[chirp_users] Kenwood TH-K20 and Mac

The CHIRP website says it supports the TH-K2, so that is what I selected when I attempted to program my TH-K20A with my Mac, but it didn’t work. It would not download the data from the radio. I tried with both RT’s USB-K4Y and the FTDI cable, but no joy. Is there anyway to use CHIRP on a Mac to program the TH-K20A?

Thanks.
