How do I share my Wi-Fi connection through USB to my MacBook Pro without using cellular data or hotspot?
First, turn tethering on. Then, plug your phone via USB. Open system preferences on your Mac. Click network, then check the left side for your iPhone. If it's there, you're good to go. Else, click the '+' button. Set the name to whatever you want and set Interface to iPhone USB. The, restart tethering on your phone.
