Fix PowerPoint for Mac Not Opening Due to Chart.framework Error
Question details
The user is unable to launch PowerPoint on their Mac due to an invalid code signature error specifically related to the Chart.framework component.
- Product
- Microsoft PowerPoint
- Device & OS
- Mac
- Scenario
- Attempting to launch the Microsoft PowerPoint application on a macOS device.
- Observed behavior
- PowerPoint fails to open, displaying a system error indicating that a component, such as Chart.framework, has an invalid code signature or is damaged.
Make sure you have your Microsoft Office account credentials handy and ensure all background Office applications are closed before performing container resets or reinstallations.
Reset PowerPoint Container Data
Clearing the application's container folder removes corrupted preferences and cached states, forcing PowerPoint to generate fresh, working configuration files upon its next launch.
macOS isolates app data in specific 'Container' folders. When these files become corrupted or experience permission issues, they can trigger framework errors during startup. Resetting this folder is a safe first step that does not delete your actual presentation files.
Ensure PowerPoint is completely closed. If it is stuck, right-click the app icon in the Dock and select 'Force Quit'.
Open Finder. Click 'Go' in the top menu bar, select 'Go to Folder...' (or press Command+Shift+G), type '~/Library/Containers', and press Enter.
Locate the folder named 'com.microsoft.PowerPoint' (or just 'Microsoft PowerPoint' on newer macOS versions). Drag and drop this folder onto your Mac's Desktop.
Restart your Mac. Open PowerPoint again to see if the Chart.framework error is resolved. If it works, you can safely delete the folder you moved to the desktop.
Reinstall Microsoft PowerPoint
If the framework files themselves are physically damaged or have a broken digital signature, a clean reinstallation will replace them with functional, verified versions.
Run Mac Disk Utility First Aid
Checking the Mac file system can resolve deeper permissions or directory errors that might be causing macOS to falsely flag the Chart.framework signature as invalid.
Use WPS Presentation as a Hassle-Free Alternative
If Microsoft PowerPoint for Mac continues to suffer from framework crashes and invalid code signatures, consider switching to WPS Office. It provides a lightweight, exceptionally stable environment that handles presentation tasks seamlessly without heavy framework dependencies.
- 1. Download the Installer: Visit the official WPS Office website and download the free macOS version.
- 2. Install WPS Office: Open the downloaded .dmg file and drag the WPS Office icon into your Applications folder.
- 3. Open Your Presentation: Launch WPS Presentation and open your existing .pptx files to continue working immediately.
Frequently Asked Questions
What causes the Chart.framework invalid code signature error?
This error typically occurs when macOS security protocols detect that a specific internal component of PowerPoint (Chart.framework) has been corrupted, modified, or improperly updated, causing the system to block the application from launching.
Will I lose my presentations if I delete the com.microsoft.PowerPoint folder?
No. The com.microsoft.PowerPoint folder located in ~/Library/Containers only stores application preferences, temporary cache, and UI settings. Your actual presentation documents remain safe in their respective save locations.
Why didn't reinstalling PowerPoint fix the Chart.framework issue?
If a reinstall doesn't work, the corrupted framework data might be deeply cached in the macOS system, or there could be underlying disk permission errors. Running the Disk Utility's First Aid tool and thoroughly clearing the application containers usually resolves these stubborn issues.
