iPad USB-C Internet Connection: Tethering to Macbook I have an iPad Pro (2018 3rd Gen) with a USB-C Port and a 2018 Macbook Pro with a USB-C Port. Can I tether the iPad to my Macbook's Internet connection using a USB-C cable?
Yes, you can use a USB-C cable to share Macbook's Internet connection with the iPad just like the USB to lightning cable does on iPhones and older iPads. 

Benefits:


The USB-C cable powers the iPad directly from the Macbook reducing the number of mains sockets you need to just one.
WiFi &amp; Bluetooth can be completely turned off on the iPad.
Traffic is proxied to the iPad via the Macbook (which has a firewall in front of it).


Negatives:


Airdrop and Sidecar will not work with your wireless interfaces down.


Parts Required:


Standard USB-C charging cable that came with your iPad will work
Or this short (and tidy) Anker USB-C cable I've found works well


Internet Connection:

You Macbook should have a non-802.1x Internet connection to share, ie: straight WiFi.  If your WiFi connection is secured using EAP-TLS (with certificates) or other 802.1X security to stop this sort of thing, the USB-C Internet connection sharing won't work.

Configuration:

On Macbook Pro: "System Preferences" > "Sharing" > "Internet Sharing" and tick "iPad USB" as below:



Connect the USB-C cable between them and you're done.



It's a tidy, secure solution.
