Direct link to the DFU loader documentation, avaliable from the support pages of xmos.com:

Not having comfort or experience in developing software for OSX I found this task a bit frustrating but I was able to stumble through with various googles. The assumptions made by the documentation may be obvious to most here but:
First you need to install the compiler. This was helpful:
http://www.edparrish.net/common/macgpp.php
Modify xmosdfu.cpp to look for your VID & PID
make -f Makefile.OSX
I never discovered why but the application looked for libusb-1.0.0.0.dylib in /usr/local/lib
As is the application won't run.

Solution:
install_name_tool -change /usr/local/lib/libusb-1.0.0.0.dylib ./libusb-1.0.0.0.dylib xmosdfu
Now it works.
This can probably be pruned and packaged with a script so that it does the job without requiring too much confusing interaction from the end-user. It would be great to have some nominal GUI version of this app. that can be supplied with VID. PID in an accompanying text file. I hope something like that emerges.
