Hi Nathasia,
Unfortunately, BrillKids Learning Systems do not officially support Mac operating systems. You may refer to our system requirements in these pages:
Little Reader Learning System

http://support.brillkids.com/index.php/article/little-math-system-requirementsWhile we intend to do a Mac-compatible version of all BrillKids learning systems, it's not likely to be anytime soon.
We do have several users who worked around this issue by installing Windows on their Macs via BootCamp, Parallels or other similar software, and they have been using our programs on their Macs for quite some time now. However, we do not provide customer support for any problems encountered as the software is not designed nor tested for Macs.
Kindly have a look at these links for more information about Boot Camp and Parallels:

I hope this helps!
Cheers,
Kezia
