Hi Rochelle, BrillKids software are only compatible with Windows systems. Right now we don't have Mac versions yet, but we do have a Little Reader Touch app (which is one step closer to the official Mac version of Little Reader).
Please see here for more details about the Mac compatibility of our software, and a workaround for installing our software on Macs (via Windows on Boot Camp):
