For what it’s worth, after installing Tiger yesterday, on system startup the Blackmagic Daemon goes into a crash/relaunch/crash loop. There appear to be two instances of the daemon running, one that’s stable and the other that keeps crashing and relaunching. The fix is to kill the stable instantiation, while stops the other daemon from relaunching, and then to remove the daemon from the Startup folder.
Best wishes,
