No,  TurboTax Business is a Windows-only software program available as a CD or download. 

Is the cd downloadable to a Mac? I downloaded the home and business software cd onto my Mac and worked.

No, TurboTax Business is not available as a CD or download to a Mac. There isn't enough demand for it.

TurboTax has Home & Business for Mac and that is what you probably downloaded.

If you buy the TurboTax for personal income tax preparation, the CD it has both the Windows and Mac programs on it.  If you buy the Download you have to specify which download you want.
