Arduino adafruit pro mini serial port

I've been having issues with my mac recognizing serial ports. With my real UNO it works ok, but as soon as i branch out into clone boards there are no serial ports. I recently purchased a Arduino pro mini through adafruit (so they aren't clone boards) but it will not come up in the ports. Despite dowloading several drivers it still isnt coming up. What can I do?

The Pro Mini doesn't have any hardware to create a serial port. You need to use a separate adapter (e.g., FTDI cable) connected to the Pro Mini for this purpose. We need to know the details about that adapter.
