I have Mid 2010 MBP 13" 2.66Ghz CPU 8GB RAM Nvidia GeForce 320M 256MB graphics with Yosemite 10.10.3 and all updates installed.
I cannot browse to any site using https after the upgrade neither Safari Firefox or Opera. This problem is nothing to do with my internet connection 50GB fibre broadband as I can connect to all these sites using an old iMac with Lion 10.7.5 and my iPhone 5S using the same network. I am using OpenDNS on an Apple Time Capsule as my rooter.
So, I tried all the suggestions "google" has to offer and none of them worked, except the suggestion that the Geotrust/Equifax Root Certificate was dropped from the Root Store braking a number of HTTPS websites. - Martin Heller InfoWorld.
I followed his directions to download the certificate and install with the necessary trust settings. It worked and so I thought the problem was solved but no the following day I am back to square one, although the certificate is there the HTTP sites "Facebook.com" and a secure connection to a school's intranet bring up " a secure connection cannot be established because the authenticity of the website could not be verified" or "Safari cannot establish a secure connection to the server".
I finally tried a clean install of Yosemite on a spare Evo 840 SSD using a thumbdrive installer I prepared when Yosemite came out. This did allow me to use Safari to view the HTTPS pages UNTIL I used migration assistant to recover my account settings (I deliberately didn't migrate and Safari settings). So what's going on and how do I troubleshoot the problem!!!
