I spend a lot of time in a hotel with work which has wifi only Internet connection, 1 gadget only and if you log off my mac it won't let me use it on the iPad etc so I have to pick one gadget and I'm stuck with that only for the week. I have 2013 macair, iPad and iPhone. Is there anyway to log in off one of these but then share the connection with the others? Ie connect on my mac direct to Internet but then connect iPad or iPhone to the macair to the Internet? Thanks complete novice so simple explained answers appreciated!!
