Google has released a beta version of its Gmail Notifier software for Mac OS X.

"The Gmail Notifier is an application that alerts you when you have new Gmail messages. It displays an icon in your system tray to let you know if you have unread Gmail messages, and shows you their subjects, senders and snippets, all without your having to open a web browser," the company reveals.

Greg Miller, the Google software engineer who built the software, promises more OS X software from Google, saying: "Though this is the first, it won't be the last native Mac application that Google delivers. So please, Mac users, stay tuned!"

Google engineers are given one day per week to work on personal projects, so Greg Miller used his time to create the application, he revealed.

"I'm a Mac user. Most of my friends are Mac users. After a little coaxing, most of my family are now Mac users. So I decided to spend my time here on Gmail Notifier for Mac OS X."
