I installed the up grade this morning using my MAC!
I tried to install the up grade on line last light and it wouldn't load, so I down loaded the program to the desk top. This morining, started up the Mac, I connected the iWay, Launched the program. IT wouldn't load, crap, then I see where we may need to "Set" something, so I went to the Lowrance web page, copied the code, pasted it in the console (?) box, hit return, turned the iWay off and back on, clicked on the program again and it worked.
