What if I don't want to upgrade my Mac?

TurboTax 2018 for Mac requires OS X v10.12 (Sierra), so if you don't want to upgrade to High Sierra (or later) you can use TurboTax Online for your 2019 tax-prep needs.

Next year, TurboTax for Mac will require 10.13 (High Sierra), so if you've been thinking about upgrading your system, now might be a good time to do it.
