Does the thunderbolt of this model of iMac work for external storage?
My iMac is the model of iMac Intel 27" EMC 2429, mid 2011, which has 2 thunderbolt ports (yes, I cofirmed it is thunderbolt), which I have never tried to use until now. I tried the thunderbolt converting to VGA and it works fine. However, when I connect the imac to an external storage or converting it to USB 3.0, it does NOT work. The cable has no problem. It is a brand new cable bought from apple store, and it works fine on another mac book air.
My question is, does the thunderbolt of this model of iMac really support external storage? Or it is my thunderbolt ports have some problem? I asked apple support, they said all thunderbolt ports should work for external storage inclusing this model.
Is this a good question?
