Sorry guys, I have a similar issue , and some people recommends me to buy this adapter, so based on your experience think that my OSX Mountain Lion can recognize my MBOX Pro3 connected through the adapter Thunderbolt to FireWire instead of my integrated FW port in my Imac 2009 with 10.8.2 and using the last drivers available for Mountain Lion Release: 1.1.3 (Oct 30, 2012)??
Thank you.
