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. It is known to work with Mac OS X versions 10.6.8 (Snow Leopard) through 10.14 (Mojave – see notes below), and has been tested on a wide variety of phones. Although you should be careful with all drivers that you install on your computer, HoRNDIS has been tested at least well enough for the author (and many others) to run full time on their own personal computers.
HoRNDIS is implemented as a kext, rather than as a user-space program that opens a TAP or TUN device; this means that it does not conflict with other TAP/TUN kexts that you might have installed (like OpenVPN, Tunnelblick, or Cisco VPN). The driver implements Microsoft's proprietary RNDIS protocol, which is the only protocol supported natively by Android devices; although Linux and Windows users have enjoyed native RNDIS drivers for years, Mac OS X supports only CDC Ethernet devices out of the box.1)

The chief advantage of HoRNDIS over other tethering solutions is that it uses the a first-class supported feature in the phone's firmware. Other solutions either take over the phone's Wi-Fi stack without the Android operating system's knowledge, or create an emulation IP stack in userspace on the phone; in many cases, the built-in USB tethering support can be more stable, more reliable, and faster.2)
