I have installed the Prolifics USB driver on my Mac and can connect with a USB cable through the hand controller to the mount using SkySafari 6 Pro.
The connection is SkyWatcher SynScan or SkyWatcher SynScanLink (one uses the new USB port and the other an existing port).
On a PC laptop, I have WiFi Scope installed to access the mount, which works and also provides access on port 4030.
The problem is that in SkySafari Telescope --> Settings... on the Mac connection to my laptop's IP address and port 4030 doesn't connect.
The Mac is indoors. The PC laptop and mount are also indoors (for now), but will later be taken outside.
