Window Management on Mac: There’s No Snap, Here’s What to Use Instead
If there’s one Windows feature switchers consistently ask about, it’s Snap — Win+Left/Win+Right to instantly dock a window to half the screen, or the fancier Snap Layouts grid in Windows 11. macOS handled window management very differently for a long time, though that’s genuinely changed recently.
The good news: it’s finally native
As of macOS Sequoia (2024), Apple added real window tiling. Drag a window to the edge of the screen and it snaps to fill half — the same core gesture as Windows Snap. There’s also a Window menu (in most apps’ menu bar) with explicit “Move to Left/Right Half” options, and keyboard shortcuts you can set for them in System Settings > Keyboard > Keyboard Shortcuts.
If you’re on an older macOS version (Ventura, Sonoma, or earlier), this doesn’t exist — window tiling was one of the more requested features for years, and third-party tools filled the gap. If you’re not sure which you’re on: Apple menu > About This Mac tells you.
If you’re on an older macOS: Rectangle is the answer
Rectangle is a free, open-source app that adds Windows-style Snap behavior — keyboard shortcuts to move a window to any half, quarter, or corner of the screen, plus drag-to-edge snapping. It’s the single most commonly recommended tool for this exact gap, and it’s been the de facto standard for years. Install it, grant it Accessibility permissions when prompted (it needs this to move windows programmatically), and its default shortcuts will feel immediately familiar if you’re used to Snap.
Magnet is a similar paid alternative from the App Store, if you’d rather not grant an app the Accessibility permissions Rectangle needs, or prefer App Store distribution.
The tools Mac has always had, that aren’t quite the same thing
Full-screen mode (green button, top-left of most windows, or ⌃+⌘+F) — dedicates an entire display to one app, with its own virtual desktop (Space). Not the same as tiling; more like Windows’ maximize, but it also creates a swipeable desktop for that app specifically.
Split View — hold the green button and choose “Tile Window to Left/Right of Screen” from the menu that appears, then pick a second app to fill the other half. This predates Sequoia’s drag-to-snap and still works identically on any recent macOS version — it’s just a couple more clicks than a direct drag.
Mission Control (F3, or three-finger swipe up) — not window tiling exactly, but the fastest way to see every open window across every Space at once and click the one you want. Genuinely useful once you have more than 4–5 windows open and can’t find one by ⌘+\` alone.
Multiple desktops (Spaces) as an alternative to tiling
Rather than splitting a screen between two apps, macOS also supports assigning apps to their own full-screen Spaces (virtual desktops) and swiping between them with a three-finger swipe left/right. It’s a genuinely different workflow than side-by-side tiling — some people find it faster once they’re used to it, since each Space is a distraction-free full screen — but it’s not a direct substitute if what you actually want is to see two windows simultaneously.
The practical recommendation
If you’re on Sequoia or later: the built-in tiling covers most of what Snap did, and you don’t need a third-party tool. If you’re on an older macOS or find the built-in behavior too limited (no snap zones for thirds of the screen, for instance), Rectangle is free, well-maintained, and the standard recommendation across almost every “switching to Mac” community thread for exactly this reason.
