What do you mean by CHIRP4 and CHIRP3? The very old "stable" builds
(v0.4.x and v0.3.x from 2014 and before)? These should not be used.
Today it is recommended that you download and install the MacOS
Unified Application.

The drivers written by the Prolific company have dropped support for
the older PL2303 XA chip that many generic programming cables use. To
get around this issue with Windows you can simply download, install
and select the older Prolific v3.2.0.0 driver. It isn't that easy with

What I did here to get around the issue was to purchase a Prolific
driver from a 3rd party developer (https://www.mac-usb-serial.com/).
The driver is not free, but it has been discounted 42% for quite some
time for €6.90 (which was $9.11 when I purchased it).

I don't have an FT-65R.
