BTW, if you have an older Mac, another option is to install Windows 10 using Bootcamp or Parallels and run the PC version of TurboTax. If you have a MacBook Pro, Air, Mini, or iMac made in 2012 or later, you can install Windows 10. And Windows 10 should be supported by Intuit for at least a few more years.
