The user needs to resolve synchronization failures and duplicate installation errors when trying to run Microsoft OneDrive on a Mac.

How to Fix OneDrive Sync Issues and Remove Duplicate Data on Mac

Product: Microsoft OneDrive
Device & OS: macOS
Scenario: Reinstalling OneDrive on a Mac and attempting to synchronize cloud files.
Observed behavior: Files fail to appear, and OneDrive displays an error stating that another version is installed due to leftover folders and old Finder connections.

Before you start

Ensure you have a backup of any recently created local files that haven't synced yet, and fully quit the OneDrive application from your Mac Menu bar before proceeding.

Solution 1Recommended

Clear Leftover OneDrive Folders in Finder

Deleting old configuration files and duplicate OneDrive folders can resolve the conflict causing sync failure.

When OneDrive is uninstalled or updated improperly, leftover folders in your Mac's directory can confuse the new installation. Removing these folders forces OneDrive to create a fresh, clean connection.

Force Quit OneDrive

Click the OneDrive icon in the top menu bar, select the Settings gear icon, and click 'Quit OneDrive'. Alternatively, force quit it via the Activity Monitor.

Locate Old Folders

Open Finder, navigate to your user Home directory, and look for any existing 'OneDrive' folders.

Remove Duplicate Connections

Check the 'Locations' section in the Finder sidebar for any lingering OneDrive connections. Drag the old OneDrive folders and connections to the Trash.

Restart and Sign In

Restart your Mac, launch the OneDrive application again, and sign in with your credentials to initiate a fresh synchronization.

Synchronization Restored: Once the old directories are cleared, OneDrive will securely rebuild its database and pull down your files from the cloud.

If OneDrive still reports that another version is installed, running the official license removal tool can clear hidden duplicate installation data.

Frequently Asked Questions

Why does OneDrive say another version is installed on my Mac?

This happens when leftover configuration files or a lingering OneDrive shortcut in Finder's 'Locations' sidebar trick the system into thinking the app is still active or already installed.

Will I lose my files if I delete the OneDrive folder on Mac?

Deleting the local OneDrive folder will only remove the local copies. Your files stored safely in the Microsoft cloud will remain intact and will download again once synchronization is restored. Always ensure unsynced files are backed up locally first.

Where can I find the Microsoft license removal tool for Mac?

You can download it directly from Microsoft using their official link (https://go.microsoft.com/fwlink/?linkid=849815). Running this tool clears out old Office and OneDrive licenses that cause duplicate installation errors.
