Hi, I have a Late 2012 MacMini 2.6GHz Quad-Core Intel Core i7. The spec sheets say that it has USB 3.0 ports, but when I check the system report, it says USB 2.0. Would anyone know which is correct? It just that I want to connect a fast external hard drive and want to know whether to go with USB 3 or Thunderbolt (I expect that this will be TB1). Cheers.
