Frequently Asked Questions

Why does OneDrive say it isn't running when it is open on my Mac?

This misleading prompt usually occurs due to a corrupted application cache, outdated app files, or compatibility bugs specific to macOS Monterey 12. Resetting the OneDrive app can clear these erroneous state messages.

What should I do if the OneDrive update fails to install on macOS Monterey?

If you receive an error message during installation, completely uninstall the existing OneDrive app by moving it from the Applications folder to the Trash. Empty the Trash, restart your Mac, and then run the newly downloaded installer.

Can I run the latest OneDrive version on older Intel Macs?

Yes, Microsoft continues to update OneDrive for older architectures, but some newer features may require macOS 13 or later. Always check the Microsoft release notes to download the specific build recommended for macOS Monterey and Intel processors.

Will resetting the OneDrive app delete my local files?

No, resetting the OneDrive application does not delete your files. It simply disconnects the sync connection and clears local application settings. Once you sign back in, OneDrive will verify and reconnect your existing synced folders.
