Hi Steve,
Thanks, for your response. You are correct. I am now getting a message stating m2tech driver not found. I have one of the last OR4, if not the last, you built. I think (I am not super technical) the driver used for my OR: EM_Usb_snowleopard. Is there a way I can uninstall my driver and upgrade to Mavericks and still use my wonderful OR4?
Thanks, Gary
