Google Notifier for Mac: Gmail, Gcal alerts
Google has expanded and renamed its Gmail Notifier app so that it includes alerts and reminders from Google Calendar.
The revised app, now called Google Notifier, adds two icons to your menubar:

In the Preferences you can set which email client to use for composing messages, whether to display an unread message count and to receive pop-up alerts.
The Gcal pane offers similar options for your calendar events.
The email alerts are elegant and give you the sender, subject and a brief excerpt from each incoming email:

UPDATE: As Arsen points out in the comments, the new app has some rough edges. The endless loop of authentication requests can be short-circuited by turning the Gcal notifications off. Not ideal. Rather defeats the point of the updated app. No doubt a fix is on the way.
Google Notifier is freeware and is available from the Google site

Downloaded it 2 hours ago, experienced Google MADNESS, searching for a solution and found that.
Here is a specified routine after Installation and Launch
The authentication box pops up – filled – Click Sign In – Spin – Disappear – Pops up again – Click Sign In – Spin – Disappear – Pops up again – repeat …….
By clicking the cancel button does not stop this being happening, it only delays it..
Solution: disable the Google Calendar notification…..Nicely done, Google.
Another frustration about this new Notifier: if you click the very top (aka, edge of the screen) of the notification icon on the menu bar, the menu won’t show up. You gonna move your cursor down a little bit and click to let the menu appear. Why is this frustrating? I used to move my cursor strait up to the very top and search the menu bar horizontally for the icon I want to click.
This new notifier is driving me crazy..

Yes, that is annoying.
Thanks for the fix, although it rather defeats the points of the new app. Hmmm…. I thought that everyone at Google was incredibly clever. I wonder how this happened?

3. I am always concerned about not placing the icon in the middle vertically in the menu bar
4. it checks for new mails every two minutes, impossible to modify, same as gmail notifier
5. impossible to kill the notification
I believe this cr-app qualifies for a mention in the we-hate-software blog

The continuous GCal requests for the username and password are annoying. I wonder how something like that got through? I know it’s a beta, but come on. :)

Do we think htat it was actually tested on mac?

How could they release it without noticing this bug?
Are the google guys smart enough that they can just write code without running it?

It would be a criminal act to release Mac software that hadn’t been run on a Mac at least once. :)

I have reported this to Google

If you hear anything back from them, I’d be interested to know what they say.

If you activate your Google Calendar, it won’t ask for authentication every 2 mins

Hi Jessica. Thanks for the comment. What do you mean by “activate your calendar”? My calendar looks pretty active to me.
