Query: very outdated software

I purchased this (and other) software because it was described as bring compatible with the mac OS. Unfortunately it is only compatible with mac OS 9. The last time that this OS was distributed was nine years ago. So the software is unusable on any current mac, which means that our household cannot use the software either.A waste of money that could have been avoided with a more accurate product description.
