Google will be releasing the official non-beta version of Chrome Web browser on Mac’s OS X in November. However, they won’t be releasing the 32-bit version and would only have 64-bit available for Apple users.
According to a blog post from Google: “Unlike on Windows, where Chrome is available in both 32-bit and 64-bit, on Mac, Chrome will only be available in 64-bit with version 39 and after. As a result, 32-bit NPAPI plugins will not work on Chrome on Mac version 39 onwards.”
