When you go to devices on your computer and you see the Lpc shown, look for the properties tab for it. On pc it says drivers etc...if it shows none that means you will have to down load the drivers for the Lpc basically the drivers for the go itself. On the line 6 pod go download software page try downloading the Mac version of the line 6 updater and the line6 drivers v.1, something. Do worry about having the pod go edit program running for the time being while doing this. See if running the downloads work by checking the drivers on the Lpc again. If it works you should see line 6 on the description for the Lpc. Just toy with it and hopefully you’ll get it and you can get the go back to factory and it will be current on the firmware ware.
