Hi All I have the New TB MBP and I'm trying to resolve an issue trying to run an external monitor. I have a Dell S2715h - with HDMI input and an HDMI-to-Thunderbolt 2 cable, and an older Apple Cinema Display ( silver body ) with an Thunderbolt 2 adaptor. Both run perfectly on my old 2015 MBP. But they don't work on the new MBP. I'm using an Apple Thunderbolt 2 - to Thunderbolt 3 adaptor to connect them to the new MBP Any suggestions gratefully received.
