Greeting to the group

I have been trying to help a friend out with his FT8800R and connection to Chirp. He is running a Mac Mini that I be leave is pre Intel. He purchased the dedicated USB to radio cable from a link on the Chirp web site. Here is the problem, he launches chirp OK, it recognizes his cable, he places his radio into clones mode, but he keeps getting an error message which states: "could not open port/dev/cu.usbserial-RTWHKYXO: [Errno2] No such file or directory: '/dev/cu.usbserial-RTWHKYXO'"

Any help would be appreciated.
