So I'm trying to get my wife set-up on her new Mac, and everything works great...except you, Gmail. What's your problem? Supposedly you love Mac. And yet when she tries to do the most basic of things, you feign ignorance. I mean honestly, what's up with that (and that)? Unless of course your answer is, "we support IMAP," and you want me to move her off your app. I'll do it; don't think I won't!
It's time to grow-up and learn to speak some basic Mac.
