    I just confirmed that I have FileVault enabled on my Mac but was not sure if I had used iCloud recovery or a recovery key. After some research I found the following:

    Assuming that your disk is APFS formatted, run the following command in the Terminal:

    diskutil apfs listusers /

    Then you need to check if it lists “Type: iCloud Recovery User” and “iCloud Recovery External Key” – if that is the case, then your computer thinks the recovery key is stored in iCloud.

    If I purchase a new iMac and with the setting up process with the computer would I use migration assistant to move all data from old to new, then turn on FileVault after the data successfully transferred. Or set up new Mac by following the prompts with out migrating the data first. Turn on FileVault, then use Migration Assistant to transfer data from old to new.

    Danny: You use Migration Assistant when setting up the new Mac. Read about it here: https://support.apple.com/en-us/HT204350

    Hello again Gary. You didn’t really answer my question. I know how to use Migration assistant. My question was really about do you turn on FileVault first in the process of setting up the Mac, before migrating the data or turn FileVault on after the data has been migrated.
    Thanks again

    Danny: If you use Migration Assistant, you are doing it when you set up the new Mac. Just follow the prompts.I believe it should ask you both about migrating and about FileVault during the settings up. Just go through the steps.

    What’s the difference between FireWall and FileVault? Do you have a video explaining that?

    Sherry: They are completely different things. A firewall is a system function that monitors incoming and outgoing network communication. FileVault is part of macOS and will encrypt your drive so that if the drive is removed from the machine and connected to another computer, it cannot be read.
