So I just got my WIDI XU and X8 combo and I definitely need some help getting it to work with my Mac. I hope someone can help. Here\u2019s the situation: I plug the XU in my computer with the X8\u2019s power on and both signal lights turn green. BUT I can\u2019t seem to play a MIDI to any output except my computer\u2019s own speakers. When I go to System Preferences/Sounds the only option listed there is Internal Speakers. ;The XU appears in Applications/Audio Midi Setup but there didn\u2019t seem to be any other sort of instructions or pop-ups when I first put it in the USB port. Should there have been? Can anyone help me figure out how to tell the computer to send midi files to a USB device?
