Fix OneDrive Another Version Is Signed In Error on Mac
Question details
Users need to resolve a conflict where OneDrive for Mac prevents login by incorrectly stating that another version of the app is already signed in.
- Product
- Microsoft OneDrive
- Device & OS
- macOS
- Scenario
- Setting up or using OneDrive to sync files and manage backup folders on an Apple Mac computer.
- Observed behavior
- The OneDrive application blocks the user from signing in, displaying an error message that another version is signed in. This often occurs when using the Apple App Store version, which also lacks certain folder backup functionalities.
Before making changes to the application, manually copy any local, unsynced files from your OneDrive folder to your Mac's Desktop to prevent accidental data loss during reinstallation.
Reinstall the Standalone Version of OneDrive
Removing the Apple App Store version of OneDrive and installing the standalone version directly from Microsoft resolves the sign-in conflict and restores full backup functionality.
The version of OneDrive available on the Apple App Store is subject to Apple's sandboxing restrictions, which can cause conflict errors and limit access to deeper system features like managing backup folders. Switching to the standalone Microsoft version provides a complete feature set.
Open Finder and navigate to your Applications folder. Right-click the OneDrive app, select 'Show Package Contents', go to Contents > Resources, and double-click the 'ResetOneDriveApp.command' file to clear out conflicting cached settings.
Once the script finishes, return to the Applications folder and drag the OneDrive application to the Trash. Empty the Trash to ensure the app is fully removed.
Click the Apple logo in the top-left corner of your screen and select 'Restart' to reboot your system and clear any lingering background processes.
Visit the official Microsoft OneDrive website in your browser, download the macOS standalone installer package, and run it to install the unrestricted version of the app.
Work Seamlessly on Mac with WPS Office
While resolving your Microsoft OneDrive syncing issues, consider using WPS Office as your primary productivity suite. It offers a lightweight, completely free alternative to Microsoft Office that is fully optimized for macOS.
- 1. Download for Mac: Visit the official WPS Office website and download the macOS installation package.
- 2. Install the App: Open the downloaded file and drag the WPS Office icon into your Applications folder.
- 3. Open Office Files: Launch WPS Office and directly open your existing DOCX, XLSX, and PPTX files with perfect formatting.
Frequently Asked Questions
Why does the Mac App Store version of OneDrive lack backup features?
The Apple App Store imposes strict sandboxing security rules on all its applications. This prevents the App Store version of OneDrive from accessing the system-level permissions required to manage and back up core macOS folders like Desktop or Documents.
Will I lose my files if I uninstall OneDrive from my Mac?
No, uninstalling the OneDrive application does not delete your files from the cloud. However, to ensure absolute safety, you should always back up any local files that haven't finished syncing before removing the application.
What does the ResetOneDriveApp.command script do?
The reset script is a built-in troubleshooting tool located inside the OneDrive application bundle. It resets corrupted preference files, clears login items, and removes cached data, ensuring a completely clean state for your next installation.
How do I know if I installed OneDrive from the App Store or Microsoft?
You can open the App Store on your Mac and check your purchase history. Alternatively, open OneDrive Preferences, click the 'About' tab, and check the version number. Standalone versions usually update through Microsoft AutoUpdate rather than the App Store.
