This is what I first used for OSX Lion
http://changux.co/osx-installer-to-pl2303-serial-usb-on-osx-lio/

It is an installer package but the installer is in Spanish. But if you
are familiar with how an installer package proceeds, you will figure it out.

This may also work for you, it does show the installer dialog in english

I connected the cable into a PC and found out that it was a prolific cable, so I just installed it and rebooting.
