Sorry but Turbo Tax Businessis not available to do online or on a Mac.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 variousoptions.
WE NEED TURBO TAX BUSINESS SOFTWARE FOR MAC COMPUTERS. Apparently there is a need for it. Why can't Intuit create this for TT Business when it is formatted for the Mac computers on all the other Turbo Tax versions.?? IT MAKES NO SENSE. Most Businesses use Mac computers these days. I have been asking for this for years.
