Summary: scanner is just barely compatible with panther. Useless software. All the updates available won't make it run on Epson software. Be prepared. Only scans to Photoshop. Many hours spent setting up. Three calls to Epson. At one point I was told I didn't have enough memory and I have 1.25 Gigs! Stupid scanner - real hog. Dissappointed. Gonna try the PS solution - let you all know.
