Should I be able to use the software with 2 different radio’s? I can’t confirm or reject if it is the cable. I have tried to install a separate instance of Chirp but I get the same error message “could not open port /dev/cu.usbserial-RT0UYFJC: [Errno 2] No such file or directory: '/dev/cu.usbserial-RT0UYFJC’ yet this is the same connection on the FT60r. I am also using this on a Mac Book high Sierra

Most likely the programming cable for the FT7900 has a different brand
of USB-to-TTL UART chip. The device driver for this cable is either
not installed or incompatible. This happens quite often with Prolific
type chips. Most are counterfeit and the latest Prolific device driver
is intentionally incompatible.
