    Hey guys!

    I have a 2010 Mid 13" Macbook Pro, and a Thunderbolt to VGA adapter, which i used to connect my external VGA monitor to my mac, for years. Now, that I updated to Yosemite, it's just not quite want to work. I connect it to the adapter, the screen flashes, it detects the monitor, I can see it at settings, i can drag windows to it, but on the monitor, it says "no signal" and stays blank. Any ways to solve it? Tried with different VGA monitors, same result. Only since Yosemite. :confused:

    I'd also check the adapter by testing with a different one and a different monitor. Just to isolate that its Yosemite.

    At some point there was actually some kind of a firmware update for the mDP/TB-to-VGA adapter, I believe. I don't recall all the details, but pretty sure there was something. Is it possible you're using an old revision of the adapter?
