GROSX 0.1 for Mac was available to download from the developer's website when we last checked. We cannot confirm if there is a free download of this app available. This free Mac app was originally created by Eli Dourado. We recommend checking the downloaded files with any free antivirus. The software is included in Internet & Network Tools.
From the developer:
GROSX (Google Reader for Mac OS X) is a small program that integrates Google Reader into OS X. GROSX uses the hooks in OS X to subscribe to a feed in Google Reader. It also sends notifications through Growl when new items arrive in your Google Reader account. Built with Universal Binary goodness.
