Query: outdated software

CAUTION: Little Bear: Preschool Thinking Adventures (Jewel Case)is NOT compatible with modern Macintosh operating systems. For Macintosh, you must be running very old "Classic" software for this title to run. I suspect the same is true for Windows. I bought this for my two boys. I inserted the title into my Macintosh, running OS 10.5, and discovered that Little Bear only ran on computers running VERY OLD operating systems. Beware!!!
