Most emb software is written for Windows OS, but Embrilliance is compatible with Mac, and the people there are wonderful to work with if you need assistance. I upgraded to Win10 and could not transfer my Thumbnailer (love this program for seeing images of my designs) I emailed the company, they called me within an hr and proceeded to take over my computer via internet..he not only installed the program, but updated it as well. I've heard many good reports about the company. You should be 'good to go' with software compatible w/Mac.
