- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Highlighting multiple different phrases or paragraphs continuously in a document.
- Observed behavior
- The highlighter tool deactivates and reverts to the standard mouse pointer immediately after highlighting a single phrase, even after reinstalling the app and updating macOS.
Save your open documents and ensure you have administrator privileges on your Mac. Troubleshooting this issue requires accessing hidden system Library folders or creating a new user account.
Create and Test in a New macOS User Account
Creates a fresh macOS environment to bypass profile-specific corruption that causes Word's tools to malfunction.
If reinstalling Word does not resolve the bug, the issue is often tied to a corrupted macOS user profile. Testing in a new account isolates the problem.
Open System Preferences (or System Settings), navigate to Users & Groups, authenticate with your administrator password, and click the add button to create a new Administrator account.
Log out of your current profile and log into the newly created account. Open Microsoft Word, select the Text Highlight Color tool, and try highlighting multiple phrases.
If the highlighter remains active, use the new account as a workaround. Open Finder, select Go > Go to Folder, enter '/Users/', and move your documents from the old profile into the new one via the 'Shared' folder.
Clear Word Containers Cache
Removes potentially corrupted preference files that might be forcing the highlighter tool to exit prematurely.
Test Word in macOS Safe Mode
Starts macOS with minimal background programs to check if third-party software is interfering with Word's clipboard or pointer tools.

Frequently Asked Questions
How do I normally keep the highlighter tool active in Word?
When you select a color under Home > Text Highlight Color, the cursor changes to a highlighter pen icon. It should remain active for continuous use until you press the Esc key on your keyboard or manually click 'Stop Highlighting' on the ribbon.
Why didn't reinstalling Word for Mac fix the highlighter bug?
Uninstalling and reinstalling the application from the App Store generally leaves your user profile's preference files and cache intact. If those preference files are corrupted, the bug will persist across fresh installations. Clearing the Container cache or using a new user account bypasses these leftover files.
Will clearing the Word Containers cache delete my saved documents?
No, moving the Microsoft Word folder from ~/Library/Containers to your desktop only resets the application's local preferences, such as your recent file list, customized ribbon settings, and window layouts. Your actual saved document files remain completely safe and untouched.
