I have a macbook 2008 with 10.6.8 and have cloned everything to an external drive. When I hook up the external drive to my macbook air with 10.11, however, I can't access any of the keychain data from the 10.6.8 drive. How do I transfer the passwords from 10.6 to 10.11 keychains? Right now, I'm entering a few important passwords manually. Thanks.
