    Hello June Burlingame Smith,

    Could you share the exact wording of the sign-in prompt, or upload a screenshot with any email address or personal information hidden?

    There are two different possibilities:

    • If macOS is requesting permission to install Office, use the administrator username and password used to unlock the iMac.
    • If Office says “Sign in to activate,” use the Microsoft account email associated with the Office purchase or Microsoft 365 subscription.

    The exact prompt will confirm which credentials are required.

    Your iMac sign-in name is the macOS account name shown by your Home folder.

    1. Open Finder.
    2. In the menu bar, select Go → Home.
    3. The name of the Home folder is your Mac account/sign-in name. At the iMac login screen, macOS may also accept the full name associated with that account. ^1^

    You can also open Apple menu → System Settings → Users & Groups to see the user accounts on the iMac. ^2^

    If Microsoft 365 installation asks for a Mac login password, enter the password used to unlock the iMac—not a Microsoft password. ^3^

    If Office instead says “Sign in to activate,” use the email address and password associated with your Microsoft 365 subscription.
