Installing yabai (latest release)

A codesigned binary release of yabai can be installed using Homebrew from the tap koekeishiya/formulae.

brew install koekeishiya/formulae/yabai

Open System Preferences.app and navigate to Security & Privacy, then Privacy, then Accessibility. Click the lock icon at the bottom and enter your password to allow changes to the list. Starting with brew services start yabai will prompt the user to allow yabai accessibility permissions. Check the box next to yabai to allow accessibility permissions.

Now install the scripting addition.

# install the scripting addition
sudo yabai --install-sa

To run yabai, simply start it and then restart Dock.app to load the scripting addition. Alternatively you can also logout and login again.

# start yabai
brew services start yabai

# load the scripting addition
killall Dock
