Solution 1Recommended

Remove Manually Copied Applications and Reinstall Office

If you transferred Office applications by manually copying them instead of using Apple Migration Assistant, the required license files are missing. You must perform a clean installation.

Manually dragging and dropping Microsoft Office applications from an old Mac to a new one does not carry over the hidden license and activation files. To restore editing functionality, you need to remove these incomplete files and install the software using the official package.

1
Delete existing Office applications

Open the Applications folder on your new Mac, select all Microsoft Office applications (such as Word, Excel, and PowerPoint), and drag them to the Trash.

2
Download the official installer

Navigate to account.microsoft.com in your web browser, sign in with the account tied to your one-time Office purchase, and go to the 'Services & subscriptions' section to download the correct installer for your version.

3
Install the software

Double-click the downloaded .pkg file and follow the on-screen prompts to properly install Microsoft Office on your new Mac.

4
Sign in to activate

Launch any newly installed Office application. When the 'What's New' or activation screen appears, click 'Get Started' or 'Sign In' and enter your Microsoft account credentials to activate the license.

Apple Migration Assistant: If you use Apple Migration Assistant for your initial setup, it typically transfers the necessary license files automatically. However, if activation still fails, following the reinstallation steps above will resolve the issue.

Frequently Asked Questions

Why does my Office for Mac say 'Read Only' after moving to a new Mac?

This happens when the Microsoft Office license files are not successfully transferred to the new Mac. Manually dragging the application files over does not carry over the DRM license, which triggers a read-only or unauthorized state.

Does Apple Migration Assistant transfer Microsoft Office licenses?

Yes, in most cases, Apple Migration Assistant will successfully transfer the necessary hidden license files along with your applications. If it fails or you chose not to migrate applications, you will need to sign in and reactivate manually.

Can I transfer a one-time purchase of Office for Mac to a new computer?

Yes, you can transfer a one-time purchase license to a new Mac. However, because the license agreement typically limits you to one active device, you may need to uninstall it from the old Mac first and then activate it on the new machine using your Microsoft account.

Where do I find the official installer for my older version of Office for Mac?

You can download the official installer by logging into your Microsoft account at account.microsoft.com, navigating to the 'Services & subscriptions' page, and clicking the download button next to your specific Office purchase.
