I just ordered a new Macbook Pro, I want to get a USB-C dock for it. I noticed for the OWC's dock, it can supply 80W of power. But the MBP included an 87W power adapter. So how can I tell the OWC dock not to supply power, and for the computer to rely on its own power adapter instead? Alternatively, is there a better option for the new Macbook Pro in terms of docking?
