I've installed Chirp (chirp-daily-20130301) on my iMac OX10 (Lion 10.7.5), but I cannot get it to read from my radio.

When selecting "Radio" > "Download from Radio", my two port options are

/dev/cu.Bluetooth-PDA-Sync /dev/cu.Bluetooth-Modem

Since I'm not using Bluetooth, I'm at a loss for what to do. Any help would be appreciated.

Radio is a Baofeng UV-5RA
