I just got a new IC7300 and for the life of me can't seem to get it to work on my mac with WSJTX. I downloaded the driver for a mac and installed it. I plug the radio in and get no indication at all. When I turn on WSJTX it doesn't connect to the 7300 despite checking it off under radio. I've watched some videos on it with no luck. I changed the setting in the 7300 with no luck. I can't even verify the compute recognizes the radio. Until I got this rig I've been using my IC735 with signaling on the mac computer. Works perfect. Do I need to re configure WSJTX on the mac all over again?? Any ideas???
