Product: Microsoft Word for Mac
Device & OS: macOS
Scenario: Highlighting or selecting text while editing a Word document.
Observed behavior: A gray box appears over the selected text, obstructing the view. This visual bug is often linked to older macOS versions or systems with incompatible graphics hardware.

Solution 1Recommended

Update macOS and Microsoft Word

Installing the latest software updates ensures maximum compatibility between your Mac's graphics hardware and Microsoft Word, often resolving visual glitches.

Check for macOS Updates

Click the Apple menu in the top left corner, select 'System Settings' (or 'System Preferences'), and navigate to 'General' > 'Software Update'.

Install macOS Updates

If a newer macOS version or a supplemental update is available, click 'Update Now' or 'Upgrade Now' and allow your Mac to restart.

Launch Microsoft AutoUpdate

Open Microsoft Word. In the top menu bar, click on 'Help' and select 'Check for Updates' from the dropdown menu.

Update Word

Follow the prompts in the Microsoft AutoUpdate tool to install any pending updates for Word and restart the application.

Graphics Compatibility: If your Mac is too old to receive newer macOS updates, the latest versions of Word may continue to exhibit graphics glitches. In this case, consider rolling back your Word version.

Roll Back to a Previous Version of Word

If the gray box issue began after a recent update on an older Mac, reverting to an older version of Word can bypass the graphics incompatibility.

Frequently Asked Questions

Why does a gray box appear when I select text in Word for Mac?

This is typically caused by a graphical incompatibility between the newer versions of Microsoft Word and older macOS operating systems or older Mac graphics cards. The application struggles to render the text selection highlight properly.

Will reverting to an older version of Word fix the gray box issue?

Yes, reverting to an older version can often resolve the visual glitch on older Macs. However, it may trigger activation issues, especially for Office 2021 users, requiring you to sign back in and re-verify your license.

Does this gray box affect the printed document or exported PDF?

No. The gray box is strictly a visual interface glitch within the Word application on your screen. It will not appear when you print the document or export it as a PDF file.
