OS X, particularly recent versions of the operating system, do a good job of corralling application windows by either not allowing a user to resize a window beyond the boundaries of the screen or by automatically snapping a window to a second display for those with multi-monitor setups.

Don’t squander precious time manually repositioning and resizing Mac windows over and over again. You can automate such drudgery to a large degree.

macOS offers some help. You’re probably aware of Split View, which puts two windows side-by-side in full-screen mode, and Apple has built in additional capabilities. Third-party utilities give you even more window control. There are many such apps out there, and even general-purpose utilities like Keyboard Maestro can help you move windows around.

One window-positioning utility, Magnet, is a zero-configuration tool that anticipates what presets users want. It was my favorite app of this kind for a long time. Last I checked, the $1.99 app sat atop the Mac App Store’s productivity category.

Another, Moom, lets you customize your window behavior. I weaned myself off Magnet and went all-in with Moom because of its flexibility. You can buy Moom for $10 directly from its developer, Many Tricks, or through the Mac App Store.

Magnet and Moom provide a capability I have envied in Microsoft Windows and Google’s ChromeOS: “window snapping.” When you drag windows to the edges of the screen, window snapping causes them to snap into particular positions and shapes.

More on Magnet and Moom in a bit—let’s look at what macOS can do for you first.

macOS Window Positioning Capabilities

Starting with macOS 10.11 El Capitan, Apple gave us Split View. Click a window’s green full-screen button at the upper left. As you hold the button, the window shrinks, and you can drag it to the left or right side of the screen. Release the button and then click a window on the other side of the screen to add it to Split View.

In 10.15 Catalina, Apple simplified the interface. Hover the pointer over a full-screen button and a menu appears with options to tile the window to the left or the right of the display. Choose one of those options, and macOS prompts you to select one of the remaining windows to fill the rest of the screen. That menu also provides an option to make a single window full-screen. That also happens if you tile one window but no additional windows are available to fill the remaining space.

Strangely, Apple’s help article about Split View makes no mention of a hidden feature in Catalina that gives you additional window-positioning options that don’t invoke full-screen mode.

Hover your pointer over the green button while pressing the Option key for a few seconds to see a different set of commands that let you move windows to the left or right instead of tiling them—meaning the windows are not taken full-screen but simply shifted to one half of the screen or the other.

While you’re Option-hovering, you also get a zoom button that causes a window to fill up the screen (minus the space occupied by the Dock and menu bar) without going full-screen. (In older versions of macOS, you can Option-click the full-screen button to maximize a window.)

I tip my hat to Scholle McFarland for including this information in her book, Take Control of Catalina, especially since so few others have noticed it.

Magnetize Your Screen Edges

Magnet gets you up and running quickly. Its menu bar presets include icons as well as text descriptors that make them instantly understandable. Magnet’s keyboard shortcuts strike me as difficult to memorize, but your brain might be up for the job.

Snap Windows On Mac

Regardless, you can resize Mac windows as left and right halves, as top and bottom halves, as quarter spaces, as one-third or two-thirds windows, and more, with results that never go full-screen. That’s usually my preference since it keeps the Dock and menu bar visible. If you have multiple displays, Magnet also offers Next Display and Previous Display commands to easily move windows from screen to screen.

For an easier approach, use Magnet’s mouse-based window positioning, which snaps windows into several positions and sizes:

  • Dragging a window to the display’s left or right edge triggers half-screen resizing.
  • Dragging a window to the top maximizes it (but does not take it full-screen).
  • Dragging to the corners of the screen triggers top-bottom halving or quartering, depending on precisely where you position the cursor. This takes a little practice.
  • Dragging to the bottom creates one-third or two-thirds windows, depending on exactly where you put the cursor. Again, practice makes perfect.

These dragging motions conjure up preview outlines of windows—as in Windows and ChromeOS—to guide you in achieving the desired positioning.

Tweak Moom to Your Liking

Power users seeking greater window-positioning superpowers should give Moom a look. You must be willing to tinker, though, since Moom offers only a few basic features until you customize it to your needs.

You can run Moom as a Dock or menu bar app, but the latter makes the most sense because it simplifies accessing your customized windows-positioning presets.

To get started, open Moom’s preferences and click Custom. You’ll find lots of options, but I suggest you start with Move and Zoom.


You’re presented with a grid that functions as a tiny facsimile of the screen. Drag your pointer across the grid to make a square or rectangle that corresponds to a hypothetical window’s onscreen shape and position. From then on, choose that preset from the Moom menu to position and size any window to those specs. If necessary for more precise positioning, you can tweak the grid’s horizontal and vertical cell density before creating presets.

I’ve used this feature to create presets that center windows with a variety of widths—narrower if I am browsing the Web and wider if I am working with others in a Google Doc and need enough room for team comments on the right side. I’ve also created presets that position windows that take up two-thirds of the left or right of my screen.

Mac Window Snapping App

You can also use Moom to reposition multiple windows at once. I often need a wider Google Chrome window to the left and a narrower one to the right. This was easy to set up. First, I manually positioned two Chrome windows exactly to my liking. Then, I chose the Save Window Layout Snapshot from the Moom menu. From then on, with two Chrome windows anywhere on the screen, I could instantly snap them into my preferred positioning. I also fashioned a preset for left and right Chrome windows of equal size.

Moom even supports scenarios that involve multiple apps. I often like to put a one-column Twitter client such as Tweetbot or Twitterrific on the left side of my display, with a Chrome window filling up the rest of the screen. Choosing Save Window Layout Snapshot saves this configuration in place. After that, when the Twitter client or Chrome is out of position, tidying them up is a cinch.

In addition, Moom takes over the green full-screen button in windows much the way Split View does in Catalina, but with more options in its hover menu. Hover the pointer over the full-screen button and you’ll see clickable icons for left and right halving, top and bottom halving, and maximizing.

Hold down the Option key while hovering and Moom presents you with quarter-window options. If you pine for Catalina’s default hover menu, press Command (or Command and then Option) as you hover, and its menu will appear.

Wait, there’s more! Moom offers a window “drawing” option via its hover menu. That means you can drag out a rectangle for on-the-fly resizing of your window in the proportions and positioning you want. You invoke this feature in one of two ways, depending on how you have configured Moom’s preferences:

  • In the hover menu, click the large icon that looks like a window outline (see image above). Moom displays a similar outline on your screen, and you can reposition and resize while holding down your mouse button. Release the mouse button when the outline is to your liking, and the window snaps to the rectangle you’ve drawn.
  • In the hover menu, you’ll see a hexagon-style grid. Drag your pointer across that grid to fill up any number of hexagons—the left half of the grid, the right two thirds, and so on. Moom reorients your window accordingly.

As a bonus, Moom includes window snapping via mouse dragging, but with fewer positioning options than Magnet provides. Moom provides only half-screen, quarter-screen, and maximize options.

Missing from Moom is a Magnet-style option to move windows from display to display with a keyboard shortcut.

Additional Utilities

I’ve focused on Magnet and Moom because they’re the window-resizing utilities I’ve used the most. Also, based on my research, I believe they offer the best mix of features for maximum versatility.

But I’d be remiss if I didn’t point you to a few other options.

  • Divvy ($13.99): If you just want grid-based window management à la Moom, Divvy is for you. Draw on a pop-up mini-grid to resize windows on the fly, or configure presets for standard configurations. (For those who use Windows as well as macOS, note that Divvy also exists for PCs.)
  • BetterSnapTool ($2.99): If you care mostly about window snapping, BetterSnapTool is the best choice I have seen that offers more granular control than Magnet and Moom. This app was also among the top-ranked paid apps in the Mac App Store’s productivity section last I checked.
  • BetterTouchTool ($6.50): Best known as a utility to turbocharge Apple trackpads and the Touch Bar on MacBook Pro laptops, BetterTouchTool provides window snapping, resizing, and moving controls. It’s also available via the $9.99-per-month Setapp app subscription service.
  • Rectangle. If free and open source is your jam, this Magnet-like utility might satisfy with features roughly comparable to Magnet. The publisher also offers the $7.99 Hookshot, which offers all of Rectangle’s features and adds additional window-snapping features.
  • Mosaic. If you use Setapp, you have nothing to lose by kicking the tires on Mosaic, but I found it a bit confusing.

Window Positioning Nirvana

Given the abundance of window-resizing utilities for macOS, there’s no reason to move and resize macOS windows manually all the time. If you find yourself constantly fiddling to get all your windows in just the right spot, macOS’s built-in controls or one of these utilities might be just the thing.

Some people will be satisfied with macOS’s native window-positioning features, which Apple improved in Catalina. If you want more, I recommend Moom because it offers a good mix of features along with a ton of customizability. For those with less inclination to tinker but who still wanting versatility, Magnet is a fantastic—and inexpensive—option.

Regardless, you have the tools at your fingertips to increase your Mac efficiency.

Moom: Bringing order to chaos since 2011

Moom makes window management as easy as clicking a mouse button—or using a keyboard shortcut, if you're one of those types of people.

With Moom, you can easily move and zoom windows to half screen, quarter screen, or fill the screen; set custom sizes and locations, and save layouts of opened windows for one-click positioning. Once you've tried Moom, you'll wonder how you used your Mac without it.

Pop-up positioning

Hover the mouse over any window's green button, and Moom's pop-up palette appears.

Quickly fill the screen, or move and resize to vertical or horizontal halves on screen edges. Want quarter-size windows instead? Hold down the Option key, and the palette presents four quarter-size corner options, along with 'center without resizing.'

Resizing isn't a drag…

Actually, it is a drag, using Moom's unique on-screen resizing grid.

Click in the empty box below the pop-up palette, move the mouse to where you'd like the window to be, then click-and-drag out its new dimensions.

Release the mouse button, and the window will fill the outline you've drawn on the screen.

…it's a snap!

Want to quickly move and zoom windows to certain areas of the screen? Just enable Moom's Snap to Edges and Corners feature.

Grab a window, drag it to an edge or corner, and release the mouse. You can set the resizing action for each location in Moom's preferences.

Save and restore window layouts

Set up a collection of windows in the size and locations you wish, then save the layout. Restore the layout via an assigned hot key or via Moom's menus.

This feature is particularly useful if you use a laptop with an external display—Moom can trigger saved layouts on addition or removal of displays.

No mouse required

Don't worry, keyboard users—Moom isn't just for those who prefer using a mouse. Enable keyboard control, and you can move, resize, center, use the on-screen grid, and much more—all without touching the mouse.

In addition, every custom Moom command—keep reading!—can be assigned a global keyboard shortcut, or one that works only when the keyboard controller is onscreen.

Window Snapping Mac Os

Countless custom commands

Create and save often-used Moom actions to a menu of custom commands—complete with optional dividers and labels.

Moving, zooming, resizing, centering, even moving to other displays—all are doable via custom commands. You can even create a sequence of commands tied to one shortcut, easing complex move and sizing operations.

But wait, there's more!

Windows Snapping App

  • Use Moom as a normal Dock-based app, as an icon in the menu bar, or as a completely invisible background app.
  • Access custom commands through the Moom menu bar icon, through the green button's pop-up palette, or via keyboard shortcuts.
  • Use a small hexagonal grid for grid resizing, instead of the full-screen virtual grid.
  • Move windows across displays—and with chained commands, zoom them to new sizes and locations while moving.
  • Display a keyboard cheat sheet that shows what tasks you've assigned to which keys in keyboard mode.
  • Resize windows to precise dimensions—perfect for checking how well things fit in windows of varying sizes.
