You probably need to install the driver. See http://chirp.danplanet.com/projects/chirp/wiki/MacOS_Tips
Use System Information -> USB to find your cable in the USB device tree. If it's a Prolific device, you can try the open source driver mentioned on that page, although the one at http://xbsd.nl/2011/07/pl2303-serial-usb-on-osx-lion.html seems to get better press.
If it's an RT systems cable (probably FTDI inside), get their driver, see above reference.
If it's a generic FTDI cable, get the driver from the FTDI website at http://www.ftdichip.com/Drivers/VCP.htm
I was just going to point you at the above Chirp page, but that looks to be in need of some serious update.

Greetings: Brand new to CHIRP and have just cloned my FT-857 (in Windows, running Parallels on a Mac).
I'd really like to figure out how to run it natively in OS X and have installed the Python package and the latest CHIRP build, but can't get CHIRP to see any ports other than a couple of Bluetooth entries in the ports list. I'm also fairly new to Macs, so am not sure how to manually address the port from within CHIRP.
Can anyone point me to useful startup documentation for Mac users (assuming my radio interface cable is good, since it works well for me on the Windows side)?
Thanks Matt
