  1. Build a package by executing a following command in Terminal.app.

cd Karabiner-Elements 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.

  • src/vendor/Karabiner-VirtualHIDDevice/dist/\*.kext
  • src/vendor/Sparkle/Sparkle.framework

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.

About rebuilding kext in Karabiner-VirtualHIDDevice

If you want to build kext in Karabiner-VirtualHIDDevice, macOS requires a valid certificate which be able to sign the built kext.
Unless such certificate, macOS refuses to load the built kext.
Please read a documentation about System Integrity Protection Guide for more details.

(We are including the pre-built kext binary to avoid the restriction that macOS requires a uncommon certificate.)
