Are you finding that post updating Mac OSX now in the default Mac Mail client you can't launch Chrome? I got in touch with support and interestingly they push you to try with Safari. Great browser and at the moment I am now using this as a default. Why? Because I really love opening links from email. It's not that links from chrome didn't open it's very awkward to get the url and do it as well.
So it's not a fix if you like Chrome. Perhaps it could be a Chrome issue. Would like to see the comments you have on it.
