- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Working on documents in Microsoft Word on a Mac environment
- Observed behavior
- The application unexpectedly crashes and generates an error report logging an EXC_BAD_INSTRUCTION error involving AppKit and an Objective-C exception.
Ensure you have saved all your ongoing work and completely closed all Microsoft Office applications before attempting to clear application cache folders or perform a reinstallation.
Clear the Microsoft Word Cache Container
Moving the corrupted Word container folder to the desktop forces the application to create a fresh cache, which often resolves unexpected AppKit and Objective-C exception crashes.
macOS stores application cache and preference files in an isolated Container folder. Over time, these files can become corrupted and cause sudden crashes, such as the EXC_BAD_INSTRUCTION error.
Ensure that Microsoft Word, Excel, and PowerPoint are completely closed on your Mac.
In Finder, press Command + Shift + G on your keyboard, type ~/Library/Containers in the search box, and press Enter.
Locate the folder named com.microsoft.Word (or simply Microsoft Word on newer macOS versions) and drag it to your Mac's desktop.
Open Word again to test if the crash is resolved. If the application runs smoothly, you can safely move the old folder from your desktop to the Trash.
Update or Reinstall Microsoft Office
If clearing the cache does not work, the application files may be severely corrupted. Updating to the latest stable build or performing a clean installation can fix persistent errors.

Frequently Asked Questions
What does the EXC_BAD_INSTRUCTION error mean in Word for Mac?
This error typically indicates that the application attempted to execute an illegal or undefined processor instruction. In Microsoft Word for Mac, it is most often triggered by corrupted cache files, incompatible add-ins, or instability in a beta release of the software.
Will I lose my documents if I delete the com.microsoft.Word folder?
No, removing or relocating the com.microsoft.Word container folder will not delete your saved documents. It only clears user preferences and temporary cache files. However, it is safer to move it to the desktop first to ensure the application recreates the cache properly.
Why is Microsoft Word crashing only on the beta build?
Beta builds are pre-release versions intended solely for testing new features and often contain unresolved bugs. If you experience frequent AppKit or Objective-C crashes on a beta channel, it is highly recommended to install the latest patch or revert to the stable release channel.
