According to Neowin, the release of Chrome for Mac was supposed to be in December 2009, and it looks like they will be on schedule. An interesting paragraph in the roadmap reads:
Now that we have an initial beta release under our belts, our goal is to fill in the missing features and release on a regular schedule. WinChrome’s track record demonstrates our desire to release early and often (4 major releases in about a year), so expect frequent releases that add needed functionality and improve the user experience.
So all you Mac fans who are eagerly awaiting the official release, there will be some good news in the near future. We will keep you updated as and when a stable release for Mac is available for download.
