Downgrade Microsoft Word to Version 16.84 or Earlier
Reverting to an older, stable version of Microsoft Word can bypass the performance bugs introduced in recent updates.
Multiple users have reported severe performance drops, including typing lag and slow document loading, after recent Office for Mac updates. Since basic troubleshooting like restarting the Mac does not resolve this update-specific bug, the most effective solution is to temporarily downgrade to version 16.84 or an earlier stable release until Microsoft releases an official patch.
Open the Applications folder on your Mac, locate Microsoft Word, and drag it to the Trash. Empty the Trash to completely remove the application.
Navigate to the official Microsoft Office for Mac Update History page in your web browser. Scroll down to find version 16.84 (or an earlier stable build) and download the standalone Microsoft Word installer package.
Double-click the downloaded .pkg file and follow the on-screen instructions to install the older version of Microsoft Word onto your Mac.
Open Microsoft Word, click on 'Help' in the top menu bar, and select 'Check for Updates'. Uncheck the option to automatically keep Microsoft Apps up to date so your Mac does not immediately reinstall the problematic version.
