Have you definitely checked the firewall settings for whatever the mac equivalents of Soolooshelper.exe, sunccompanion.exe and controlpc.exe ?

Maybe a un- and re-install of C-Mac might be needed.

I had the spinning wheel not connecting issue first time around and it was defo firewall for me.

Oddly, having rebuilt the pc last weekend and reinstalled I didn't have to tweak anything.

Does your BT HH show it as connected to 192.168.1.100 ?
