UR44 - Mac Os 10.6.8 compatible?

Hi there,
I’m very interested in purchasing UR44, but have question - is it compatible with Mac OS 10.6.8?
I know from my experience that some 10.7 only software runs under 10.6.8 without hasle (i.e NI Komplete).
I downloaded UR44 drivers and software package, installer had let me to install software package my iMac 10.6.8 without problems, but of course I got no device to check if it works.
I appreciate any help.

Really, nobody knows? So it’s better to buy MOTU?
