Get your taxes done using TurboTax

They just updated the FAQ about 3 hours ago after I submitted it as a bug - the FAQ did not previously mention the admin requirement, which in my opinion is a cop out, since it's easier to add a line to a FAQ than fix the obvious software problem.  An "uncaught exception" is a software error and has nothing to do with the unidentified developer certificate.    The FAQ is also misleading since it says from 2014 on, but 2014 & 2015 both open correctly in a non-admin account (at least in Yosemite - I did not try 2014 & 2015 in Sierra).
