I just found this so I guess I won't do that. Do not do this

If you're lucky, nothing will happen.

If you're unlucky, one or both laptops will short circuit, because an hdmi transmitter sends a 5V power signal. by plugging two transmitters into each other, you send +5V from both sides, which can damage one or both computers, if they aren't designed with protection circuitry.


Applecare didn't hang up on me. He promised to call me back because he needed to do some research. Now I have no OS in my computer. The only thing I can think to do is to get an ethernet adapter and do it that way. This is all b/c they took our ethernet ports away and OS CDs away and now everything is a big deal. Otherwise I have to make an hour trip to a genius bar or some authorized repair service. frown

I was told the mail probably was buggy because I downloaded the update from the App store, but if I did it through recovery there wouldn't be a bug! What? A bug from the App store?

What version do you have? It it's not Sierra or not the latest, count yourself lucky.

(I know only a little about HDMI, but I'm pretty sure that what you propose to do won't work...not the right functionality.)
