Wow, the update did make a speed difference for me - for instance, when it came up with an error (for mail to accept my keychain), the message popped up, and there was little lag between when I said always allow, and when the second box popped up. Not bad, hopefully this update will fix the screwy issues I have been having with Illustrator. And hopefully my first impressions will not change! Onto the question: I used the downloadable updater. Should I still run the pre-binding command in Terminal? Thanks! John Pariseau
