Frequently Asked Questions

Why does Word for Mac use 100% CPU when opening OneDrive files?

This is a known synchronization and rendering issue acknowledged by Microsoft. When Word attempts to open a file directly from a live-syncing OneDrive directory on recent macOS versions, it can get stuck in a rendering loop, leading to maximum CPU usage and a spinning wait cursor.

How do I force quit Word for Mac if it is completely frozen?

Press the Option, Command, and Esc (Escape) keys simultaneously to open the 'Force Quit Applications' window. Select 'Microsoft Word' from the list and click the 'Force Quit' button to close the frozen application.

Does disabling OneDrive 'Files On-Demand' fix the spinning cursor issue?

In some cases, yes. By opening OneDrive preferences and ensuring your files are marked to 'Always keep on this device', you force OneDrive to download the full file locally, which can sometimes bypass the live-sync rendering delay in Word.
