I guess I'm not being clear. I don't think the Mac moves the
DTR/RTS lines when it boots. I haven't ever seen the K3 go into
transmit mode when I reboot.
Of course that might be because I have PTT_KEY set to OFF-OFF
and use VOX for sound card modes except wsjt-x and RUMlogNG
contest mode. (They use the CAT interface.)

If you have updated the K3 firmware in the last few months, it
does not make any difference whether the K3 or the computer is
turned on first.
The K3 now has a SAFE mode that disables DTR and RTS until it
receives some command like polling for frequency, mode, etc.
from your software application.
You can go into the K3 CONFIG menu for KEY-PTT and turn it to
unsafe if you have devices that monitor the RS-232 bus and do
not issue any commands (SteppIR controllers for one instance).
Look at the firmware release notes for the past 3 months.
BTW, the firmware release notes should be considered an
addition to your K3/K3S manual. Do not overlook them.

On my Mac system, it doesn't seem to matter whether the radio

K3 is powered from the computer with enough functionality that
the computer recognizes it without the radio being on.
In any case, start wsjt-x last because it will try to talk to
the radio for rig control and harass you until it can succeed.
I've been in this situation enough times to know that starting
the radio, waiting until the radio is ready to talk to the
computer and then clicking "Retry" works.
