For the newest systems from Apple which are the MacBook Pro (Late Model 2016) with only USB-C ports that requires the use of a USB-C to USB-A adapter, we have identified a problem with this new MacBook Pro where it does not provide a proper data stream to the interface. You need to connect a USB hub (powered or un-powered) in between the interface and the computer and the problem will resolve itself.
We have reported the issue and Apple is aware of the issue.
