Everything you need to tame your windows

Snap Assist

Snap one window. Get offered the rest.

Dock a window and your other windows appear in the empty space. One click each fills the screen.

Windows 11 Snap Assist, on your Mac. Nothing moves until you click. Esc dismisses it.

Dock previews

Hover the Dock. See every window.

Rest on a Dock icon to see live thumbnails of that app's windows. Click one to jump straight to it.

Taskbar previews, Mac edition. Minimized windows and windows on another desktop show too, with a badge saying where they are.

Hold to snap

Hold a title bar. A snap menu appears.

Click and hold any window's title bar, sweep onto a zone, release. The window glides there.

Wheel or Gallery style, your pick in Settings. Targets are forgiving, so you never need to be pixel-perfect.

Per-display memory

Unplug a monitor. Plug it back. Everything returns.

WonderSnap remembers how your windows sit on each monitor setup and puts them back the moment it reconnects.

Automatic, nothing to save. Your Mac piles everything onto one screen and never puts it back. Now it does.

Parked windows

Unplug to move desks. Your windows wait.

A disconnected monitor's windows park in the Dock as a group, still arranged, instead of piling onto the screen you have left.

Bring them back or send them home. Show them on this screen, park them again, or plug the monitor in and they return, laid out as you left them. P shows or re-parks everything.

Off until you switch it on, because it minimises windows for you.

Your remaining screen keeps its own layout. Nothing is piled on top of it.

Display controls

Your monitor's brightness. In the menu bar.

Brightness, contrast, volume, colour and input for your external monitor, from the WonderSnap menu. No buttons behind the screen.

Set it once, it comes back. Whatever you set is remembered per display and put back when that monitor reconnects.

Brightness & contrast Switch input Settings remembered per display

External monitors need an Apple Silicon Mac and DDC/CI over USB-C or Thunderbolt. The built-in screen gets brightness too. Apple's Studio Display and Pro Display XDR are not supported. WonderSnap tells you, per display, whether it can control it.

Hold and tap: arrows for halves, U I J K for corners, D F G for thirds. Tap again to cycle ½ → ⅔ → ⅓.

Same keys as Rectangle and Magnet, so your muscle memory carries over. Every shortcut is rebindable in Settings.

Switching from Windows?

Windows 11-style window management, on your Mac

Your snapping muscle memory still works. If you moved to a Mac and immediately missed Win + arrow, Snap Layouts, and Snap Assist, WonderSnap is the missing piece. Every habit has a home here.

Win + Arrow → ⌃⌥ + key

Two-key chords snap to halves, corners and thirds. Tap again to cycle sizes.

Snap Layouts → the picker

Hold any title bar or press ⌃⌥Space. Design your own layouts too, like FancyZones.

Snap Assist → built in

Dock one window and the rest are offered for the remaining space. No other Mac app has it.

Taskbar previews → the Dock

Hover a Dock icon and see every window live. Click one to jump to it.

Why people switch

Rectangle and Magnet nail the basics: halves, quarters, thirds. WonderSnap does all of that too, then adds the power features neither of them has.

Questions, answered

Everything you might want to know before you download.

How do I get Windows 11-like window management on a Mac?

Install WonderSnap (often searched as "Wonder Snap"). It brings the full Windows 11 window management experience to your Mac: Snap Layouts via the ⌃⌥Space picker, Snap Assist that offers your other windows for the remaining space, and Win + Arrow-style keyboard snapping on ⌃⌥ chords. Unlike a full tiling window manager, it keeps macOS feeling like macOS: windows only move when you ask.

Which macOS versions does it support?

WonderSnap runs on macOS 14 (Sonoma) and later, on both Apple Silicon and Intel Macs. It's a native, lightweight menu-bar app, with no background bloat.

Why does it need Accessibility permission?

Moving and resizing other apps' windows on a Mac requires the system Accessibility permission. WonderSnap uses it purely to position windows. Nothing is recorded or sent anywhere. A guided onboarding flow walks you through granting it in one tap.

Is there a free trial?

Yes, and the direct download is the trial. You get 7 days of the full app, every feature unlocked, starting the first time you launch it. No account, no credit card. When the trial ends, WonderSnap locks until you enter a license key.

How much does it cost?

Two options, and both unlock the same app with every feature included. A 1-year license is $2: no subscription and no auto-renewal, so when the year ends you simply buy a new key if you want to carry on. A lifetime license is $8, paid once, with free updates forever. No tiers, everything included, no catch. Your license key arrives by email right after checkout through Dodo Payments, and you activate it inside the app under Enter License.

How is this different from macOS's built-in tiling?

The native tiling covers casual halves and quarters. WonderSnap adds the power features: a hold-to-snap menu on every title bar, Snap Assist that fills the rest of the screen, a Snap Layouts picker, custom layouts, thirds, saved arrangements you can recall instantly, adjustable gaps, smooth animations, and per-display memory that restores your setup when a monitor reconnects.

Is WonderSnap a good Magnet or Rectangle alternative?

Yes. WonderSnap covers everything Magnet and Rectangle do: halves, quarters, thirds, corners, and keyboard shortcuts for every position. On top of that it adds the Windows 11 features neither has: Snap Assist, a visual Snap Layouts picker, a hold-to-snap menu on every title bar, custom layouts, and per-display memory. It costs $2 for a year or $8 for life, with every feature included in both.

Can WonderSnap restore my windows when I reconnect an external monitor?

Yes, automatically. Your Mac piles every window onto the built-in screen when a monitor disconnects and never puts them back. WonderSnap remembers the arrangement for each display setup, and the moment your monitor reconnects, every window returns to exactly where it was. No clicks needed.

What happens to my windows when I unplug a monitor?

By default your Mac moves them onto the screen you still have, on top of whatever was already there. WonderSnap can park them in the Dock as a group instead, still arranged, and send them home to that monitor when you plug it back in. Show them on your remaining screen at any time from the Parked Windows menu, or with Control Option P. It is off until you switch it on, because it minimises windows on your behalf.

Can WonderSnap change my monitor's brightness and contrast?

Yes, from the Displays section of the WonderSnap menu: brightness, contrast, sharpness, volume and mute, colour temperature and colour preset, red, green and blue gain, and which input the monitor is showing. Whatever you set is remembered for that display and put back when it reconnects. It talks to the monitor over DDC/CI, the same channel its own buttons use, so external monitors need an Apple Silicon Mac and a connection over USB-C or Thunderbolt. HDMI works on many Macs but not all. The built-in laptop screen gets a brightness control too, over the Mac's own mechanism rather than DDC/CI. Apple's own external displays, the Studio Display and Pro Display XDR, are not supported. WonderSnap checks each display when you connect it and tells you which ones it can control.

Is there a FancyZones equivalent for Mac in WonderSnap?

Yes. The custom layout editor is WonderSnap's FancyZones: drag dividers to design any grid you want, spanning all of your displays, then fill it from the layout picker or let Snap Assist fill it for you. Because zones are carved from splits, layouts never have gaps or overlaps.

Can I see window previews from the Dock, like the Windows taskbar?

Yes. Rest your pointer on any running app's Dock icon and WonderSnap shows thumbnails of that app's windows. Click one to jump straight to it, exactly like hovering the taskbar on Windows 11. Live thumbnails use the Mac's optional Screen Recording permission; without it you still get the panel with app icons and window titles. Minimized windows and windows on another desktop show a thumbnail too, with a badge saying where they are, and clicking one brings it back.

Does it fight macOS's own drag-to-edge tiling?

No, by design. Dragging a window to a screen edge stays 100% native macOS behavior; WonderSnap never intercepts it. WonderSnap's gestures live elsewhere: hold a title bar for the snap menu, use the ⌃⌥ chords, or open the ⌃⌥Space picker. The two coexist cleanly.

Does it work with multiple monitors?

That's where it shines. Custom layouts span all your displays, and per-display memory remembers a distinct arrangement for each monitor combination, so undocking and redocking your laptop just works.

Will it fight with Chrome or Electron apps?

No. WonderSnap includes specific workarounds for Chromium-based apps (Chrome, Brave, Electron) whose windows are notoriously tricky to move, so they snap cleanly like everything else.

Stop dragging. Start snapping.
