Oh, you didn't say Mac! lol. It looks like they released a Mac version last year, they have a free trial. You might also consider installing virtualization software so you can run Windows programs on your Mac. My DH uses VMWare.
From the Quilt-Pro website:
"Activation allows you to purchase and try-out Quilt-Pro risk free for 30 days. If you decide that Quilt-Pro is not right for you, you can return it during the 30 trial period, provided that you do not permanently activate Quilt-Pro. Once you permanently activate Quilt-Pro, it is non-refundable."
Hope this helps!
