For reasons I am not sure, years of saved WiFi passwords are on my Mac under the System keychain, meaning they are not syncing to my iPhone over iCloud Keychain. I cannot figure out a way to move these items to the Local Items keychain, which is the iCloud Keychain.
- Dragging and dropping doesn't work.
- You cannot export a keychain item unless it's a certificate+key pairing.
- Manually creating a keychain item does not work, as macOS adds an Airport permission to WiFi items that I cannot manually duplicate.
