CNET is reporting that recent discussion in a Chrome mailing list points to an early December launch. We could be just weeks away from a beta version of Chrome for Mac.
The Google group update in question is light on details, but by requesting that developers update to support Browser Actions, it also suggests that a December launch date for a Mac version is fast approaching.
Google Chrome's product manager, Nick Baum, writes:
"The extensions team has been working hard to get BrowserActions ready, and
they're already working great on Windows and Linux. We've noticed that many
of you have updated your extensions to take advantage of the new UI. We'd
like to encourage the rest of you to do so as well!

Why make the switch now? The earlier you switch, the more time you will have
to polish your experience for our Beta launch in early December. We realize
this means dropping Mac support for a couple of weeks, but we already have
people working on that. If you prioritize the Windows and Linux versions,
we'll bring you cross-platform parity as soon as we can!"
