Thank you for your message. I am trying to be nice but the questions and the information was already detailed in my original posts. If there is no one that has an actual solution then why should I answer questions that I have already detailed?
I bought my first Macintosh computer in 1984, In 1985 I became a Value-Added Reseller for Apple and was a Certified Developer too. I have spent over 35 yrs as a computer technician - self employed.
I did not ask How do I turn on a Hotspot on my iPhone? I asked how is it that the Mac see's it and opens iTunes yet it doesn't see it is even connected by USB in Network settings. If the people on this forum don't have an answer; don't waste my time! I'm not rude. People who ask questions that have already been answered are the rude ones.
Thanks for your concern but clearly you don't know why either!
And apparently no one else on this forum has a clue either.
