I also haven’t been able to output from FCP 5.1.4 using the Intensity Pro via HDMI since the Apple update. I’ve updated the drivers to version 2.0, but still no go. Another thing I’ve noticed since the Apple update is that my system is no longer recognizing the additional RAM I have installed, only recognizing the original 1GB Apple RAM. I’m using a Mac Pro 2×3 GHz Dual-Core Intel Xeon.
