Problem with "login" keychain
I am running 10.11.5 on a 3 year old iMac. After upgrading to El Capitan a few months ago, I started having problems when trying to login into my Admin account. I kept getting asked for the "login" keychain password. No matter what password I entered, it didn't work. There were updates over the weekend, and now I am having similar problems with my regular user account. These are the messages: "Messages Agent wants to use the "login" keychain." "accountsd wants to use the login keychain," "com.apple.iCloudHelper.xpc wants to use the login keychain" and "AppleIDAuthAgent wants to use the login keychain."
In addition, the Mail app no longer has my password to get my email. That's odd.
I have not chained the login password recently. So what can I do to make these messages go away? Thanks.
