Locate and Uninstall the Extra OneDrive Application on Mac

Find the hidden or duplicated OneDrive application in your Mac's Applications folder and safely move it to the Trash.

On macOS, the system might have downloaded a standalone version of OneDrive while another version was installed via the Mac App Store or a Microsoft Office bundle. Removing one of the applications resolves the conflict.

1
Open the Applications Folder

Open Finder on your Mac. In the top menu bar, click on 'Go' and select 'Applications' from the dropdown list.

2
Search for Duplicate Applications

In the Applications folder search bar, type 'OneDrive'. Look closely at the results to see if there are two icons or versions of the OneDrive app.

3
Move the Extra Copy to Trash

Right-click (or Control-click) on one of the duplicate OneDrive applications—preferably the older one if you can see the version details—and select 'Move to Trash'.

4
Empty Trash and Restart

Right-click the Trash icon on your Dock, select 'Empty Trash', and then restart your Mac to clear the conflict.

Frequently Asked Questions

Will uninstalling the duplicate OneDrive app delete my files?

No, uninstalling the OneDrive application only removes the software program used to sync your files. Your local files in the OneDrive folder and the files stored safely in the cloud will not be deleted.

Why do I have two versions of OneDrive installed?

This usually happens if you manually installed a standalone version of OneDrive while also having the version bundled automatically with macOS, Windows 10/11, or a Microsoft Office package installed on the same device.

How do I know which duplicate OneDrive application to delete?

Check the version numbers or installation dates if your operating system displays them. It is generally best to keep the most recently updated version and uninstall the older one. If you are unsure, you can uninstall both copies and download a fresh, single installation from the official Microsoft website.
