Icom IC-9100 digital modes over USB setup guide
Craig (W1MSG) recently converted to OS X and has drafted a guide to get the Icom IC-9100 working with Digital Modes (specifically Fldigi) on a Mac.
This guide can also be used to get the IC-9100, and likely other similar rigs with internal USB connections, working smoothly with any OS X amateur radio application using only that USB connection. He reports success using MacLoggerDX, MacDoppler and Flrig over only the USB connection in addition to Fldigi.
The IC-9100 for Digital Modes on a Mac guide can be downloaded here.
Thanks, Craig, for sharing your experience with others!
