Wondering if anyone else experienced this issue with the latest version of 10.10.3 Beta. I just updated to the latest 10.10.3 beta (14D105g). As soon as I opened Chrome I received a warning that the identity of google.com couldn't be verified. Looking into it I found that the Equifax Root Certificates were not present in the System Roots section of Keychain. When I checked a Mavericks system the Root Certs were there so I copied them and installed them into the System Keychain. This fixed the problem but I wondered if anyone else had the same issue after updating.
