I have a mac pro II with 8 core. 4TB disk and I wanted to hook up a black magic multibridge eclipse to it for video editing and capture by final cut. I had to downgrade the mac pro to 10.5 version and I upgraded the latest software for the black magic which is 7.5. I did the same to my other mac pro II with same configuration and the other multibridge eclipse is working fine.
Now the msg pops up as soon as I start the computer is "An error has occurred that has prevented the firmware on your Decklink card from being upgraded. Try restarting your Macintosh and upgrading the firmware again". I did that like a million times. Also I tried changing the USB cables but still no show. I think this is why my Final Cut is not recognising the Black Magic Unit.
Please help I have to solve this problem ASAP. Any help will be highly appreciated.
