It appears that you are not selecting the correct port. The "PL2303" would indicate the port being choosen is attached to a device containing a Prolific chip, not an FTDI FT232 chip.

You shouldn't need to install a driver for an FTDI chip based programming cable. The native Apple FTDI driver should work and is recommended. The port for an FTDI FT232 chip would look something like the following (the suffix will change).

/dev/cu.usbserial-A6020QSO
/dev/cu.usbserial-AH03HQ2G
/dev/cu.usbserial-DN00RXF8
/dev/cu.usbserial-DN00V4ZI

If you are actually using a programming cable with a Prolific PL2303 chip, then it is almost 100% likely to be counterfeit. To work with that type of chip, you must purchase a driver from a 3rd party for it to be compatible.

See this "issue":https://chirp.danplanet.com/issues/8559#note-9 from the day before where a similar problem with a Prolific type chip was resolved by using this 3rd party driver.
