I have this problemn too, reported it several times. It seems that Mail.app is unable to connect to the Google IMAP server. If you use the Connection Doctor, you will see the SMTP server works, but the IMAP doesn't. As you say, the iPhone works fine, so something's wrong on Mail.app. Very frustrating, as even restarting Mail.app doesn't help.

Thanks for your note. So far quiting and restarting Mail brings it back to life but only for what's been missing up to that point. Doesn't keep pulling in gmails after that.

Yes, I found that works most of the time, but just today after replying to you, even stopping and restarting didn't work. I rebooted the iMac and then it worked. Absolutely nuts. Can't believe we're here months after Mavericks release and Mail still doesn't work.
