Newbie - apologies. I have an iPhone 6 running 8.1.1 and a MacBook Pro 15" Retina running Yosemite 10.10.1 The iPhone 6 has a setting called "Hotspot". I turn that on but my MacBook Pro would not connect to it. Well, it said it had connected but I could not browse the internet nor get my email (from Futurequest in Florida). This happened in Concord, NH at a hotel where they were having problems with the WI-FI. I thought I could get my mail via the hotspot, but no joy. Anybody have any ideas? I'm currently back home, some 3 hours north of Concord, NH.
