How to Fix Line Numbering Options Not Opening in Word for Mac

Product: Microsoft Word
Device & OS: macOS
Scenario: Attempting to customize page layout and line numbers after a recent Office or macOS software update.
Observed behavior: Clicking on Line Numbering Options under the Layout tab does nothing, preventing the user from adjusting line numbering settings.

Before you start

Ensure you have saved all open documents and completely closed out of all Microsoft Office applications, as these troubleshooting steps require modifying preference files and restarting your Mac.

Solution 1Recommended

Remove the Word Container Folder

Clearing corrupted application preference files stored in the Mac Library often restores missing or unresponsive dialog features.

Major macOS or Office updates can sometimes corrupt local preference files. Removing the specific Microsoft Word container forces the app to generate a fresh, glitch-free configuration upon its next launch.

Force Quit Word

Ensure Microsoft Word is completely closed. If it is unresponsive, press Option + Command + Esc, select Microsoft Word, and click Force Quit.

Access the Library Folder

Open Finder. Click 'Go' in the top Apple menu bar, hold down the Option key on your keyboard, and click on 'Library' when it appears in the dropdown.

Locate the Word Container

Open the 'Containers' folder. Look for a folder named 'com.microsoft.Word' (on newer versions of macOS, it might simply be labeled 'Microsoft Word').

Delete and Relaunch

Drag this folder to the Trash. Restart Microsoft Word, navigate to the Layout tab, and test the Line Numbering Options dialog.

Data Safety: Deleting this container folder will not delete your saved Word documents. It only resets application preferences and caches.

Solution 2

Restart Your Mac in Safe Mode

Starting your Mac in Safe Mode clears the system cache and prevents interfering background programs from running.

Frequently Asked Questions

Why do layout options in Word for Mac stop working after an update?

System or Office updates can occasionally cause permission conflicts or corrupt cached preference files located in the macOS Library folder. When Word attempts to access these corrupted files, specific features like the Line Numbering dialog may fail to open.

How do I find my current Microsoft Word for Mac version?

To check your version, open Microsoft Word, click on the 'Word' menu in the top Apple menu bar, and select 'About Microsoft Word'. This window will display your exact version number (e.g., 16.78) and your license type.

Will removing the com.microsoft.Word folder delete my custom templates?

Removing the container folder resets application preferences but generally keeps your documents safe. However, custom templates stored within the container might be affected. It is recommended to drag the folder to the Desktop first as a backup rather than emptying the Trash immediately.
