So... an update. I was able to boot via USB 2.0 to my Cloned System Drive, mount my server via Thunderbolt and Render to ProRes in a computer state that existed prior to FCPX. Thank you Carbon Copy Clone and my foresight to make a clone of my system drive. The renders were able to complete to ProRes for my deadline tomorrow. This still leaves me with a question of, how to resolve the ProRes codec on my seemingly corrupted system drive. I could always clone the system from the clone, but I'm hoping there's an easier way to manage it. I do have a ProApps Codec Update from the App Store I've been waiting to install until I was finished with my projects, do you guys think that might solve the issue? Just trying to be smart about it as I'm right in the middle of some deadlines...let me know your thoughts. Thanks!
Last Update - FIXED:
So, not sure what happened, I'm guessing FCPX / FCP7 introduced some wonkiness with the Apple ProCodecs Package. After running permissions on my server, YASU (Yet Another System Utility) Permissions Repair, I finally went and bit the bullet with Software Update -- usually not something that I do in the middle of something. Software update provided a ProCodec update specific to FCP X that appears to have fixed the problem. So yay me. Thanks for listening.
Thanks for sharing what worked for you.
