I don't know where "xmasbaby0" gets his information, but as of today (11/26/2018) that 1899173 article that he references says NOTHING about TurboTax 2018 for Mac, only 2014-2017. I just inserted my newly-arrived "TurboTax Deluxe 2018" DVD into my older Mac running 10.6.8, and when I open "TurboTax Deluxe 2018.dmg" and then try to open "TurboTax Deluxe 2018.app" (the program itself) it displays an alert that clearly says that it requires Mac OS X 10.9 or later. If you want to find out the latest version of Mac OS to which your Mac can be upgraded, go to <a rel="nofollow" target="_blank" href="
