Anybody having issue using this adapter with Sierra? I’ve been using this adapter with El Capitan and it was working fine outputting [email protected] to my Sony X800D tv. This morning, I made a bad decision(without even googling) and update my mac to Sierra. Now, it won’t output at 60hz anymore. All I can see is pink line. There are so many people having issue with external display with Sierra. I should have googled it before I update it. Anybody here having same issue? I have 2015 Mackbook pro 15″.
