I have a Microsoft 365 Subscription on my present Lenovo laptop. I just bought a MacBook Air and want to add a subscription to it. The instructions I have read so far tell me to open Word or some other similar Microsoft program on my Mac. I don't have any. Please help.

    To use the existing Microsoft 365 subscription on the new MacBook Air, install and activate the Office apps there using the same Microsoft account as on the Lenovo.

    Follow these steps:

    1. On the MacBook Air, open a browser and go to https://www.office.com.
    2. Sign in with the same Microsoft account used for the current Microsoft 365 subscription on the Lenovo.
    3. After signing in, select Apps (or similar) and then choose Install apps. This downloads the Office installer for Mac.
    4. Run the downloaded installer and complete the installation of Word, Excel, PowerPoint, etc.
    5. Open one of the apps (for example, Word). When prompted, sign in with the same Microsoft account to activate the apps under the existing subscription.

    Microsoft 365 subscriptions allow installation on both PC and Mac, so no additional subscription purchase is required; just install and sign in on the Mac.

    To Install Microsoft 365 on your new MacBook Air, please try this:

    1. On your Mac, open Safari (or any browser)

    3. Sign in with the same Microsoft account you use on your Lenovo PC (the account that already has Microsoft 365)
    4. After signing in, click Install apps > Install Microsoft 365
    5. A file like Microsoft_Office_Installer.pkg will download
