I don't know Mac. My friend can't go anywhere online. It says the certificates are invalid or something in both Chrome and Safari. She mentioned she did an update. Just called her, she has 10.8.5 and just did 3 security software updates. So what/where setting does she need to fix? Or was something wrong with the Apple updates she did?
