Yikes - it helps - and that's what I'm afraid of - to buy the EQ7 and not be able to run it on my mac because of glitches. My macbook in brand new but my windows version is old. I may try to upgrade my windows first...and I still would like to hear a success story by someone who runs it on their MAC without a hitch. I wish these companies would get with it regarding MAC's. I am a graphic designer and started working on macs when the screen was 6 inches big and B&W. 90 percent of the artistic fields work on macs - in my opinion - quilting is a huge artform and a billion dollar industry. They need to step it up. (I wouldn't dare try to run EQ on my work desktop MAC at home- I couldn't risk it) thanks for the reply!!
