How to Fix Excel Not Opening on Mac After macOS Monterey Update
Question details
Microsoft Excel fails to launch on Mac following a system update, displaying a missing or invalid Chart framework library error.
- Product
- Microsoft Excel
- Device & OS
- macOS Monterey 12.5
- Scenario
- Launching Microsoft Excel after a recent macOS system update.
- Observed behavior
- Excel crashes on startup and reports that the Chart framework library is missing or has an invalid code signature.
Ensure your Mac is connected to a stable internet network for downloading updates, and verify which version of Microsoft Office you are currently running.
Update Microsoft Office to the Latest Version
Installing the latest Office updates often resolves compatibility issues and framework errors introduced by newer macOS versions.
Older versions of Microsoft Office may lack the proper code signatures required by macOS Monterey. Updating the application ensures full compatibility and security compliance.
Download and run the Microsoft AutoUpdate tool if your applications are unresponsive, or open another working Office app like Word and select Help > Check for Updates.
Follow the on-screen prompts to check for updates and click 'Update' to install the latest available version of Microsoft Excel.
Restart your Mac to apply system changes, then attempt to launch Excel again.
Clear the Microsoft Excel Container Folder
Resetting the application container can fix startup issues caused by corrupted preferences or cache files.
Completely Uninstall and Reinstall Office
If updating and clearing the cache fail, a clean installation ensures all framework libraries are intact and correctly signed.
Use WPS Office as a Seamless Alternative on Mac
If Microsoft Excel continues to crash or you are using an older, unsupported version of Office on macOS Monterey, consider switching to WPS Office. It is a highly compatible, free alternative that works beautifully on modern Macs.
- 1. Download WPS Office: Visit the official WPS website and download the Mac installer.
- 2. Install the Application: Open the downloaded package and follow the quick installation prompts to add it to your Applications folder.
- 3. Open Your Spreadsheets: Launch WPS Office, click 'Open', and select your existing Excel files to continue working seamlessly.
Frequently Asked Questions
Why does Excel say a framework library is missing after a macOS update?
Major macOS updates often introduce stricter security protocols or deprecate older system files. If Excel's code signatures do not meet the new OS requirements, or if the app files become corrupted during the OS transition, it triggers a framework missing or invalid signature error.
Will moving the Excel container folder delete my spreadsheets?
No. The ~/Library/Containers/ folder only stores application preferences, templates, and temporary cache files. Your actual spreadsheets saved in your Documents or other personal folders remain completely safe.
What should I do if my version of Office is no longer supported on macOS Monterey?
If you are running an older, unsupported version like Office 2011 (14.x) or earlier, it will not run on modern macOS versions. You can either purchase a Microsoft 365 subscription, or switch to a free alternative like WPS Office to continue editing your files without spending money.
Can I downgrade my macOS to make my old Excel version work again?
While it is technically possible to downgrade macOS using a Time Machine backup or a bootable installer, it is generally not recommended due to security risks and the complexity of the process. Updating your Office software or using a modern alternative is much safer.
