You must be within a day's drive of Cupertino.  Don't most Mac users have their computers set up to run Windows programs also?  Part of the fun of being a tech snob is complaining about how the minority must stoop to using a bridge to lesser systems that for some reason (like price) are still popular with the majority.  I looked up on Wikipedia the latest market penetration for Apple:

"For desktop and laptop computers, Microsoft's Windows is the most used at 69%, followed by Apple's macOS at 17%, and Google's ChromeOS at 3.2% (in the US up to 8.0%), and desktop Linux at 2.9%. In addition, 5% is attributed to "unknown" operating systems - which are likely forms of BSD or obscure varieties of Linux."

I don't use organizers and most of my clients wouldn't use a computer for it anyway. But if Apple compatibility doesn't add to the price of my software, I don't care of Intuit provides it.  I fear, however, that it would.
