How to Fix Gray Selection Box Over Text in Word for Mac
Question details
Users experience a disruptive graphical glitch where a large gray box covers selected text in Microsoft Word for Mac.
- Product
- Microsoft Word for Mac
- Device & OS
- macOS Monterey
- Scenario
- Highlighting or selecting text after a document has been open for an extended period, particularly following a recent Word update.
- Observed behavior
- Instead of standard translucent text highlighting, a solid, large gray box appears over the selected text, completely obscuring the characters.
Before troubleshooting, save all your open documents and close any background applications to prevent data loss during system restarts or software downgrades.
Install an Earlier Version of Word for Mac
Downgrading to a stable, older version of Word resolves the Metal graphics rendering bug introduced in newer updates.
This is a known issue in Word for Mac versions after 16.49 when Metal graphics acceleration is unavailable or unsupported on the specific Mac hardware. Reverting to an earlier build forces Word to use the older, stable selection-highlighting method.
Open the Applications folder on your Mac, locate Microsoft Word, and drag it to the Trash.
Navigate to the official Microsoft 'Update history for Office for Mac' webpage. Find version 16.49 (or earlier) and download the installation package for Word.
Run the downloaded installer. Once installed, open Word, go to Help > Check for Updates in the top menu, and turn off automatic updates to prevent the glitchy version from reinstalling.
Start Mac in Safe Mode to Test for Conflicts
Booting into Safe Mode helps determine if background startup software or display drivers are interfering with Word's graphics rendering.
Report the Graphics Rendering Issue to Microsoft
Submitting a direct bug report ensures Microsoft is aware of how many users are affected by the lack of Metal graphics acceleration fallback.
Switch to WPS Office for a Glitch-Free Mac Experience
If Microsoft Word's graphics rendering issues are disrupting your workflow on macOS, WPS Office offers a highly compatible, lightweight, and completely free alternative. Enjoy a familiar interface without the frustrating gray selection boxes.
- 1. Download WPS Office: Visit the official WPS website and download the free macOS version of WPS Office.
- 2. Open Your Document: Launch WPS Writer, click 'Open', and select your existing Word documents to edit them natively.
- 3. Edit Flawlessly: Highlight, format, and edit your text smoothly without encountering rendering leaks or gray boxes.
Frequently Asked Questions
Why does the gray selection box only appear after the document has been open for a while?
This happens due to a graphics-rendering leak in newer versions of Word for Mac. As the application remains open, rendering issues compound on Macs lacking full Metal graphics acceleration, eventually causing the highlight color to display as a solid gray block.
Will upgrading my macOS fix the Word highlighting issue?
Not necessarily. While keeping your macOS updated is generally good practice, this specific issue is tied to Word's internal rendering engine (post version 16.49) and how it handles older Mac graphics hardware. Downgrading Word is typically more effective.
Does this gray box bug affect my printed documents or PDFs?
No, the gray selection box is purely a user interface display glitch on your screen. If you print the document or export it as a PDF, the text will display normally without any gray boxes covering it.
