Upon startup my iMac has a popup that says: "talagent wants to use the local items keychain." New to me--can't get anywhere. How do I get out of this and get things up and running again?

I did option three only and it solved the issue for me. Thank you!

I had the exact same issue. I tried a half dozen things before I saw this post. I tried just #3, locking and unlocking the keychain lock and it worked for me. No more Talagent or messages agent logins on every boot up.

Same problem here on El Capitan 10.11.6, except it was another application mentioned in the popup (not taligent). I tried #3 and it worked. Lock and unlock Local Items, and then when prompted change the password to my new system/icloud password. I don't know why this isn't taken care of automatically.

This didn't fix the problem for me - macOS Sierra 10.12

I just started having this issue after updating to macOS Sierra.

I tried all these solutions already before reading this response.

1 - Keychain First Aid no longer exists in macOS Sierra

2 - I've run Disk First Aid many times, both after login and during reboot with command-R - no errors found, nothing to fix

3 - Locked/unlocked login keychain multiple times, didn't make a difference.

I've also reset the login keychain password to something different, then set it to the same password as my login password. No change.

Any ideas anyone?

Mac keeps asking for the login keychain password

Keychain Issues - Resolve see post by Kappy

Thanks, I'll post new in Sierra.

I've seen the other two links you shared, neither of which is precisely applicable in that the OS is asking for access to the "local items" keychain, not the login keychain. I listed my attempt to fix the login items keychain as a way of showing what I had attempted to repair this issue in case it had any effect but it didn't.

Further investigation showed the local items keychain is changed to "iCloud" when iCloud keychain is enabled, so my next step was to try turning iCloud keychain on/off but that made no difference either.

Upon startup I'm getting the following message:

accountsd wants to use the "login" keychain. Please enter the keychain password.

Nothing I try works and I cannot access information or apps on my MacBook Pro. Please help.

At the start of my mac computer disk top I get massage "accountsd wants to use the "local items" Keychain password" which I don't have it or I don't know what it is. Need help to get rid of this massage
