A Microsoft file hosting and synchronization service.
Yes—this can happen on macOS if both the standalone OneDrive app and the Mac App Store version were installed at different times. Only one version should be installed and configured on a Mac at a time. Having multiple OneDrive accounts is supported, but having two different app versions syncing the same content can cause duplicate folders and sync confusion.
A safe way to verify and clean this up:
- Check whether OneDrive is currently running.
- On Mac, the OneDrive cloud icon should appear on the top menu bar.
- If it disappears again, open Applications and start OneDrive, or use Spotlight to search for OneDrive.
- Open the OneDrive sync window from the menu bar icon.
- If a message appears saying the account is signed in to 2 versions, select Show in Finder.
- Finder should open /Library/CloudStorage.
- Inspect the OneDrive folders shown there.
- Double-click each OneDrive folder.
- If one folder shows a banner with a Delete button at the top, that folder belongs to the previous OneDrive version that is no longer installed. Select Delete for that folder.
- If there is no banner on any folder, open OneDrive preferences > Account > Unlink this Mac.
- Then start OneDrive again and complete setup. No data is lost by unlinking; it only disconnects the Mac temporarily.
- When signing in again, if OneDrive says a folder already exists, select Use this folder.
- OneDrive will re-link and sync again.
- Files may initially appear as placeholders while sync completes.
- Identify which OneDrive app version is installed, if needed.
- Open Finder > Applications > Utilities > Terminal.
- Run:
/usr/libexec/PlistBuddy -c 'Print CFBundleIdentifier' /Applications/OneDrive.app/Contents/Info.plist - Output meanings:
-
com.microsoft.OneDrive= standalone version -
com.microsoft.OneDrive-mac= Store version
-
- Identify which version is actually set up to sync.
- In Terminal, run:
xattr -l ~/OneDrive - Output meanings:
-
com.apple.file-provider-domain-id: com.microsoft.OneDrive.FileProvider/OneDrive= standalone version -
com.apple.file-provider-domain-id: com.microsoft.OneDrive-mac.FileProvider/OneDrive= Store version
-
- In Terminal, run:
- If the issue is caused by both app versions being installed, remove the previous installation properly.
- Right-click or Control-click the OneDrive app.
- Select Show package contents.
- Open Contents/resources/reset.command*.
- Then install the latest OneDrive for macOS from the preferred source and complete setup.
Important:
- Do not run both the standalone and App Store versions side by side.
- If a second folder contains files that are not yet visible in the active OneDrive folder or online, verify them before deleting anything.
- If the icon disappears and OneDrive seems not to be running, OneDrive can also be reset from Contents > Resources by running ResetOneDriveApp.command or ResetOneDriveAppStandalone.command. This is a corrective step and should be used carefully because it resets the local app state before setup is completed again.
