C++ Makefile Shell
Latest commit ae2d0f7 @jwise Why build one kext when you can build two? Fixes build under 10.11 by…
… splitting archaic OS X build into a different configuration (thanks, @d235j, for the suggestion; no thanks, Apple, for the regression).  Progress towards issue #42.

HoRNDIS(the USB tethering driver for Mac OS X)

HoRNDIS (pronounce: "horrendous") is a driver for Mac OS X that allows you to use your Android phone's native USB tethering mode to get Internet access.

For more information, visit the home page for HoRNDIS on my site.


  • Get the installation package (Download[^download_footer] or Build the installation package from source yourself)
  • Run the installation package
  • Assuming that the installation proceeds without errors, after it completes, connect your phone to your Mac by USB.
  • Enter the settings menu on your phone.
  • In the connections section, below Wi-Fi and Bluetooth, select “More...”. Select “Tethering & portable hotspot”.
  • Check the “USB tethering” box. It should flash once, and then become solidly checked.


  • Delete the HoRNDIS.kext under /System/Library/Extensions and /Library/Extensions folder
  • Restart your computer

Building the source

  • git clone the repository
  • Simply running xcodebuild in the checkout directory should be sufficient to build the kext.
  • If you wish to package it up, you can run make to assemble the package in the build/ directory
