SIP configuration

Required for macOS 11 and later only.

Since macOS Big Sur (11), Apple requires kexts to be signed with a certificate that is no longer issued to new developers. To load HoRNDIS, kext signing must be disabled in SIP:

1. Shut down your Mac
2. Boot into Recovery Mode (hold Cmd+R on Intel Macs)
3. Open Utilities → Terminal and run:

   csrutil enable --without kext

4. Restart

Installation

• Download the .pkg from the Releases page and run the installer
• If macOS blocks the extension: go to System Settings → Privacy & Security and click Allow

Configuration

• Connect your phone to your Mac by USB
• On your Android phone, open Settings and navigate to the network or hotspot section (the exact path varies by manufacturer and Android version)
• Enable USB tethering
• The connection should appear automatically in your Mac's network settings

Uninstallation

sudo kextunload /Library/Extensions/HoRNDIS.kext
sudo rm -rf /Library/Extensions/HoRNDIS.kext
