What OS operating system will be required for 2018 Turbo Tax

[docsteveca]

Currently using OS El Capitan.  Will this operating system work with the 2018 turbo tax program?

No, El Capitan won't work. You will see reminder messages in the program that you'll need to upgrade for next year.

I just got a download link for TT Premier 2018 and installed it on my El Capitan machine and it seems to work fine.

Looking at turbotax 2018 on Amazon it says that it works with El Capitan.  Sure hope that's true!

Below are the minimum requirements for TurboTax Federal 2018 software installed on a Mac computer.
Processor
    Multi-core Intel Processor with 64-bit required.
Monitor
    1024x768 screen resolution or higher.

RAM
   2 GB or more recommended.

That does not mean that it won't run in earlier systems, just that if might not run properly and won't be supported in earlier systems.
