I have a MacBook Air, mid-2012, and had this same problem: I could get non-SSL websites to load but not SSL sites (those with https:// at the beginning of the address).


Three techs at the Genius Bar worked on the issue for nearly an hour, trying a variety of fixes, including cache clears, date-and-time check and removing most third-party software. I'd already verified and repaired disk permissions on the hard drive.


This is what appeared to be the problem -- an error in my Keychain configuration. We went to Finder/Applications/Utilities/Keychain Access/Keychain First Aid (who knew!). I entered my password, verified and then repaired. I had no idea Keychain had its own First Aid.


Might try it -- wouldn't hurt....

I have just installed Yosemite on my mid 2010 MBP, having the same issue. Can't access Facebook or Mailchimp. I've also tried Keychain repair, Cache Clear and Library Cache Clear, as well as uninstalling and reinstalling various updates of Java. This is on Chrome and Safari. I'm getting the battery replaced this week so if I can't sort it myself, I'll get them to have a look and come back here with their solution. Such a pain right now as I really need Mailchimp for work.
