Good news for Mac-addicted Google-fanatics, Picasa may become available for Mac users in 2009. According to an AppleInsider source, a new version of the software is currently undergoing beta testing.

Google had hinted towards the arrival of a Picasa client sometime in January, but this is the first of such rumors that confirms it’s in the works.  A release sometime in January 2009 is possible, since Google won't usually withhold software releases because of beta status.

Regardless, the Mac version of Picasa will undoubtedly provide competition for iPhoto.
