Yes - I did find that out - but if you have a program called parallels - you don't have to reboot. I was afraid to mess up my MAC too - but I did have the Parallels program and a copy of windows from my Embroidery PC and it seems to work - I haven't purchased the EQ7 yet - but was really curious if anyone is actively working with in on the mac and it's working without any hitches. Thanks for responding. If you know if your friend is doing that can you see if it's working well for her? thanks again!!
