OS 10.5.8
I thought I would open keychain out of curiosity and I see there is a couple of items which says "This root certificate is not trusted" I looked at apple support and it said NOT to delete them.
They are: com.apple.kerberos.kdc & com.apple.systemdefault
I believe the first one has something to do with p2p which I
did use several weeks back (but not now)
I have never used keychain. Can someone please elaborate?
Should I ignore any future such notices?
