Note: On Mavericks you may need to unload the kext for the USB device before plugging in the Softrock:
sudo kextunload -bundle com.apple.driver.AppleUSBFTDI
Using the method above gives error messages, similar to:
(kernel) Kext /System/Library/Extensions/AppleUSBFTDI.kext/Contents/MacOS/AppleUSBFTDI not found for unload request.
Failed to unload /System/Library/Extensions/AppleUSBFTDI.kext/Contents/MacOS/AppleUSBFTDI – (libkern/kext) not found.
Reboot the computer. Run the command again. Ignore the error message. And then try plugging in the softrock again.
Tried some variations of the command…
sudo kextunload -b /System/Library/Extensions/AppleUSBFTDI.kext/Contents/MacOS/AppleUSBFTDI
But the following one seemed to do the trick (at least for now) even though it still gives an error:
sudo kextunload -bundle-id com.FTDI.driver.FTDIUSBSerialDriver
For a more practical solution, check the FTDI manual, if it makes any sense to you.

It appears that this may have the code needed to build a Max external.
