Fix Excel for Mac Cannot Refresh Data After macOS Ventura Upgrade
Question details
Excel for Mac fails to update linked data types and repeatedly prompts the user to sign out and sign back in following a macOS Ventura upgrade.
- Product
- Microsoft Excel for Mac
- Device & OS
- macOS Ventura
- Scenario
- Attempting to refresh data types in an Excel workbook after upgrading the Mac operating system.
- Observed behavior
- The application cannot refresh data types, triggering a persistent authentication loop that asks the user to sign out and back into their subscription account, even after clean OS installations.
Ensure you know your Microsoft account email and password, as you will need to log back in after clearing your saved credentials.
Clear Office Credentials and Update Excel
Remove corrupted authentication tokens from your Mac's Keychain and force Excel to update.
Upgrading to macOS Ventura can sometimes cause Office credentials stored in your Keychain to become corrupted. Clearing these credentials and ensuring Excel is updated often resolves the sign-in loop.
Open Excel for Mac, click on the Excel menu at the top, and sign out of your Microsoft account. Close the application completely.
Open the Keychain Access app on your Mac via Spotlight Search. Search for 'Microsoft Office' and delete any saved cached passwords or authentication session tokens.
Open Excel again, navigate to Help > Check for Updates in the menu bar, and install the latest available version to patch Ventura compatibility issues.
Sign in with your Microsoft subscription credentials and attempt to refresh your data types again.
Revert to an Earlier Build of Excel (Workaround)
If the latest update is strictly incompatible with macOS Ventura, rolling back to an older, stable build like 16.63 can bypass the bug.
Try WPS Office for Mac for a Bug-Free Experience
If Microsoft Excel continues to experience authentication loops on macOS Ventura, WPS Office is an excellent alternative. It offers native Mac support and robust spreadsheet capabilities without the frustrating subscription sign-in bugs.
- 1. Download WPS Office: Visit the official WPS Office website and download the Mac installer.
- 2. Install the Application: Open the downloaded file and follow the on-screen instructions to install WPS Office on your Mac.
- 3. Open Your Spreadsheet: Launch WPS Spreadsheets and open your existing Excel files to continue working immediately.
Frequently Asked Questions
Why does Excel keep asking me to sign in on Mac?
This usually occurs when macOS Keychain tokens for Office become corrupted or out of sync after a major system update, such as moving to macOS Ventura.
Does the Excel web app have this data refresh issue?
No. The Excel web application relies on your browser's authentication session rather than the local Mac Keychain, so it successfully bypasses this data refresh loop.
How do I stop Microsoft AutoUpdate on my Mac?
Open any Office application like Excel, click on 'Help' in the top menu bar, select 'Check for Updates', and uncheck the automatic update box to prevent it from overwriting a stable rolled-back version.
