Dear @Fioni Murray,
I understand that you’re having trouble with your Microsoft 365 subscription on your Mac. As a forum moderator, I genuinely wish I could directly access your account or review backend systems to diagnose and resolve this for you. However, my role here is limited to providing general guidance and steps that you can apply yourself.

To assist you more effectively, could you please help clarify a few points?

  • Are you trying to install Microsoft 365 apps (such as Word, Excel, or PowerPoint) on your new Mac, or
  • Are you attempting to add the Mac as a device to your Microsoft 365 account for another purpose (for example, syncing OneDrive or managing account settings)?

Also, when you mention that you’re unable to add your Mac to your Microsoft 365 subscription:

  • Are you seeing any specific error messages, or
  • Is the device simply not being recognized after signing in?

If possible, a screenshot of the issue would be very helpful in narrowing this down. (Note: Please be sure to mask or obscure any sensitive information (such as email addresses, license keys, account IDs, or personal details) before posting screenshots on this public forum)

If the Office icons (Word, Excel, PowerPoint) aren't on your Mac Neo yet, you need to get the installer.

  1. Go to office.com and sign in with the email address associated with your subscription.
  2. On the home page > Apps, look for a button in the top-right corner that says Install apps.
  3. Select Microsoft 365 apps > Apps and devices > Install office. This will download a .pkg file to your Downloads folder.
  4. Open that file and follow the on-screen prompts to install the software.

Once the apps are installed, you need to "link" the Mac to your account.

  1. Open Word from your Applications folder or Launchpad.
  2. A "What's New" window usually appears. Click Get Started.
  3. Click Sign In and enter the email and password for your subscription.
  4. This activates the license. Your Mac Neo is now officially "added" to your subscription.

I hope this information is helpful. Please follow these steps and let me know if it works for you. If not, we can work together to resolve this. Thank you for your patience and understanding. If you have any questions or need further assistance, please feel free to share them in the comments so I can continue to support you. I'm looking forward to your reply.

    Hi, as Francesco on your Mac sign into https://account.microsoft.com/services with the Microsoft Account associated with your Microsoft 365 Subscription. You will see an install link for your subscription.

    Hi, have you tried signing into your microsoft account and download the img file needed to install Office on your Mac?

    Be sure to select the Mac install, not the PC one.

    Hope this helps,

    Francesco
