To all that replied. A club member (my local Mac guy) suggested getting the latest FTDI driver, which I did from Elecraft website link.
I did change CONFIG/PTT settings to OFF-OFF. All ok. Tried starting Utility in SSB and CW mode with no errors. Reset CONFIG/PTT to RTS-DTR, all still ok. I think the driver did it. Now, question????? If I set the PTT-KEY to OFF-OFF, can n1mm still use those lines to handle PTT and Keying? I assumed not, but……..
