FWIW, a patch file to update your FTDI OSX driver to the RT Systems cables I have. This should cover most common cables.
It would be a good idea to back up the original first, though.
cp /System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Info.plist ~/Info.plist.ORIG
Context (after installing FTDI driver) is:
patch /System/Library/Extensions/FTDIUSBSerialDriver.kext/Contents/Info.plist rtsys_cables.patch
This might or might not have to be run with sudo.
Reboot after and you should have access to the cables in CHiRP. If you have different cables LMK and maybe we can muddle something together.
