I've just put in a Sonnet Tempo E2P and a AJA Kona 3 cards in my Mac Pro. (13 gigs ram) Now its a nightmare. I'm not even sure if its the cards or the 10.5.2 update. I've had to reformat my main hard drive because of some uncurable b-tree problem. I've had to rebuild my system 3 or 4 times. I finally put in a terrabyte drive to use for Time Machine but even that isn't putting things back 100%. I've pulled everything out, I've put them back in one at a time. Nothing seems to matter. Suddenly Final Cut Pro won't see my Tiffen Filters and my projects are no good. I'm losing my mind. Every god damn restart has a whole new slew of problems from missing filters to desktop pictures that disappear on their own. Anyone out getting 'Vista-ed' likes this? I'm a Mac whore, but right now, with a video to get out, I'd like to kick someone from Apple in the nuts over this.
