We run an all mac platform, cut with a Summa, and use MacSign for cutting. There maybe a better option out there, but this was what we found.
I personally don't think it's great software. They want to upcharge you for the full version and the free version that comes with a Summa purchase has many features of MacSign blocked. They do offer a discount on their full product because of the Summa purchase for 30 days, but it's still not all that cheap.
All that said, we've made it work. We didn't want to run boot camp or have a stand alone
computer that required a double transfer for cutting purposes. And we like Apple. To us the offset is worth it. Hope that helps.
