[QUOTE="AlVista, post: 1729110, member: 382510"] I have a new Macbook Pro (2015) which I use mainly for lecturing. I go from place to place, usually using their projector. Sometimes there is WiFi in the hall and sometimes not. The Macbook is Airplay capable. I would like a bit of hardware to plug into any projector, that I can mirror (extend) the Macbook screen to, thus being able to use the presenter capabilities of Keynote or Powerpoint wirelessly instead of having a long trailing cable. My understanding so far is that an Apple TV box would do this when there is WiFi present, but that it would fail where there isn't. I also understand that the Macbook itself is capable of being a WiFi hotspot, though when doing so could not connect to the internet (but I wouldn't need to do that). So: 1. Can I use the Macbook's self-generated hotspot to connect and mirror with an Apple TV? 2. Or is there some other unit I could buy, small and portable, that I could use to achieve my goal? [/QUOTE]
