Gmail Notifr is a free, open-source Mac app that checks your Gmail for you and sends a notification when new mail arrives. It lives in your menu bar and supports multiple accounts, so you can monitor both a personal and a work address at the same time without keeping a browser tab open for each one. Each account gets its own settings. You can choose how often the app checks for new mail, which browser should open when you click a notification, and whether you want sound alerts, pop-up notifications, or both. It also works with Google-hosted accounts (like a custom domain managed through Google), so it covers more than just standard @gmail.com addresses. The app includes automatic updates via a tool called Sparkle, and unlike Google's own notifier software at the time, it doesn't install background processes that keep running even when you're not actively using it. This is mainly for Mac users who want a lightweight alternative to Google's official notifier or who juggle several Gmail accounts and want separate notification preferences for each. For example, you could set your work account to check every five minutes with sound alerts, while your personal account checks every thirty minutes silently. One thing worth noting: the app is built using MacRuby, a now-discontinued version of Ruby designed to run on Mac OS X. Because MacRuby isn't included by default on some versions of OS X, the app has to bundle the MacRuby framework inside itself, which makes the download larger and increases memory usage compared to an earlier version of the same project. It requires Mac OS X 10.6 (Snow Leopard) or later on a 64-bit Intel Mac, and building it from source requires a specific dependency for securely storing passwords.
