compatibility before installing, since utilities that modify Spaces often need updates after major macOS releases.

Best Setup by Mac User Type

MacBook Air or Pro Users (Laptop Only)

Built-in tiling may be enough. Add Rectangle for thirds and quicker shortcuts.

MacBook + External Monitor (Desk and Travel)

Moom or Rectangle Pro, so your saved layouts restore when you plug in. Add DisplayBuddy to control the monitor.

Mac mini / Mac Studio With 2–3 Monitors

extraDock for a Dock on each screen, Moom or Rectangle Pro for layouts, and DisplayBuddy for brightness and input switching.

Developers

Rectangle or Rectangle Pro for keyboard-first workflows, combined with Spaces for each project. Pair them with a launcher from our Alfred vs Raycast guide. Raycast includes basic window management too.

Designers and Video Editors

Moom saved layouts for tools and preview windows, plus DisplayBuddy presets for colour-critical work.

Troubleshooting

"Keyboard shortcuts don't work."
Check that the app has Accessibility permission, and look for conflicts with macOS's own tiling shortcuts (Fn-Control-arrows) or other apps.

"Windows jump when I drag them to the edge."
Both macOS tiling and a third-party app may be active at once. Turn off edge-dragging in System Settings → Desktop & Dock, or disable snap areas in the third-party app.

"My layout breaks when I connect a monitor."
Use Moom's layouts (which adapt to display sizes) or Rectangle Pro's display triggers. Also check that the monitor arrangement in System Settings → Displays hasn't changed.

"The Dock keeps jumping to my other monitor."
That's normal macOS behaviour when you move the pointer to the bottom edge of a screen. Use extraDOCK for a fixed Dock on each screen.

"External monitor brightness can't be changed."
Your monitor may not support DDC/CI, or it may be disabled in the monitor's own menu. Some USB-C hubs and docks also block DDC/CI signals.
