Hi DJ, I have a great intrest in robotics, but have never really done it, except for LEGO Mindstorms. But, I like remote control over programming. So, I surfed the internet and recently discovered EZ-Robot and been spending some time putting together a plan for my first robot. Then I thought of the downloading for ARC, and noticed it "Requires Windows XP, Vista, Windows 7 or higher" and in the FAQs, it says "EZ-Builder will run in Parallels in Windows on a Mac but not in OS/X." What does that mean? My family only has Macs now, so how do I get ARC? If not, can you recommend another program that runs on Mac and is compatible with the EZ-B? I appreciate taking your time to read this.
