Hey guys, im getting a 9813 error when authenticating a lot of times, like syncing my google calendar and buying music on iTunes. I've traced the problem to a MISSING System Roots keychain. It shows up in the keychain manager, but it cannot be unlocked. In Keychain first aid, its says that the keychain isn't there! Please help, its getting really annoying, especially on iTunes. Posted this in macbook/ibook, realized it was in the wrong forum..
