Internet Sharing to iPhone over USB not working I'm unable to share my macOS Ethernet connection with my iPhone over USB. I tried both the 'Internet Sharing' and the 'Content Caching' methods. I can see the iPhone in Finder but the iPhone does not connect to the internet. I can also see and select 'iPhone USB' inside 'Internet Sharing' when the iPhone is connected.
macOS: 10.15.7 - iOS: 14.1
I'm testing in an iMac 2020 with a built-in Ethernet adapter and the iPhone is directly connected to a USB port on the Mac. There is only one Ethernet port in System Preferences &gt; Network
Should it suppose to appear as Ethernet on the iPhone?
Try this tutorial.  It will share your ethernet over Bluetooth instead of USB.
