Paneway — Window Snapping and Layouts for Mac

Paneway puts every window where it belongs. Snap the window in front to halves, quarters or thirds with a keyboard shortcut, by dragging it to an edge of the screen, or by clicking a layout in the menu bar. Everything happens on the Mac, with no account and no internet connection.

Drag it to an edge

Push a window against the left or right edge and a glass outline shows the half it will fill. A corner gives a quarter and the top edge maximises. Let go while the outline is showing and the window snaps into place. Edge margin sets how close the pointer must be, from 1 to 40 pt.

One click, one layout

The menu bar panel shows a small picture for every layout, grouped as Halves, Quarters, Thirds, Window and Displays. Click one and the window in front goes straight there. The panel does not take focus, so the app you were working in stays in front. Hover a picture to see its name and shortcut.

Every layout on a key

Nineteen Control-Option shortcuts cover halves, quarters, thirds, two thirds, maximise, almost maximise, centre, restore and moving to the next or previous display. Each one can be switched off, and any combination another app already owns is marked In use elsewhere.

Put everything back

Workspaces save where every visible window of every open app sits. Press Restore and the windows go back, matched by app and title first, then in order. Apps that are closed are skipped until they are opened again.

Room to breathe

Gap between windows adds 0 to 20 pt around and between windows, and neighbouring windows always end up exactly one gap apart. Every layout stays clear of the menu bar and the Dock, and each display is handled separately, whatever its size.

How to snap windows on a Mac

macOS 15 Sequoia and later can tile windows on their own: drag a window to the edge of the screen, or choose Window, then Move & Resize, in the menu bar. Stage Manager groups windows instead of placing them side by side.

Paneway goes further and also runs on macOS 13 and 14: halves, quarters and thirds, each on its own keyboard shortcut, adjustable gaps between windows, one-click layouts in the menu bar, and workspaces that save and restore where every window sits.

How it works

• Press a shortcut. Every one uses Control-Option and acts on the window in front: arrows for halves, U I J K for quarters, D F G for thirds, E and T for two thirds, Return to maximise, M to almost maximise, C to centre and Delete to restore.
• Or drag it. Push a window against a screen edge or into a corner, and a glass outline shows where it will land. The top edge maximises. Let go to snap, or move away to cancel.
• Or click a layout. The menu bar icon opens a panel of small pictures. Click one and the window in front goes there, while the app you were using stays in front.
• Send it to another display with Control-Option-] or Control-Option-[. A window in a layout keeps that layout on the other screen.
• Save a workspace to record where every visible window sits, and press Restore later to put them all back.

Opening it the first time

Paneway is signed and notarized by Apple, so it opens with a normal double-click. Paneway then needs the Accessibility permission, because macOS only lets an app move another app's windows with it: press Grant Accessibility in the panel and switch Paneway on in the list.

Why does it need Accessibility?

macOS only allows one app to read and change another app's window positions and sizes through the Accessibility permission. Paneway uses it for that alone, and never switches it on by itself.

Does it send anything anywhere?

No. There is no account and no internet connection. Shortcuts, settings and saved workspaces stay on the Mac.

Why does a window sometimes land a little short?

Some apps only resize in steps, such as Terminal, which rounds to whole lines, and some have a minimum size. Paneway sets the exact frame and the app decides the rest. Full-screen windows are their own space in macOS and cannot be moved until they leave full screen.

Does it work with more than one display?

Yes. Control-Option-] and Control-Option-[ move a window to the next or previous display, keeping its layout. Drag to snap works on outer edges; where two screens meet, the pointer passes to the next screen instead of stopping, so a shortcut is the way there.

Which Macs does it run on?

Any Mac with Apple silicon or Intel running macOS 13 Ventura or later.

Is Paneway different from the window tiling built into macOS?

The built-in tiling covers halves and quarters by dragging or through the Window menu. Paneway adds thirds and two-thirds, a shortcut for every layout, gaps between windows, moving a window to another display with a key, and saved workspaces, and it runs on macOS 13 and 14 as well.
