I know nothing about OSX either, but:
drivers for an ordinary FTDI chip, like the one in the AXE027 cable, are up-to-date and readily available from the FTDI site.
To use them, you just need to change the PID of the FTDI in your AXE027 to the standard 6001 with FTPROG (also available on the FTDI site). You might need a Windoze computer to do that.
