Mar 9, 2015 9:44 AMby Rafaromao81,Unfortunately It is not working yet. The Mac screen becomes dark and the TV too but 2 seconds later show as "no signal"
For many times I had to try like 20 times to get connection but now not working anymore.
I have tried my mini DVI - HDMI adapter on a Macbook air and it worked well so its not the cable, adapter or even monitor.
It started to happen on first version of Yosemite
Thanks
