D.J. Ring has been very helpful in his ongoing patient advice on this issue, and asked me to outline the drivers on my 10.9.5 Macbook. I have zero background in computers and such, and so much of the advice from others goes right over my head, and I am sure many others. Here is the list of drivers on my Mac with the Valley Ent. cable plugged in.

USB Hi-Speed Bus Apple USB-EHCI OxO aa9

and an aa6, and an OxO5ac, and an OxO aa7

FT232R

vender ID: FTDI

location: OxO620000000 / 3

BRCM2046 Hub

OxOa5c (Broadcom)

location: OxO610000000 / 2

then some other Apple related "keyboard" and "IR Receiver" related stuff.    NOTHING ELSE!

Does that mean I have all that I need in order to program my Yaesu 2900R on CHIRP or not?
