Google will launch the official, non-beta, 64-bit version of its Chrome web browser for OS X in November, a few months after an early build of the browser was made available on its Canary and Dev channels.
In a blog post, Google stated:
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."
In theory, running the 64-bit build of Chrome on OS X should offer better performance for users compared to the 32-bit version. Almost all Mac PCs are able to run the 64-bit version of Chrome, so dumping the 32-bit build shouldn't be a huge issue. If you are an OS X user, are you planning to use the new version of Chrome when it comes out?
