IOS – Internet Sharing to iPhone over USB not working

This works on macOS 10.12 and iOS 10 without needing a jailbreak or other app.

Later macOS 10.13 enhanced this feature as part of asset caching and Apple Configurator 2 features for multiple iOS devices sharing the Mac network. This is out of the box support, built in to the OS with no extra first party apps or modifications needed.

Before iOS 10 and macOS 10.13, USB tethering only worked in one direction or for one device. Before macOS 10.12 - internet service used to flow out of iOS but not in to iOS from a Mac over USB.

Okay, so I got it to work again. I had to manually enter the correct DHCP, IPv4, and DNS settings on the MacBook Pro.

Here are the settings I used to get it to work in Network Preferences on the MacBook Pro:

I had previously tried to do this manually, but I only tried the IP address stuff, I didn't think about entering in the DNS server until I read this article: http://forums.beyond.ca/showthread/t-216916.html

It's dumb that I have to do this manually now, and that I still am unable to see AirPlay/AirPort devices.
