Solved: Yes. 2018 will require OSX 10.12 or higher.

Will Mac OS Sierra still work with Premier TurboTax 2018?

I had to upgrade to Sierra (10.12) for 2017. Will Sierra handle the 2018 version of TT? 'High-Sierra' doesn't handle my web-services, so I'm unwilling to upgrade to it. If 'High-Sierra' will be required, I'll have to move to a different tax-program.
