I run Kona LHe 1.2.2 + OS X 10.4.6 + FCP 5.1.1 + QT 7.1
I have huge problems. The card stops working on my system at each boot-up. I have to shut down my computer remove all the cables and make my KL-Box powerless, replug and reboot every morning to get the card to work.
I contacted AJA support thru email 10 days ago but they have not even replied.
