Bringing footage onto Imac w/bmcc

So I am unclear with my options for uploading footage onto my 2011 imac, which only has firewire 800 and usb 2.0 inputs. Using the standard black magic cinema camera, is there an adapter I can purchase? Or is my solution getting an SSD reader? If so which one would best suit me?
