Okay, so, I have got a windows desktop now (found an old PC). So now, my next problem is, I now need an adapter for the coms lead to a USB as they are the only ports I have available.

Hey Guys, I am a very new, newbie here and do need some help (by newbie, I literally mean my first Heat Press machine arrived yesterday and I ordered my first Vinyl Cutter today). I have ordered the MH721, now I have read about how it's not amazing etc - please leave the 'upgrade' comments out of this as that is not an option. Since I ordered it and done some research and saw that a lot of people were struggling to connect it to a MacBook. So, here's what I need help with. - What is the best software to cut with on a Macbook with the MH721. I ideally need this to be free, a monthly subscription or very cheap (I have heard about SignBlaze being free?). Again, I don't want any expensive comments.. I am on a very tight budget. I just want a software I can import my designs into and cut. - Are there any complications connecting the MH721 to a macbook? Will I need anything other than the standard lead? It is second hand, it comes with the cutter, power cable, coms cable and installation disk. Hoping someone can help me. Thanks!
