Question details

The user is unable to edit multiple Word documents on a Mac because the software displays a "selection is locked" message, which generally points to an expired license or an unactivated Office installation.

How to Fix "Selection is Locked" Error in Word for Mac

Product: Microsoft Word
Device & OS: macOS
Scenario: Attempting to type, edit, or format text in any existing or new Microsoft Word document on a Mac.
Observed behavior: Microsoft Word blocks all edits and displays the message "You can't make this change because this selection is locked" at the bottom of the screen.

Before you start

Ensure you have the login credentials for the Microsoft account associated with your Microsoft 365 subscription or Office for Mac purchase, as you will need them to verify your license.

Solution 1Recommended

Verify and Activate Your Office License

The most common reason for a locked selection in Word for Mac is that the software is not activated or the subscription has expired.

While Windows users typically check activation via File > Account, the process on macOS is slightly different. You must ensure that the correct Microsoft account is actively signed in and that your software recognizes your valid license.

Open Word's About page

Launch Microsoft Word on your Mac. In the top Apple menu bar, click on 'Word' and select 'About Microsoft Word' from the dropdown menu.

Check the license status

In the dialog box that appears, look for the 'License' field. If it says 'Not Activated' or shows an unrecognized license type, your software is operating in a read-only mode.

Activate the software

Close the 'About' window. Look for a 'What's New' or 'Activate' button at the bottom of the document gallery, or go to the 'Word' menu and click 'Activate Office'. Sign in with your licensed Microsoft account.

Activation Complete: Once activated, close all Word documents and restart the application. The locked selection restriction will be lifted.

Solution 2

Sign Out and Sign Back In to Microsoft Word

If you have a valid license but are still experiencing the error, your session token may have expired. Refreshing your login can resolve this.

Solution 3

Remove Office License Files and Re-activate

If Word still fails to recognize your active subscription, clearing old or corrupted license files from your Mac can force a clean activation.

Frequently Asked Questions

Why does Word say my selection is locked even when I have a subscription?

This happens if your Microsoft 365 subscription has recently expired, payment failed, or the application lost connection to Microsoft's licensing servers. Signing out and signing back in usually refreshes your subscription status.

Can I unlock a Word document on Mac without an active Office subscription?

Without an active subscription or purchased license, Microsoft Word for Mac enters a reduced functionality mode where you can only view or print documents. To edit them without buying a subscription, you can use a free alternative like WPS Office.

Does the locked selection message mean my file is corrupted?

No. The 'selection is locked' message is typically an application-level restriction related to licensing, not a problem with the file itself. Your document data is safe and intact.

How do I check my Office activation status on a Mac?

Open Microsoft Word, click on 'Word' in the top Apple menu bar, and select 'About Microsoft Word'. Look at the 'License' field in the pop-up window to see your current activation status.
