Using Aurora(n) with Thunderbolt 3 connection and MacBook Pro, and get error message to connect Power Supply

Thunderbolt 3 is capable of delivering power to charge the battery on an MBP. If an AC power source is not connected to the laptop, it will try to derive power from the Aurora(n), unsuccessfully, and thus you will get this message on the Aurora(n) front panel: "Please connect external 12V DC power supply for bus powered Thunderbolt devices".

To resolve this, either plug in the AC power supply for the laptop, or use a powered dock that can successfully charge its battery while in use.
