I just got The Learning Company software Reader Rabbit - Learn to Read with Phonics - 2 disc set. I have a set that says Windows & Mac, and I installed this on a Mac Pro running Snow Leopard. It didn't give me an installation error, but the game will not play and won't even load. The system launcher will come up, but no dice on the game itself. Any suggestions? I'm entertaining my grandkids - and so was planning on a bit of help from this software with the two pre-k kids!
