If Deluxe worked on your Mac then all the versions should. But as I said above you really don't need to upgrade. Deluxe can do everything the Premier and Home&Business has. And you didn't need to buy another version for your return. The Desktop program can do unlimited returns and efile 5.
But now since it doesn't work you are stuck with talking to support. Or maybe a Mac user can chime in. @macuser_22
