Then I opened the package. Guess what? Yes, it's the Windows version. At least the case is completely reusable.
I still plan to get TaxCut for the Mac...but good grief, people, can't you check your registration records enough to see that I have never bought the Windows version, and either save yourself the expense of sending me the coaster, or send the Mac version instead? They don't even have any info on the CD as to how to get the Mac version instead.
