I can see why you'd do that, but it's not in your path at single-user boot AFAIK, which means (l)users would have to type /usr/local/bin/tcfix, which is just added hassle. I'm reluctant to put a "never ask again" box, because I really want people to have it installed, and people are (in my experience) reluctant to do things (even for their own good). Yeah, I had noticed seeing as I wrote that mail, and it was the only example in a Cocoa application that I've seen that is open-source.
