Ok, this is very confusing. I'll detail my entire setup and see if we cannot find a discrepancy somewhere. DM 3200: Frimware ver 1.10 and Version IFDW is 1.30f10 (latest) Version is 1.72b4 Updater is Bl1. Computer: You have already seen my computer specs so i will not mention that. Connectors: Firewire 400 to 800, into thunderbolt 2, then thunderbolt 3. Inside the DM's 'slot' menu the driver states 'driver offline.' and if i unplug the connection will change to 'no cable'. I also bought a DOck station, where i can plug the firewire cable into the diocking station, and then connect my macbook pro into the docking station. The computer does indeed recognise the docking station, but still no communication with the DM. I think i have covered everything. So its a mystery why it is not working. I have restarted everything before, and will try yet again. But failing that i think i have tried literally everything, unless you can think of something otherwise.
