For Lightning to Thunderbolt 3, use a USB-C to Lightning cable. Just connect the USB-C plug to the USB-C or Thunderbolt 3 port on a source. Link HDMI to Thunderbolt 3 via a USB-C Digital AV Multiport Adapter. This leads me to believe that there is something within the software 'inhibiting' the use of this cable. The plug-and-play USB Type-C to HDMI cable requires no software or external power. I find this very strange, as the product specifications of the Thunderbolt-HDMI cable implied it would easily work for my Macbook Air. Many of the forums I have read say there should be an "Arrangement" tab, but this is not appearing on mine. However, when looking in System Preferences/ Displays, there is no trace of any external screen. When connected to the TV via the Thunderbolt-HDMI cable, a blue screen briefly appears on the Macbook. I tested to see if it was the cable which is the problem by connecting it the Thunderbolt port of a laptop supporting Windows 7 and it worked PERFECTLY on my Samsung television.

I have scrolled and read through a VAST amount of forums and so-called "help pages" on the internet but can't find anything that works for me, however there do seem to be many people with the same or similar problems.


I have spent all day trying to get my Macbook Air (OS X 10.8.4) to display on various televisions via a Thunderbolt-HDMI cable, however I am yet to suceed. Simply attach the Lightning Digital AV Adapter to the Lightning connector on your device and then to your TV or projector via an HDMI cable (sold separately).
