Photoshop does.
You can choose to use either Adobe's stuff or Apple's. If you use Apple's, you can move stuff between Adobe apps and non-Adobe apps while maintaining consistent color.
(And color management support runs *deep* in OS X. Hell, even Mail supports it, which is nice when you're firing mockups around... to other Mac users, of course. I believe developers get it unless they explicitly say they don't want it, if they use Apple's image handling APIs.)
And from what I've seen, the fact that you can run mainstream desktop apps like Photoshop on the same box as all the *nix stuff is, in fact, a major reason, maybe *the* major reason, why OS X is doing so well in this market.
(Plus, I think particularly in the Rails community, there's a lot of emphasis on good design.)
It can, but there are some serious problems with that. One is that it obviously isn't available on the Mac...
I'm really not sure how true this is. Maybe big teams can still afford real separation of design and coding, but I'd hazard a guess that a majority of web work these days is being done by pretty small teams, or often by individual freelancers.
