In the ~10 minutes or so it took me to compose my message yesterday, the (different) computer I had connected to the radio just sat there.  I guess it needed the rest? after sending off my plea for help, I turned back to it and tried again.  Success!

Upon plugging in the KX3 and lighting up the KX3 Utility, it immediately connected to it.  I don?t recall seeing anything in the Elecraft literature suggesting that 10.12 is required? but it definitely seems to help.  I?ve now talked to the KX3 with two different computers.  How reliable that connection might be, I suppose time will tell.

Hi.

This sounds more like the USB<>KX3 cable driver firing up as a Serial
port that the updater was not defaulting to.    That can happen if there
is something else already connected to the computer that provides a
"Serial" port for some other reason, before you plug in the KX3 cable.

I've never seen the KX3 utility run on an Apple box, but on Windows and
Linux, you get a chance to find and specify the serial port to use.

(Also just recently updated a KX3 to the latest releases with no issues,
using Linux Lite on an Acer One Netbook.)
