It is a duplicate of the question posted here however there is no answer to that question and one of the commenters is wrong about the direction of sharing. I am posting this again to hopefully get a solution for this.
I have enabled internet sharing in OSX via settings -> sharing then clicking on internet sharing. I have tried this using wifi which works just fine, however I am no longer allowed to create a wifi network because security.
My new plan is to use the iPhone USB option to share my Mac's ethernet connection with my iPhone. The setup seems simple and I have selected "Share your connection from: Ethernet" "To computers using: iPhone USB". I don't currently have a connection to the internet. Is there something else I need to do?
