A: I haven't connected a PC to a Sony VTR since the BVU models were prevalent, however I have used the TBT3 to attach 1394a & b audio interfaces to a Thinkpad P70 instead of ZBook G3. The FW inferfaces are Apple-centric with the LSI(Agere) chip, one being the Apple TB-FW inline adapter and the other is in an OWC Thunberbolt 2 dock. I've run them one at a time off of the TBT3 as well as daisy-chaining the Apple adapter to the OWC. The daisy chain setup successfully records simultaneously from an RME FF800 and FF802.

Q: 4. Is there a split version of this cable? I would need it to attach a thunderbolt device to the macbook retina. Of course then I loose the power charging cable. or would the macbook get power from thunderbolt devices?

A: This cable will not work with the retina MacBook because the retina MacBook has no Thinderbolt capability. The retina MacBook has a USB-C port but it only supports USB 3.1, not Thunderbolt. This adapter requires that Thundebolt 3 be supported behind a USB-C type port in the computer. As of July 2016, no Mac supports Thunderbolt 3 behind a USB-C connector, although this capability will most likely be integrated in Macs coming out in the fall 2016.
