Korimichele,
For over 2 years we used Little Reader and Little Math on Mac, -- through running Bootcamp program, which is actually built in every latest Mac OS version. We had no problem whatsoever with it!
It was before BrillKids released Little Reader Touch for Ipad. So if you would want to run it on Ipad, it is available and my kids love the touch version
So, first of all -- no need to be disappointed! And secondly, welcome to BrillKids community. It is wonderful to have you here on the Forums, feel free to ask any questions and share your progress with your little one!
