I can confirm Tom's idea, CAT command keys the radio but audio not come
through, same as VOX..
You must have extra RTS/DTR keying..
Easiest way is USB-RS232 adapter and add optocoupler circuit to RTS (or DTR)
pin.
See https://www.nf8m.com/nf8m/rig-control-and-keying/.
Unfortunately can't help with software, have never had an Apple..
If you are not polite with soldering, the interface is needed.
Sth like https://www.gigaparts.com/yaesu-scu-17.html or
http://microham-usa.com/store/product-info.php?pid6.html etc.
This is much more expensive, but easy to use.. :-)
Best regards and CU on another bands, not just 17m.. :-)

Hi Ed
Just a guess as I don't have a FTdx-1200, how are you doing PTT? Older Yaesu
transceivers required you to ground the PTT pin in the data jack to transmit
audio. IE if you are are using some other method to switch the xceiver to
Xmit, it will not work. You have to ground the PTT pin in the data jack. And
you can't get around this by using VOX to switch. Has to be the PTT pin in the
data jack.
As I said, that's the way older Yaesu rigs worked.
Good luck, FT8 is a great mode.

I’ve been trying to sort this out but am not getting anywhere.
If I plug a headset into the Mac’s audio out I hear the correct modulation
sound coming from FT8.
But when I route the audio out to the data in pin on the FTdx1200 all I
hear on the transmitted signal is noise!
This is true whether I select USB or USB data as the mode on the radio.
