I encrypted some drives with
Disk Utility and set a password hint. This hint does not show on a different computer. It's embarrassing because those were backup drives and losing the computer means also losing the key to the backup.
However, I found out by chance, when I was doing a boot from a live USB, that hints for startup disk encryption do show their password hints, as shown in this example:
Could anyone confirm that password hints for drives encrypted with
Disk Utility are saved on the local computer and do not show on different drives, ideally with a reference?
And in which cases do encrypted drives store their hints, as in the startup disk example above?
Update: I am running
macOS 10.14.6. Here is a screenshot of the drive encrypted with
Disk Utility that does not show a hint:
I believe that I chose
MacOS Extended (Journaled, Encrypted) as the format in
Disk Utility.app for the drives that do not show a hint. Here is the result of
diskutil list with the two drives connected, one that shows a hint and is decrypted, the other that does not show a hint and is locked:
