Fix Microsoft Word Freezing When Opening Large Documents on Mac
Question details
The user needs to fix an issue where the word processor becomes unresponsive and freezes when opening documents exceeding 100 pages.

- Product
- Microsoft Word for Mac
- Device & OS
- M1 Mac running macOS Sonoma
- Scenario
- Opening and editing lengthy, large-sized documents.
- Observed behavior
- The application freezes completely, rendering the user unable to view or edit the large document.
Test whether a smaller or newly created document also freezes on your Mac. This will help you determine if the application is malfunctioning entirely or if the problem is strictly related to large files.
Roll Back to an Earlier Version of Microsoft Word
If the freezing issue started after a recent update, reverting to a previous stable version often resolves compatibility bugs on M1 Macs running macOS Sonoma.
Software updates occasionally introduce bugs that affect memory management for large files on Apple Silicon. Rolling back allows you to use a stable build while Microsoft patches the current version.
Open Microsoft Word, click on 'Word' in the top Apple menu bar, and select 'About Microsoft Word' to note your current version number.
Close Word, open your Applications folder, and drag the Microsoft Word application to the Trash to uninstall it.
Visit the official Microsoft Office for Mac Update History page in your browser. Locate a version released prior to your current one and download the installation package.
Run the downloaded installer. Once installed, open Microsoft AutoUpdate (via Help > Check for Updates in Word) and disable automatic updates to prevent the buggy version from reinstalling.

Transfer Document Content to a New File
Large documents can accumulate hidden formatting corruption over time. Transferring the text to a fresh file can eliminate these underlying errors.
Try WPS Office for Fast, Freeze-Free Document Editing on Mac
If Microsoft Word continues to struggle with lengthy files on your M1 Mac, switch to WPS Office. It is highly optimized for Apple Silicon, completely free, and handles large 100+ page documents with ease while maintaining full compatibility with your existing Word files.
- 1. Download and Install WPS Office: Visit the official WPS website and download the Mac version, which is natively optimized for fast performance on Apple Silicon.

Frequently Asked Questions
Why does Microsoft Word freeze on my M1 Mac when opening large documents?
Large documents require more memory and processing power to render text, images, and complex formatting. Recent app updates may have introduced compatibility bugs with macOS Sonoma or Apple Silicon architecture, leading to memory leaks or app unresponsiveness during the rendering process.
How do I stop Microsoft Word from automatically updating on Mac?
Open Microsoft Word, click on 'Help' in the top menu bar, and select 'Check for Updates'. When the Microsoft AutoUpdate window appears, uncheck the box labeled 'Automatically keep Microsoft Apps up to date'.
Could document corruption cause Word to freeze?
Yes. Hidden formatting errors, broken tables, or corrupted graphic elements within a large document can cause Word to enter an infinite processing loop when trying to display the pages. Copying the text to a brand-new file usually bypasses these corrupted elements.
