In Mail and iTunes I get the same announcement over and over again: invalid certificate, can't check the identity from the server. I'm using an iMac Lion 10.7.5. I would love to upgrade to Mavericks. But I can't get a connection with the Appstore either....

I changed the cerficate-ssl in Keychain. But with no effect. I hope someone knows a solution

iMac, iOS 7
