It looks like Techcrunch really did scoop the story earlier this year when they caught a Google employee admitting that they were developing Picasa for Mac. AppleInsider has now learned that Google is internally testing the software but does not predict a release date. From the write up:
Long the domain of Linux and Windows users, Google’s Picasa photo management tool is currently being tested for Macs, AppleInsider has learned.
People familiar with the matter say the search engine giant has just begun internal beta testing for the Mac-native version of the software.
While its proximity to a final release is still unknown, Picasa for Mac would serve as one of Google’s few fully offline Mac apps and has often been one of the most conspicuous omissions on Apple’s platform from a company otherwise known for its cross-OS friendliness in programs like Google Earth and SketchUp.
