Viking is launching a new embroidery software just for Mac users. It is called Tru Embroidery. You can go to truembroidery.com to check it out. If you preorder you get a free gift.
I don't have a MAC but have heard many times on here how MAC users need good software too. I hope it's all that Viking puts into the 5D Pro, which I love by the way. Even though I'm new to it all, I'm having a good time with it.
