Sharon,
I wanted to run Designer Plus and EQ7 on my Macbook Pro, so my son partitioned my Mac and installed Windows 7 and Parallels and put my Designer Plus and EQ7 on my Mac. I am not sure how he did it, but I can ask him this week.
Afterward, I found that it took a considerable amount of time and inconvenience to switch from one operating system to the other just to use Designer Plus and EQ7. Also, when I wanted to update antivirus software, etc, I had to do it on one operating system, then close that system down and open the other operating system and run updates separately on that. There are better ways to spend one's time.
Then thankfully EQ7 came out in a Mac version. I have updated to that.
He picked up a cheap, secondhand Windows-based laptop, installed Windows 7 on it just for Designer Plus. My Bernina dealer said this is what a lot of Designer Plus customers end up doing. Unfortunately, I understand there are really no plans to produce a Mac version of Designer Plus. I wish they would. There are a lot of Mac users out there.
