I have a MacBook Pro late 2013(IG model). It has only 2 USB 3 ports and 2 thunderbolt 2 ports. Its hard to find anything I need in thunderbolt at any reasonable price. But I can't seem to find an adaptor which allows at least a 1-1 connection on the thunderbolt 2 ports on the side. I'm sure they are out there. I just can't find them. Can anyone point me to some examples?
