How do I know / find out which address is associated with the File Vault?
when I first setup my new MacBook (MacBook Air (M1, 2020)) I used an @icloud address for iCloud activity and an @yahoo as an apple ID. I activated FileVault and selected the option to use iCloud to recover. A few months later I changed the MacBook to use the @yahoo address for both iCloud and as the apple ID.
Question: how do I know / find out which address is associated with the File Vault? And if it is the old @icloud address, how do I change it to the @yahoo address?
