I'm using a 15inch Retina (OSX10.8.2) and trying to see if I can daisy chain from my Fireface400 to MOTU.  I followed this instruction on the Apple site, but this is not for Mountain Lion.   Do I need to use ADAT to connect Fireface and MOTU, or would this not work at all?  (then I have to use two computers connected with UDP)  http://support.apple.com/kb/HT1215
