- Make sure Google Chrome is your default browser. This program will probably break mailto: links if you have a different default browser.
- Download Gmail Mailto Chrome Handler.app, put it somewhere useful (like /Applications), and run it.
- Try clicking this mailto: link. If it opens a new message in Gmail, you're all done!
- If the mailto link didn't work as expected, open Mail.app, go to Preferences, and under the General tab, select Gmail Mailto Chrome Handler.app as your "Default email reader".
