I recently inherited an MH MK2 and am a mac user. It took me a couple hours to figure out the cheapest way for my mac to talk to the cutter, but I did it! I am an AI user already, so making SVG files was no issue for me. I downloaded a software trial called Easycutstudio and got everything talking to each other. The trial is free to test out, the software is SUPER easy to use and most self explanatory. I am really enjoying learning more intricate pieces of it too. I grabbed a jpg online of some tentacles and traced them out in Adobe Illustrator, imported it into Easy Cut Studio, click on cutter, chose my machine, and BOOM! It started working!! I was so amazed at how easy all of that was, and it didn't cost me a fortune to get started!! Once I get really savvy with it, i'll post some snap shots of the software in action. But I had to figue out what was best for my mac, and I couldn't find a lot of options out there. Hope this helps other people who might want to pick up a used older model cutter and are mac users! Thanks!
