It's fully Panther (Mac OS X 10.3) compatible, and now supports RAW files format from Canon 1D / 1Ds / 10D / 300D / D30 / D60... sorry Nikon fans.
Just tried it for a hour or two just now, it does give a better color and final image output than Photoshop 7/ACR or Photoshop CS/ACR.
Great for Mac user, thanks Phase One... but do us all a favor: USD/EUR 599 is very high price to pay!
