Does anyone know how I can connect my old firewire 800 drives and peripherals to the new USB-C (Thunderbolt 3) ports? What I found so far is Apple's 'Thunderbolt to Firewire adapter' ($29) coupled with Apple's 'Thunderbolt to Thunderbolt 3 adapter' ($49), or an OWC Thunderbolt 3 Dock ($299). I would be great to just have one small adapter that is cheaper than the above two alternatives.
