Exporting keychain items to use in another password manager
when I unlock my keychain on my MacBook Pro Sierra 10.12.6, and select an item the "export" in File menu is grey. Should I be able to export items i.e.. password / login information ?
No good way, unfortunately.
Closest way to view a decrypted list of passwords is via Safari, of all odd paths. Safari Preferences can show passwords, and there’s a button over there to decrypt and show all of the passwords.
As for other options:
