Reset the OneDrive App and Clear Cache
Resetting the OneDrive app's core files and clearing corrupted cache folders is the most effective way to resolve startup errors on Mac.
This solution clears out corrupted local files and temporary credentials that prevent the app from launching properly.
Click the OneDrive icon in your Mac's menu bar, navigate to Help & Settings > Preferences > Account, and select 'Unlink This Mac'.
Open the 'Keychain Access' app from your Mac's Utilities folder. Use the search bar to find 'OneDrive Cached Credential' and delete the entry.
Open Finder, click 'Go' in the top menu bar, and select 'Go to Folder'. Enter '~/Library/Containers' and move any folders related to 'com.microsoft.OneDrive' to your Desktop or Trash.
Open the Applications folder, right-click the OneDrive app, and select 'Show Package Contents'. Navigate to Contents > Resources and double-click the 'ResetOneDriveApp.command' or 'ResetOneDriveAppStandalone.command' file to run it.
Restart your Mac, then launch OneDrive from the Applications folder and sign back in to set up your sync folder.

Frequently Asked Questions
Will I lose my files if I reset the OneDrive app on my Mac?
No, resetting the OneDrive application only clears the app's local configurations, cached credentials, and temporary files. Your synced files remain securely stored in the cloud and will become accessible locally again once you sign back into the app.
Why does OneDrive keep displaying the 'application files problem' error?
This error typically occurs when the local cache becomes corrupted, there is a conflict in the Mac Keychain credentials, or a recent macOS update disrupts the application's file permissions.
Where can I find the ResetOneDriveApp.command file?
To find the reset command, open your Applications folder in Finder, right-click the OneDrive app, and select 'Show Package Contents'. From there, navigate to the 'Contents' folder, open 'Resources', and you will locate the 'ResetOneDriveApp.command' file.
Can I access my synced files while troubleshooting the desktop app?
Yes, your files are always accessible via the web. You can view, download, and manage your documents by logging into onedrive.com through Safari or any other web browser while you troubleshoot the Mac desktop application.
