I just downloaded the PrintShop update and it works fine. I used the old Broderbund version for years prior to OSX and was happy when MacKiev did the OSX version. I've been using their OSX versions for a couple of years now. Their OSX versions are so much better than another company that has tried to port over some of the old software. MacKiev does a great job integrating OSX, such as accessing iLife apps. I also use their OSX version of KidPix Deluxe at school. The kids love it.. Keep the great software coming!
