2018 Turbo Tax will not launch on 10.14.3

I initially installed turbotax 2018 on Mac OSX 10.14.2. Install went fine, program verified, icon in menu bar...but it won't launch. Updated to 10.14.3 same problem. Tried everything, including download wifi and direct ethernet cable as well as install in safe mode. Turbotax customer support did not resolve problem. Also, Turbotax 2013-2017 will not launch either. 2008-2012 works. Any other advice?

iMac 21.5" 4K, 10.14

I am running TurboTax 2018 Deluxe+State on a Mac mini 2018 (10.14.3). I installed under 10.14.2. No problems so far. As a matter of fact, I just launched TT (while reading your post) and got the latest updates installed and restarted. No issues. I have the Mac download version that I bought online from OfficeMax (I think) a couple of weeks ago when I snagged the $39.99 deal. Good luck.

Download and run Etrecheck.  Copy and paste the results into your reply. Etrecheck is a diagnostic tool that was developed by one of the most respected users here in the ASC and recommended by Apple Support  to provide a snapshot of the system and help identify the more obvious culprits that can adversely affect a Mac's performance.

I'm currently working with Apple Tech Support on the problem and we ran a full diagnostic. I will post again once Apple gets back to me, which should be in a few days. Working with support, I also created another user account with admin permission and Turbotax loaded and launched on that one. So, it does not appear to be a Turbotax (Intuit) issue. I guess I have the same temporary solution as you. This iMac profile was a migration from my previous iMac (2008 running Sierra) via Time Machine.
