I need a thunderbolt dock for my trash can mac pro. I see a couple TB2 docks on the market, but much more TB3 ones obviously. Can I use the OWC TB3 dock with a TB3 to TB2 cable? Would I miss out on any of the dock's features besides the TB3 speed? Reason I'm asking, the docks are fairly expensive and I don't want to have to invest in more dead end TB2 stuff if I don't have to. At least I could potentially use a TB3 dock with say a new Mac Pro 7,1 etc down the road. Thanks for the help.
