Will the Online version of TurboTax 2017 run with a Mac running OS X 10.10.5? Presently, TurboTax will not open.

I downloaded the online version and this version also failed to open due to the outdated OS X

It may be the version of OS X 10 that is causing the problem running Turbo Tax on your Mac.  You may also want to try using a different browser like Chrome instead of Safari to see if that solves the problem.

Please reference the overview of Minimum System Requirements for  2017 Turbo Tax Mac Software for both CD Download and Online Versions in the links below.
