How do I install HoRNDIS using Homebrew?

Run 'brew cask install horndis' in Terminal, then execute 'sudo kextload /Library/Extensions/HoRNDIS.kext' to load the kernel extension. Connect your Android phone and enable USB tethering in settings.

Is HoRNDIS better than Wi-Fi tethering for Mac?

HoRNDIS provides a more reliable wired connection with lower latency and battery usage, but it requires driver installation, whereas Wi-Fi tethering is built-in but can be less stable.

Why did HoRNDIS stop working after a macOS update?

macOS updates often change kernel extension policies or networking stacks. Check if the kext is still compatible; you may need to reinstall or check for updates, as kernel extensions can break with system changes.

How to completely uninstall HoRNDIS from my Mac?

Delete the HoRNDIS.kext files from /System/Library/Extensions and /Library/Extensions, then restart your computer. Follow the uninstallation steps in the README to ensure no remnants remain.

Does HoRNDIS work with iPhones or only Android?

HoRNDIS is designed specifically for Android devices; iPhones use different tethering protocols, so it won't work. For iOS, macOS has native support via USB or Wi-Fi tethering.

How to troubleshoot HoRNDIS when my phone isn't detected?

Verify USB connections, ensure USB tethering is enabled on your phone, and use debugging tools like 'ioreg' or system logs from the README to inspect device recognition and driver matching.

What is HoRNDIS?

HoRNDIS is a kernel extension for Mac OS X that enables USB tethering from Android devices, allowing users to share their phone's mobile internet connection directly via USB. It solves the problem of macOS lacking native support for Android's USB tethering mode, providing a reliable wired alternative to Wi-Fi hotspots.

Target Audience

Mac users who need to tether internet from an Android phone, especially those preferring a stable USB connection over Wi-Fi or dealing with unsupported tethering apps.

Value Proposition

It's a lightweight, open-source driver that leverages Android's built-in tethering without requiring phone-side software, offering better reliability and integration than third-party solutions.

Overview

Android USB tethering driver for Mac OS X

Use Cases

Best For

Sharing mobile internet from Android to Mac via USB cable
Avoiding unstable Wi-Fi tethering connections on macOS
Using Android's native tethering feature on unsupported Mac systems
Developers needing network access in environments without Wi-Fi
Users preferring wired connections for lower latency and battery usage
Troubleshooting network issues where USB tethering is more reliable

Not Ideal For

Users on macOS versions where kernel extensions are deprecated or blocked by System Integrity Protection
Cross-platform environments requiring tethering solutions that work on Windows or Linux
Non-technical users who prefer plug-and-play wireless tethering without driver installations

Pros & Cons

Pros

Native Android Support

Leverages Android's built-in USB tethering mode, so no additional phone software is needed, as stated in the README's configuration steps.

Homebrew Installation

Available via Homebrew Cask for easy package management, simplifying updates and removal compared to manual installs.

Kernel-Level Performance

Installs as a kernel extension for low-level network handling, offering potentially better stability and integration than user-space solutions.

Detailed Debugging Notes

Includes comprehensive guides for troubleshooting with system logs and USB diagnostics, as shown in the README's debugging section.

Cons

Unreliable Logging

The README admits that macOS logging is unreliable on Sierra and later, making debugging difficult due to garbled or missing messages.

Kernel Extension Risks

Requires loading a third-party kext, which can cause system instability, security vulnerabilities, and compatibility issues with macOS updates.

Manual Configuration Steps

Installation involves sudo commands and manual kext loading, such as 'sudo kextload', which isn't fully automated and may deter casual users.
