Hey Folks,
Just wanted to let everyone know that I recently purchased an MH 871-MK2 from US-Cutter and it is working perfectly fine with the USB connection directly from my
Mac Mini/OSX 10.7.5 - No serial converter needed. I basically installed the Sure Cuts A Lot software that came with the cutter. Once installed and registered, the SCAL software advised me that there was an update available, and I performed the update to SCAL Ver 3.047. In the Help menu on SCAL there was an option to install drivers for MH series cutters, which I did. I then rebooted my Mac. After the reboot, I plugged the USB cable directly from the mac to the 871's USB port, fired up SCAL - dragged a shape onto the layout screen, and hit the cut button - Sure enough the cutter came alive and plotted out the pattern perfectly happily.
hopefully things will go as easily for other MAC users..
Todd
