New to Brill Kids

Hello! I’m a mom of four kiddos; 3 typically developing boys and one 4 year old girl with Down syndrome whom we adopted from Bulgaria about a year ago. I’ve heard a lot about Brill Kids and how amazing it is for kids with DS, so I’m considering giving it a go! My main question is this: can it be used on an Apple computer? When I looked into this program in the past, I believe that I saw that it can only be used with Microsoft computers. Is this true? Thank you! I’m looking forward to learning more and helping my daughter grow her vocabulary, speech and reading skills!
