The Gmail Notifier for Mac has been updated to incorporate alerts, not only from Gmail, but also from Google Calendar. Now called Google Notifier, the new application places two additional icons to your menubar. With it, you can set your preferences as to which email client you would use, notification of unread messages, and pop-up alert. These configurations are also available in the Gcal pane for calendar events.

The alerts themselves are are simple and clean; they show you the sender, subject and an excerpt from the email.

Please be advised that there have been reports about a bug regarding looping authentication requests, but surely, a patch is on its way soon enough. As always, we'll keep you posted on important Google Notifier updates.
