How to Fix Gray or Black Box Over Selected Text in Word for Mac
Question details
The user needs to resolve a graphical issue where a gray or black box obscures selected text and parts of the Word interface on macOS.

- Product
- Microsoft Word for Mac
- Device & OS
- macOS Monterey or later
- Scenario
- Highlighting text or navigating through documents in Microsoft Word.
- Observed behavior
- A solid gray or black box appears over the selected text or UI elements, making it impossible to read the highlighted content or properly view the interface.
Save all open documents and ensure your Mac is connected to a stable internet connection, as you may need to download system or application updates.
Update macOS and Microsoft Word
Graphical glitches in Word are often caused by rendering conflicts between older software versions and the operating system. Updating both resolves most display issues.
This display error is commonly reported on macOS Monterey and older Mac hardware. Updating to the latest macOS version supported by your device (such as macOS Sequoia) and installing the latest Microsoft Word build ensures optimal compatibility and includes the latest bug fixes.
Click the Apple menu in the top-left corner of your screen and select 'System Settings' (or 'System Preferences'). Go to 'General' > 'Software Update' and install any available macOS updates.
Open Microsoft Word on your Mac. Click 'Help' in the top menu bar, then select 'Check for Updates'. Follow the prompts in the Microsoft AutoUpdate tool to install the newest version of Word.
Once all updates are completely installed, click the Apple menu and select 'Restart' to apply the changes and refresh the system's display drivers.

Temporarily Disable Word Add-ins
Third-party add-ins can sometimes interfere with Word's interface rendering. Disabling them helps isolate the cause of the black box issue.
Try WPS Office for a Glitch-Free Mac Experience
If Microsoft Word continues to display gray or black boxes due to macOS compatibility issues or aging Mac hardware, consider switching to WPS Office. It provides a lightweight, highly compatible, and seamless word processing experience without graphical glitches.
- 1. Download and Install: Visit the official WPS Office website and download the macOS version. Follow the standard installation prompts.
- 2. Open Your Documents: Launch WPS Office and open your existing .docx files directly. Your formatting remains intact, and you can edit without encountering the black box selection error.

Frequently Asked Questions
Why does a black box only appear when I select text in Word?
This is typically a graphics rendering glitch caused by a mismatch or bug between your specific version of Microsoft Word and the macOS display drivers, notably seen on macOS Monterey or older Mac hardware.
Will upgrading my Mac's operating system fix the Word display issue?
Yes. Upgrading to a newer version of macOS (such as Ventura, Sonoma, or Sequoia) alongside updating Microsoft Word has proven to resolve this black box text selection error for many users.
Does this graphical issue permanently damage my Word document?
No. The gray or black box is purely a visual rendering error on the interface. It does not affect the actual text, formatting, or data saved within your document.
