A total re-write was required (and I mean total) for Mac OS X. This was a very different operating system from Mac OS 9. And Spell Catcher 8 was not a product that could be "Carbonized" so that it worked on both OS 9 and OS X - the core technology it used was totally yanked from OS X.

I never actually saw a Spell Catcher X box, and I'm not sure whether one actually existed. This image is lifted from the pdf of the manual. All the others here were scanned from actual boxes I have on my shelf. Maybe someone reading this can enlighten me...

As you probably know, Casady & Greene closed their doors in July of 2003. Unlike the other publishers we've been with, they made an extra effort to ensure that the rights to the products they published were returned to the developers. This meant we could start selling it pretty much right away, and that it wasn't tied up legally or financially by any C&G shareholders, creditors, receiver, or bankruptcy court. We owe them huge thanks for that.
