If you need the Home & Business personal version for Mac for Schedule C income, then you don't need it. Premier will work. All the Desktop programs have the same forms. You just get more help and guidance in the higher versions.
If you need to file a separate Business or Estate/Trust return you can not upgrade to Business. You have to buy Business separately. And you will still need a personal program to do your personal 1040 return.
AND Turbo Tax Business is not available to do online or on a Mac. You can buy the Window's version here. And you can have both TT Business and TT Home & Business (or any personal version) installed on your computer at the same time. Buy Turbo Tax Business here
