just found this thread after a bunch of searching, I have a cMP with macos 12.4 w/ OCLP, iSight on 1.0.3. My iSight flashes green for a bit when i plug it in but no audio or video. As I understand it, the current 'fix' for Monterey/Big Sur is to use a TB2/3 to firewire adapter? Any progress with getting the built-in FW400 ports to work?
