Software updates occasionally introduce bugs that affect performance. Uninstalling the problematic version and downloading the previous stable release will restore smooth functionality.

Install the older version

Run the downloaded installer package and follow the on-screen prompts to reinstall Microsoft Word on your Mac.

4
Disable automatic updates

Launch Word, go to 'Help' in the top menu bar, select 'Check for Updates', and uncheck 'Automatically keep Microsoft Apps up to date' to prevent the buggy version from reinstalling.

Frequently Asked Questions

Why did Microsoft Word suddenly start lagging on my Mac?

Sudden lagging and scrolling delays are often caused by bugs introduced in recent software updates, such as Office for Mac version 16.85. Reverting to the previous update can quickly resolve the performance drop until an official patch is released.

How can I stop Microsoft Word from automatically updating to the buggy version?

Open any Office application on your Mac, click on 'Help' in the top menu bar, select 'Check for Updates', and turn off the toggle or uncheck the box for 'Automatically keep Microsoft Apps up to date'.

Can a corrupted Word document be completely restored on Mac?

It depends on the severity of the corruption. You can often salvage the raw text using the 'Recover Text from Any File' option in the Open dialog, or locate an earlier auto-saved version in the AutoRecovery folder. However, complex formatting and images might not be recoverable.
