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.

From Source/Binary

  • Get the installation package (Download or Build the installation package from source yourself)
  • Run the installation package

From Homebrew

brew cask install horndis
sudo kextload /Library/Extensions/HoRNDIS.kext


  • 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
