Nope, but I haven't tried running CGMiner or BFGMiner under sudo just in case it's a permissions issue like it was on the Raspberry Pi.  I may try again at some point, but since running it on the Pi was the end goal for me anyway, I don't really want to rock the boat too much.

When you do get the firmware updated and working again, let me know if running CGMiner or BFGMiner with sudo privileges works for you on the Mac.
