Sony DCR PC1E dv cassette to Mac cable

Hi there

In the past I've used my firewire 4pin to 6pin to import video from DV cassette, however that was a very old iMac and I no longer have a port for the 6pin connection on my macbook or iMac. The Macs have two thunderbolt versions, hdmi & usb 2.

What cable or adapter do I need to connect to PC!?

Thanks.
