How do I migrate my Keychain's "Local Items" to a new Mac? After preforming a Mavericks-Mavericks migration using Migration Assistant, I have a "Local Items" Keychain on my new machine in which many (perhaps most) items are out of date (using old passwords), and some are missing altogether. While I have access to a copy of the entire contents of the ~/Library/Keychains/ directory from my old machine, which presumably contains all the information I'm missing, I see no way of importing that information into my new machine.

How can I import the "Local Items" from my old Keychain into the Keychain on my new machine?
I just managed to get my keys to my new mac (this only works if you still have access to the old Mac and can boot it up):


(on the old mac) Remove your current user's password
Create a new keychain (without a password)
Copy all keys in "Local Items" to your new keychain
Copy the keychain to the new mac
(on the new mac) Remove your current user's password
Add the new keychain file
Copy all keys in the new keychain to "Local Items"
Delete the new keychain
Don't forget to set a password again after that


It's a bit annoying as you have to click "Allow" for EACH item in the keychain but well, it's the only thing I found that works.
