[Elecraft] MacOS High Sierra FTDI driver issue

[Bill Frantz]

I upgraded my computer to MacOS High Sierra and found it could 
not contact the K3. The K3 utility failed, RUMlogNG failed, and 
wsjt-x failed. I found the following by robertklep on the web:

What seems to have worked for me is actually removing the FTDI 
driver (/Library/Extensions/FTDIUSBSerialDriver.kext), after 
finding that Apple ships an FTDI driver with the OS itself (/System/Library/Extensions/AppleUSBFTDI.kext).

I moved the driver out of 
/Library/Extensions/FTDIUSBSerialDriver.kext and things started 
working again.
