apaulsen444: I do not see a question from you, I answered the original posters question, they did not ask about Mac. If you order the CD it includes both the Windows & Mac versions on the CD. If you want to purchase the Download version you would check the Macintosh button on the Download TurboTax now screen which comes up after you click on the Buy Now button on the version you want.
