HoRNDIS not working on Mac OS Mojave The procedure to get an Android phone to tether the internet connection to a Mac is given on countless websites.  

I followed the instructions provided on the official page (https://joshuawise.com/horndis) but nothing happens.
The connection is not recognised in the Network section of the System Preferences.  

My machine runs a Mac OS 10.14.6 and I'm tethering from a Huawei P20 Lite. 

Anybody got any piece of advice? 

I've added a screenshot of the Network preferences.
I was showing the application was blocked in Security and Privacy section. After allowing it, I could use tethering with my Andriod device.
However I do not see the kext file in Extensions, which seems strange.
