I put the carriage before the horse and just bought this interface slightly-used, but I’ve decided not to invest in a computer with Thunderbolt 3 connections, so I’m listing it for sale. It’s a 2 input interface that runs on bus power through Thunderbolt 3, and has DSP onboard so you can run plugins using the processing power of the interface rather than your computer. I don’t have a TB3 port on my ages MacBook Pro so all I can tell you is that it has great reviews and that it works as it should. UA also says while it should theoretically work with a TB2 adapter, they have not tested it that way. NOTE: this doesn’t come with a TB3 cable. I will transfer the UAD license for the included plugins to the new owner. I’d trade towards other similarly priced USB or Thunderbolt 2 capable interfaces.
