Solution 1Recommended

Restart Mac and Verify Software Versions

A system restart combined with verifying software versions often resolves temporary input glitches in Microsoft Word for Mac.

Often, background processes or a temporary glitch in Microsoft 365 can cause the mouse input to stop functioning specifically within Word. Restarting the system clears these glitches. Additionally, because bug fixes vary by release, ensuring you are on a supported version is critical.

1
Save and Close Word

Save any open documents using keyboard shortcuts (Command + S) and completely quit Microsoft Word by pressing Command + Q.

2
Restart the Mac

Click the Apple menu in the top-left corner of your screen and select 'Restart'.

3
Test Text Selection

Once the Mac reboots, open Word and test if you can select text using the left mouse button.

4
Check Version Information

If the problem remains, click 'Word' in the top menu bar, select 'About Microsoft Word', and note your version number. Check for available updates via the Help > Check for Updates menu.

Microsoft 365 Versions: Make sure you provide the exact macOS and Microsoft 365 version numbers when seeking further support, as available features and fixes vary significantly by release.

Frequently Asked Questions

Why can I not highlight text in Word for Mac but can everywhere else?

This usually indicates a software-specific glitch within Microsoft Word or a conflict with a background application. Restarting the Mac or updating Word to the latest version often restores normal mouse functionality.

Will updating my macOS fix the text selection issue in Word?

It might. Updating both your macOS and your Microsoft 365 suite ensures you have the latest compatibility patches, as bug fixes and supported features vary by the exact release version.

Are there keyboard shortcuts I can use if the mouse won't select text?

Yes. Place your cursor at the beginning of the text, hold the 'Shift' key, and use the arrow keys to highlight the text. You can then use 'Command + C' to copy and 'Command + V' to paste.
