Quilt-pro has a software design package for mac. I have it and it is really great, plus they send you a new block each day that you can download into the software. They also have a foundation factory package for mac that has paper piecing blocks, many from Carol Doak. If you go to their site, you can see the video. Good luck with your mac, I love mine, they say once you go mac, you never go back. here is the link to their site.
