Update Word for Mac to the Latest Patched Build

Microsoft has released a specific patch (build 16.85.526.2 and later) that addresses the unresponsiveness and high energy drain caused by version 16.85.

The typing lag in version 16.85 is a recognized bug affecting Mac users, particularly on macOS Monterey and Apple Silicon (M-series) processors. Updating your Office application to the newest build restores normal CPU utilization and responsiveness.

In the AutoUpdate utility window, click the 'Check for Updates' button. Allow the system a moment to locate the latest server releases.

Install build 16.85.526.2 or later

Update Completion: After updating, monitor your Mac's Activity Monitor to ensure Word's energy impact has returned to normal levels.

Frequently Asked Questions

Why is Microsoft Word taking up so much CPU and energy on my Mac?

High CPU and energy usage in Word is typically caused by software bugs in specific application builds (like version 16.85), background syncing loops, or complex document formatting that the software fails to process efficiently. Updating to a patched version usually resolves this.

How do I check my current version of Word for Mac?

To check your version, open the Microsoft Word application. Click on 'Word' in the very top Apple menu bar, then select 'About Microsoft Word'. A dialog box will appear displaying your exact version and build number (e.g., 16.85.24052614).

Does macOS Monterey cause lag issues with Microsoft Office?

macOS Monterey is a stable operating system, but occasionally new updates to Microsoft Office introduce unexpected compatibility bugs with specific OS versions or Apple processor architectures (like the M1/M2 chips in MacBook Airs). Keeping both macOS and Office up to date is the best defense against these temporary glitches.

How can I force quit Word if the typing lag causes it to freeze completely?

If Word becomes totally unresponsive, press the keyboard shortcut Option + Command + Escape. This will open the 'Force Quit Applications' window. Select Microsoft Word from the list and click the 'Force Quit' button to terminate the frozen app.
