Android USB Tethering | HoRNDIS | "Wifi adapter"

Important: Mac computers can't tether with Android.

I don't think so Google.

1. Using a USB cable, connect your phone to the other device. A "Connected as a…" notification shows at the top of the screen.
2. Open your phone's Settings app.
3. Tap Network & internet Hotspot & tethering.
4. Turn on USB tethering.

You should see new Ethernet connection in the network settings. Works with USB Type C and USB A.

If you want to use this feature, enable it in config.plist

Some devices changes MAC adress on every connection, so macOS creates new etherneten connection every time. To delete them, you must remove

/Library/Preferences/SystemConfiguration or included networking plists.

Own prev-lang-kbd settings

Data field accepts HEX data (ProperTree)

Format is lang-COUNTRY:keyboard

• [0] en_US - U.S --> en-US:0 --> 656e2d55 533a30

• [30776] cs - Czech --> cs-CZ:30776 --> 63732d43 5a3a3330 373736

• cs-CZ:0 --> 63732d43 5a3a30

etc.

It's possible to unlock Advanced menu thus disable CFG Lock natively in BIOS + Other Advanced menu benefits. Flasher is needed
