If you are truly asking about TurboTax Business, not TurboTax Home & Business, it only runs in Windows. You cannot install it on a Mac.
All versions of TurboTax for 2016 are no longer supported. If you are getting an error trying to install it, TurboTax support is not going to help you. And, as Critter-3 said, even if you could install it you would not be able to get updates or state programs.
