Jeremy,
With the new HD install I upgraded all drivers. Didn’t use any old ones at all. Apple now thinks it might be the ram but personally I’m thinking hardware at this point.
I’ve got some Apple ram I can use but I’m willing to bet it will KP again. The 16 GB or ram is from Ocz that was designed for Mac…or so they say. It’s worked great in the other 3 editors and also in this one prior to the upgrades to the OS and FCP.
