The whole screen: one ⌥⌘A puts four windows (Safari, Calendar, Notes and Preview) into a 2 × 2 gridShortcuts
Never leave the keyboard
Halves, corners, thirds and the next display are each one shortcut away. Press the same key again to cycle 1/2 → 3/4 → 1/4, and hold ⌥⌘ for a second to see every shortcut.
Pressing ⌥⌘← again and again resizes the window to 1/2 → 3/4 → 1/4 of the screen
Auto arrange
Up to nine windows with one ⌥⌘A
⌥⌘A arranges the windows on the display with the front window to fit how many there are. You can also pick a display and a shape in the menu's Layout section. One ⌥⌘Z puts every window back.
Displays
Unplug and replug without losing your place
When you unplug a display, its windows move to the screens that are left. Plug it back in and they return. A display Split hasn't seen before gets an automatic layout.
Saved layouts
Save and restore layouts
Save every window's place across all displays under a name. Split can load it automatically when the same displays connect. Free for everyone.
Effects
See where it went
The moved window glows briefly and the shortcut you pressed appears on screen. Change strength, color and duration in Settings › Effects, or turn them off.
Setup
One switch and you're ready
On first launch Split opens the Accessibility page in System Settings. Turn on the switch next to Split and the guide changes to "You're all set" and shows the first shortcut to try. If it still doesn't work, click "It's on but not working" in the guide. Windows and Linux skip this step.
Shortcuts
All shortcuts
These are the keys after a fresh install. Change any of them in Settings › Shortcuts. On Windows press Win instead of ⌘, Alt instead of ⌥ and Ctrl instead of ⌃; on Linux press Super instead of ⌘.

Install
Install in three steps
Runs on macOS 13 or later (Apple silicon and Intel), 64-bit Windows, and Linux in an X11 session.
- 1
Download and move
Open the dmg and drag Split to Applications. It's notarized by Apple, so you won't see an "unidentified developer" warning.
- 2
Flip the permission switch
On first launch System Settings opens by itself. Turn on the switch next to Split in the list, and the guide changes to show the first shortcut to try.
- 3
Try it
The Split icon appears in the menu bar. Press ⌥⌘← to send the current window to the left half.
Install with Homebrew
Paste all three lines into Terminal. Recent Homebrew asks once before using a repository outside its official list, so the second line is there.
brew tap runners-im/tap
brew trust runners-im/tap
brew install --cask splitPrivacy
Window positions stay on this Mac
What it reads
The position and size of other apps' windows, through macOS Accessibility, so it can move them. Saved layouts write app names, window titles and positions to a file on this Mac only.
What it sends
Nothing unless you sign in on the Phone tab. Once you do, it sends the computer name, display info and the names of saved layouts to the RUNNERS server so the phone app can recognize this computer. No ads, no usage stats.
Where it connects
It reads the update list on GitHub (once a day, can be turned off). Only when you sign in on the Phone tab does it connect to the RUNNERS server (server.system.runners.im).
Pricing
Free to use. Pro when you need it.

Split Pro PRO
$1/ month
or $6 / year (50% off)
We're still deciding which new features Pro will add.
We're getting payments and RUNNERS accounts ready. Once they open, you can start Pro right here.
FAQ
Will free features become paid later?
No. Everything that is free today stays free. Pro only adds new features that don't exist yet.
When can I get Pro?
It isn't on sale yet. We're getting RUNNERS accounts and payments ready; once they open, you can start right from the pricing section on this page. Each app costs $1 a month or $6 a year.
How do I install it?
Download the dmg from this page and drag Split to Applications. With Homebrew, paste the three lines from the install section into Terminal.
Homebrew says it can't trust the tap
Recent Homebrew asks once before using a repository outside its official list. Run brew trust runners-im/tap, then install again.
Does it run on Apple silicon and Intel?
Yes. One app runs natively on both chips. It needs macOS 13 Ventura or later.
Why does it need Accessibility access?
On macOS, apps can only move other apps' windows with this permission. Turn Split on under System Settings › Privacy & Security › Accessibility. Windows and Linux have no such permission.
I turned it on but windows don't move
An old permission entry left over from an update can get in the way. Click "It's on but not working" in the permission guide; Split registers itself again and opens Settings. Turn the switch back on there.
A shortcut clashes with another app
Change it in Settings › Shortcuts, or press × to clear it. To pause shortcuts for a while, use Pause Shortcuts in the menu for an hour or while that app is in front.
Shortcuts don't work in some apps
On a Mac, shortcuts turn off by themselves while Photoshop or Steam is in front. If they don't work in another app, check the status line at the top of the menu to see why they're off.
Can I use it alongside Spectacle?
Both react to the same shortcuts, so use just one. If Spectacle is running (even if it starts later), Split asks whether to quit it, and quitting also removes it from your login items. If Rectangle or Magnet is running, the Settings window warns that shortcuts may clash.
How is it different from macOS window tiling?
macOS 15 added built-in halves and quarters. Split adds thirds, size cycling with the same key, auto-arrange for up to nine windows and re-placing windows when displays change, and every shortcut can be changed.
What happens when I unplug a display?
Its windows move to the remaining screens and return when you plug it back in. You can turn this off in Settings.
How do updates work?
Once a day Split checks for a new version and downloads it ahead of time, then shows what's new and asks before installing. Use Check for Updates… in the menu to check right away, or turn off the Check for Updates Automatically switch. If you installed with Homebrew, brew upgrade --cask split works too.
Does it start at login?
Yes, it's on from the start. To stop it, turn off the Open at Login switch in the menu or in Settings. If you hid the menu bar icon, open Split again to get back to the Settings window.
What data does Split send?
Nothing by default. Split only goes online to check for updates. Only if you sign in to a RUNNERS account on the Phone tab in Settings does it send the computer name, display info and the names of saved layouts to the RUNNERS server, so it can connect to the phone app. Saved layouts write app names, window titles and positions to a file on this computer only.
How do I remove it completely?
If you used Homebrew, brew uninstall --zap --cask split also removes its settings. If you downloaded it yourself, move Split from Applications to the Trash and delete the ~/Library/Application Support/Split folder too. On Windows, remove Split in Settings › Apps, then delete the %APPDATA%\Split folder; on Linux, delete the ~/.config/Split folder.
How do I report a problem?
Choose Help & Feedback in the menu to open the GitHub issues page, and leave a note there.
