USB Tethering

This substantial discussion on the same issue came up with a POSSIBLE third-party software solution, but the original Poster has not stated that it works with the latest MacOS:

Hi meetpatel_05,

Regarding tethering via USB from an Android to a Mac, it's not possible. You can view details below and from the Android support page here: Share a mobile connection by hotspot or tethering on Android

"Tether by USB cable

Important: Mac computers can't tether with Android by USB.

1. Connect your phone to the other device with a USB cable. A notification shows at the top of the screen.
2. On your phone, swipe down from the top of the screen.
3. Touch and hold Hotspot.
4. Turn on USB tethering."

Hope the information helps clarify the issue.

Cheers.
