I bought a thunderbolt 2 dock last week as soon as I set it up and turned it on it got very hot, do all docks get hoy like that? The guy reviewing this dock said he did not think it would get that hot. The other thing is why does it not show up on my Mac? When I type Thunderbolt 2 dock on Alfred it takes me to a page on the web about Thunderbolt. I would have thought there would have been a thunderbolt icon in the system preferences.in this review the guy says there is all so a connection at the back for speakers bit that does not work. I have the speakers connected on the side which he says are for headphones.
