My iPhone wireless hotspot quit working, but I can still use the internet through a USB connection. I’m wondering if I can use internet sharing on a MacBook Pro to share the USB internet connection from my phone. I attempted this and found the shared connection on my Apple TV. It connected but didn’t seem to provide internet to the Apple TV. I have another device I would like to use this shared connection with but I have to buy a WiFi adapter to test it. Prior to buying that, I thought someone here may be able to answer if this is even possible.
This is possible using System Preferences > Sharing > Internet Sharing.
Cell Network > iPhone > USB > MacBook Pro > Wi-Fi > other devices
In fact, you have to do it this way as the Wi-Fi on your MBP can either join or create a Wi-Fi network, it cannot do both at the same time.
Also, you should check usage terms of your mobile data provider to see if they allow sharing of personal hotspot in this way - some do not.
