No, it is not. The current MacBook Pro and iMacs do carry TB3 through the USB C port. Other Macs with USB C, including the MacBook Air, do not (Apple just says TB—probably TB1).

You are correct. Thanks for the clarification.

I think I was trying to show that, in the Macs I use anyway, there didn't need to be three adapters to get from TB3 to Firewire400. You explained it much better!

Also - I really appreciate your very experienced posts, both here, and on the Finale sites. I have learned quite a lot from the really clear and practical info you offer. Thanks!

Just an idea: did you ever check System settings->Security, tab "general" after connecting the interface and loading CueMix/DP?

There might be a message/warning and a button to allow the driver to load.

My memory might fool me here, but I think I once had to allow something to load there after upgrading to High Sierra. Good luck!
