As anticipated, Google has finally released an official beta version of its Chrome browser for Mac. The initial beta version, termed Build 4.0.249.30, requires Mac OS X Leopard or Snow Leopard, and is only compatible with Intel-based Macs. In addition to the Mac release, Chrome for Linux has also been promoted to a beta version.

Chrome for Windows launched as a beta version in September 2008, with Google co-founder Sergey Brin admitting only days later that the lack of a Mac version at the time was "embarrassing". At the time, he hoped that a Mac version would be available in only a "matter of months", and the company announced in January that it was targeting a Mac release for the first half of 2009.
