Will Safari 11.1 and OS X El Capitan support Turbo Tax for 2018?

[Opus 17]

El Capitan will not support the desktop version installed on your own computer, you will need Sierra or High Sierra.  WE haven't heard about changes in browser compatibility for the online version, but any browser that supports the encryption standard for the 2017 tax season will probably support 2018.
