Picasa for Mac released at Macworld

Google released Picasa for Mac that brings all of the advanced sharing and sync features of Picasa to the millions of Mac OS X users who use Picasa Web Albums — such as non-destructive editing, and the ability to keep track of photos anywhere on your hard drive, then automatically account for new images as you add them. To run Picasa, you'll need an Intel-based Mac running Mac OS X 10.4 and above.
