• macOS 15+
• Xcode 26+
• Command Line Tools for Xcode (xcode-select --install)

Steps

1. Get source code by executing the following command in Terminal.app.

   git clone --depth 1 https://github.com/pqrs-org/Karabiner-Elements.git
   cd Karabiner-Elements
   git submodule update --init --recursive --depth 1
   

2. (Optional) If you have a codesign identity:

   1. Find your codesign identity.

      security find-identity -p codesigning -v | grep 'Developer ID Application'
      

      The result is as follows.

      Your codesign identity is 8D660191481C98F5C56630847A6C39D95C166F22 in the above case.

   2. Set environment variable to use your codesign identity.

      export PQRS_ORG_CODE_SIGN_IDENTITY=8D660191481C98F5C56630847A6C39D95C166F22
      

   3. Find your codesign identity for installer signing.

      security find-identity -p basic -v | grep 'Developer ID Installer'
      

      The result is as follows.

      1) C86BB5F7830071C7B0B07D168A9A9375CC2D02C5 "Developer ID Installer: Fumihiko Takayama (G43BCU2T37)"

   4. Set environment variable to use your codesign identity for installer signing.

      export PQRS_ORG_INSTALLER_CODE_SIGN_IDENTITY=C86BB5F7830071C7B0B07D168A9A9375CC2D02C5
      

3. Build a package by executing the following command in Terminal.app.

   make package
   

   The make script will create a redistributable Karabiner-Elements-VERSION.dmg in the current directory.

Note about pre-built binaries in the source tree

Karabiner-Elements uses some pre-built binaries in the source tree.

• vendor/Karabiner-DriverKit-VirtualHIDDevice/dist/Karabiner-DriverKit-VirtualHIDDevice-*.pkg (the latest one)
• Sparkle.framework in src/apps/SettingsWindow/

The above make package command does not rebuild these binaries.
(These binaries will be copied in the distributed package.)

If you want to rebuild these binaries, you have to build them manually.
Please follow the instruction of these projects.
