When Google launched Chrome it was for the Windows platform initially. Google CEO, Eric Schmidt, has publicly stated the Google Chrome will be released in the near future for OS X but if you"re willing to use pre-beta software from Google then you can download Chrome right now.
Google has stated that the software "still lacks certain privacy features, and is not appropriate for general consumer use" which is a gentle reminder that the software is not complete. But, if you are like most tech enthusiasts and are willing to look past the flaws in the beta, then you will find a surprisingly stable build of Chrome that can be used for day to day web browsing.
The link to the download can be found below and it is a developer build but early reports are stating that it is the most stable release to date. If you make the dive into Chrome let us know how it is but don"t expect any quick bug fixes from Google as there is still time until the browser is ready for mass consumption.
