Those messages look normal to me when I want to use apple's keychain for name and passwords when browsing.
In other words this doesn't look like a thing to fix.
I have problem when i want to start working on Mac then show these messeges direct and i should write password every once to be able to use programs.
Message is :
(Safari wants to use the "local items" keychain.)
please enter the keychain password.
(Safari,Accountsd,CallHistoryPluginHistory,CalendarAgent....... and other programs too)
There is someone can help me to fix it?
