Safari wants to use the "login.keychain_2" keychain
I have hundreds of logins in a login.keychain copied over from an older Mac and renamed login.keychain_2. I have it placed in the proper folder in the new Mac next to the native login keychain. I’ve changed login.keychain_2's password in Keychain Access to the current Mac’s admin password.
However, Safari keeps asking me for the password to use it for every old site that I revisit. Sometimes (it seems sometimes but I could be wrong) that the same sites I'm visiting also keep asking for the keychain password!
In Keychain Access, I can double click a login item and change its Access Control, but there are hundreds of login items! Doing it for each one manually is no better than deleting all of them and letting my new Mac (new Mavericks, new Safari) save each one natively. This would be recalling and individually typing in hundreds maybe thousands of login names and passwords.
What else can I do?
MacOS 10.9 Mavericks
iMac, Mac OS X (10.7.5), and iPad4 iOS7
