- Product
- Microsoft Word for Mac
- Device & OS
- macOS
- Scenario
- Attempting to arrange document windows side-by-side using the native macOS multitasking Split View feature.
- Observed behavior
- Microsoft Word displays a 'Not Available in This Split View' message or refuses to tile to the left/right of the screen, typically after a recent macOS or Office update.
Ensure that your Word window is not already in full-screen mode, and verify that your current version of macOS supports the Split View multitasking feature.
Test Application Compatibility and Check for Updates
Isolating the issue helps confirm if the bug is exclusive to Word. Updating your software can often patch known split-screen compatibility bugs.
Compatibility issues between macOS window management and Microsoft Office often occur right after a system or software update. Verifying the scope of the problem is the best first step.
Open Excel, PowerPoint, or a web browser like Safari. Hover over the green full-screen button in the top-left corner of the window to see if Split View works for these apps.
Open Microsoft Word. On the top menu bar, click 'Help', and select 'Check for Updates'. Download and install any pending updates for your Office applications.
Click the Apple menu in the top-left corner, go to 'System Settings' (or 'System Preferences'), select 'General', and click 'Software Update' to ensure your Mac is fully up to date.

Completely Uninstall and Reinstall Office for Mac
If updating does not resolve the Split View error, corrupt application configuration files may be the cause. A clean reinstallation of Office for Mac is required.
Use WPS Office for Seamless Split View Multitasking on Mac
If Microsoft Word continues to struggle with Mac's native Split View, consider switching to WPS Office. It provides a lightweight, highly compatible alternative that perfectly supports macOS multitasking features, allowing you to work on multiple documents side-by-side without hassle.
- 1. Download WPS Office: Visit the official WPS website and download the Mac version of WPS Office.
- 2. Install and Open: Run the installer package and move WPS Office to your Applications folder, then launch the app.
- 3. Enjoy Seamless Split View: Open your Word documents in WPS Office, hover over the green window button, and select a tiling option to effortlessly use Split View.
