Thanks for all the feedback. 
I did open the Terminal and entered the sudo dmesg command.
This is what returned: PL-2303/X V1.5.0 start, Prolific

As I know nothing about Terminal stuff. This looks to me like it detected the driver, but I don’t see any node stuff going on there.
What now?

Thanks,

-Ted

I'm thinking it's simpler than Apple messing with the driver. Have you tried using the commandline to check what is printed when you plug in the cable?

unplug the cable, open terminal and type 

sudo dmesg

plug the cable back in, and type the same again.

It should tell you the cable was detected, the driver was loaded, and what /dev node it's associated with.

IF you don't get a node name, then you can start barking up the driver tree.

Hi Ted,

My son-in-law gave me a MacBook Air a couple of months ago. I'm not a
Mac user so I decided that my first project would be to see if I could
get CHIRP running on it.

Most of my programming cables were furnished with the radios so
virtually every one of the freebies has a counterfeit USB-to-TTL chip
in it. So I knew up front that using device driver from the Prolific
website was out of the question. I also have a homebrew programming
cable that has a Silicon Labs chip and a few programming cables with
FTDI chips.

So what I did was to purchase and install a 3rd party device driver
from Repleo. It works for programming cables with Prolific PL2303
chips, WCH CH341 chips and Silicon Labs CP2102 chips. They want 7.90
euros for it which at the time I bought it came to $9.11 USD.

I used the native Apple driver for my programming cables with FTDI chips.
