Keychain is OS X’s database of passwords and keys used when retrieving email, connecting to Mobile Me (Formally .Mac), or anything that contains auto sign-on. We take the Keychain for granted and usually don’t even know of it’s existence. However, there’s one error that people keep asking me about: Error -2147415734. Keychain Error’s can be a huge pain, however this entry will explain how to fix the problem in a few simple steps.
- Locate the Keychain Utility in your Applications directory under Utilities.
- Launch Keychain Utility.
- Look for the fields whose Kind is “.Mac Password.” (Unless you have changed the default Keychain configuration, it/they will be located under the “login” keychain).
- Select and remove the fields by pressing the delete key on your keyboard.
- Confirm the deletion.
- Close Keychain Utility.
You will have to re-enter these passwords next time they need to be used (checking email, syncing to Mobile Me, etc.) and they will be “re-stored” in the Keychain.
Note: You may need to click the lock icon (in the upper left on OS X 10.5 “Leopard”) in order to make changes to your Keychain by authenticating yourself.
Huzzah! Problem solved!
