When I bought my Viking my dealer told me that it would not talk to my Mac, that if I wanted that program it would cost $2800.00 and he never bothered to tell me about the additional software that I needed. My DH had an HP so I tried to load it and the new software didn't like my DH's computer, which turned out to be okay since it was too far away from my machine. So I ended up buying a new laptop from Costco since it was way less than $2800.00 that would take the new program. Even though it has cost me a lot more that originally anticipated I am still happy I got the embroidery machine.
