Tiling window management for the Mac.

CI Status Badge License Badge Changelog Badge Version Badge



yabai is a window management utility that is designed to work as an extension to the built-in window manager of macOS. yabai allows you to control your windows, spaces and displays freely using an intuitive command line interface and optionally set user-defined keyboard shortcuts using  skhd and other third-party software.

The primary function of yabai is tiling window management; automatically modifying your window layout using a binary space partitioning algorithm to allow you to focus on the content of your windows without distractions. Additional features of yabai include focus-follows-mouse, disabling animations for switching spaces, creating spaces past the limit of 16 spaces, and much more.

Installation and Configuration

  • The  yabai wiki has both brief and detailed installation instructions for multiple installation methods, and also explains how to uninstall yabai completely.
  • Sample configuration files can be found in the  examples directory. Refer to the  documentation or the wiki for further information.
  • Keyboard shortcuts can be defined with  skhd or any other suitable software you may prefer.

Requirements and Caveats

Please read the below requirements carefully. Make sure you fulfil all of them before filing an issue.

Requirement Note
Operating System macOS High Sierra 10.13.6, Mojave 10.14.4+, Catalina 10.15.0+ and Big Sur 11.0.1+ is supported.
Accessibility API yabai must be given permission to utilize the Accessibility API and will request access upon launch. The application must be restarted after access has been granted.
Mission Control In the Mission Control preferences pane in System Preferences, the setting "Displays have separate Spaces" must be enabled.

Please also take note of the following caveats.

Caveat Note
System Integrity Protection System Integrity Protection needs to be (partially) disabled for yabai to inject a scripting addition into for controlling windows with functions that require elevated privileges. This enables control of the window server, which is the sole owner of all window connections, and enables additional features of yabai. If you are running on macOS High Sierra 10.13.6, you can reenable SIP after the scripting addition has been installed.
Code Signing When building from source (or installing from HEAD), it is recommended to codesign the binary so it retains its accessibility and automation privileges when updated or rebuilt.
Mission Control In the Mission Control preferences pane in System Preferences, the setting "Automatically rearrange Spaces based on most recent use" should be disabled for commands that rely on the ordering of spaces to work reliably.
