I am using Yahoo as my search engine on Safari. I cannot determine the version of Yahoo. I want to upgrade to Yahoo 11 if possible. My Wife is having problems with her Yahoo after upgrading to OSX El Capitan 10.11/3 I thought an upgrade of Yahoo may be in order. --- Post Merged, Jan 30, 2016 --- Please ignore my post ! I just realized my "Search Engine" is Safari not Internet Explorer.
