i don't suppose you'd be interested in giving a full account of problems and work-arounds setting up US-428, Logic and OSX ?
are you doing it in Jag? any tricks? caveats ?
too early to say... I just got the upgrade a few days ago.
There's a lot of things OS X does in the background that I'm going to have to learn about. They may or may not have anything to do with audio performance, but it's a whole new thing. I'm also recording to the iBooks internal disk (not the fastest in the world), and I know that the OS uses a form of virtual memory. I wonder what effect that has on disk access.
Lot's of questions...
Thank god I'm not doing this for a living.
