Hooking up the working black cable to the Acer, nothing shows up in the Thunderbolt app. It is application version 1.0.36.0, Controller driver version N/A. In the "Approve TB devices" section it states "The following Thunderbolt device chain has been plugged in and one or more devices require your permission to connect to this system. Select the devices you wish to connect:" and the list is empty. Connecting to the non-working charge/no charge beep loop cable shows nothing in the TB CC.
