Can turbotax Premier 2017 run on macOS El Capitan version 10.11.6? It appears to load from the CD successfully, but when opened, checks for updates and shuts itself down.

I am running macOS 10.11.6, 2GB memory, more than 100 free GB on hard drive on an older (pre-late-2009) iMac.

I read the recent FAQ "TurboTax 2017 for Mac OSX 10.11.6 Error: 'TurboTax quit unexpectedly' after the most recent update," and then followed the instructions to uninstall turbotax Premier 2017 and reinstall it to get the most recent update. It updated. I clicked on the upgrade dialog box "Install and Reload." 

Then when I try to open turbotax2017, I get a dialog box which says "Please wait while we verify everything is up to date" and then it seems to just shut itself down and the turbotax icon disappears from the dock.

Help please - I've been using TurboTax successfully on this iMac for many years and want to do so this 2017 tax year. Thanks!
