You can probably run the Windows Business program on a Mac using a Windows Emulator like Parallels. But you would have to buy a copy of Windows to install in it. Google Windows on Mac to get articles on the various options
One of the other users posted this, There are 4 popular products you can use: Parallels, VMWare Fusion, Oracle VirtualBox, or CrossOver. The first 3 require you to also buy a copy of Windows. The first 2 cost $50-80, the third is free. CrossOver also costs about $50-$80 but does NOT require you to buy Windows.
If you don't already have these programs it may be easier and cheaper to use a local tax professional OR just get the forms from the fed/state websites and fill them in manually.
