How to Fix Microsoft Word for Mac Slowing Down and Crashing
Question details
The user is experiencing significant performance degradation, freezing, and application crashes when using Microsoft Word on a Mac for prolonged periods.

- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Editing and working on documents in Microsoft Word for several hours consecutively.
- Observed behavior
- The application progressively slows down over time, freezes, and eventually crashes completely, interrupting the workflow.
Ensure all your unsaved work is backed up and force quit Microsoft Word before attempting to modify system files or templates. It is also helpful to check if this issue occurs with all documents or just a specific, heavily formatted file.
Reset the Word Normal Template
A corrupted Normal template can cause memory leaks and performance issues over time. Resetting it allows Word to generate a fresh configuration, which often resolves persistent crashing.
The Normal.dotm template stores default settings, macros, and styles. When this file becomes bloated or corrupted, it severely impacts Word's performance during extended sessions on macOS.
Ensure Microsoft Word and all other Office applications are completely closed. If the app is frozen, use 'Option + Command + Esc' to Force Quit.
Open Finder, click on 'Go' in the top Apple menu bar, select 'Go to Folder...', and type '~/Library/Application Support/Microsoft/Office/User Templates' then press Enter.
Locate the file named 'Normal.dotm' (or just 'Normal'). Drag and drop this file onto your desktop to remove it from the folder without permanently deleting it yet.
Reopen Microsoft Word. The application will automatically generate a fresh, uncorrupted Normal template upon launch. Test the app by working on a document to see if the slow-down issue persists.

Install an Earlier Stable Version of Word
If the current update contains a known memory leak or bug, reverting to a previous stable build like version 16.84 can instantly restore performance.
Switch to WPS Office for a Faster, Crash-Free Experience on Mac
If Microsoft Word continues to freeze or crash on your MacBook, consider switching to WPS Office. It is a highly optimized, lightweight productivity suite that handles large documents smoothly without draining your system's resources.
- 1. Download WPS Office: Visit the official WPS website and download the Mac version of WPS Office.
- 2. Install the Application: Open the downloaded package and drag the WPS Office icon to your Applications folder.
- 3. Open Your Documents: Launch WPS Writer and open your existing .docx files directly. Enjoy smooth editing without memory leaks or unexpected crashes.

Frequently Asked Questions
Why does Word for Mac get slower the longer I use it?
This is typically caused by a memory leak in the software, where the application fails to release RAM back to the macOS system. Background features like grammar checking, auto-recovery, and processing heavily formatted graphics can exacerbate this issue over an extended period.
Will deleting or moving the Normal template delete my saved documents?
No, moving the Normal.dotm template only resets default formatting settings, custom macros, and styles. Your saved documents, text, and files will remain completely intact and untouched.
How do I know if a specific document is causing the slow-down?
Try creating a brand new, blank document and typing in it for a few hours. If the application does not slow down or crash, the issue is likely tied to file corruption, large embedded images, or complex formatting within your original document.
