MacReset OneDrive Tool · macOS only

MacReset OneDrive Tool — reset broken OneDrive on Mac and force a clean re-link.

MacReset OneDrive Tool is a free signed macOS .pkg that removes corrupted local OneDrive sync state — Cloud Storage mounts, File Provider data, containers, and cached account links — so OneDrive can reconnect cleanly. Your cloud files remain intact. Only the broken local sync engine is wiped.

OneDrive itself remains installed and your cloud files remain intact. This reset only removes broken local sync data on this Mac user profile.

What this OneDrive reset actually does

This reset does not uninstall OneDrive. It removes only the corrupted local sync state.

  • Unlinks the current OneDrive account from this Mac user profile
  • Deletes the local OneDrive sync database and cached cloud state
  • Removes stale Cloud Storage mount points from Finder
  • Clears stuck File Provider and background sync services
  • Forces OneDrive to behave like a first-time launch again

What it does not do

  • Does not uninstall OneDrive.app
  • Does not delete files stored in OneDrive or SharePoint cloud storage
  • Does not affect other Microsoft Office applications
  • Does not touch other user accounts on the Mac
This tool resets OneDrive’s local state only. It does not remove applications or modify the macOS operating system.

OneDrive problems this reset fixes

If any of these scenarios look familiar, this reset is designed for exactly your situation.

Stuck on “Processing changes” or “Signing in”

OneDrive runs but never completes sync or login.

Wrong or old Microsoft account

Mac keeps trying to sign into an old staff member’s tenant.

Too many OneDrive folders

Multiple personal, business and historical company folders under ~/Library/Cloud Storage/.

  • Broken File Provider placeholders

IT needs a predictable wipe

How the OneDrive reset works

Same principle as our other tools — remove the broken local data so OneDrive can rebuild correctly.

1

Quit OneDrive completely

Menu bar → Settings → Quit OneDrive, or kill the process.

2

Local sync state is wiped

The reset removes Cloud Storage mounts, File Provider state, containers, caches, and account link data.

3

Reopen OneDrive and sign in

Launch OneDrive again, sign into the correct Microsoft account, and select which folders to sync.

This reset permanently deletes OneDrive’s local sync engine and cached connection data on this Mac user profile.

Any files that only existed locally and never uploaded to OneDrive will be permanently lost.

Always confirm important files exist at onedrive.live.com or in SharePoint before running this reset.

Manual method (if you prefer doing it yourself)

These are the same steps our reset package performs safely and automatically. Manual execution is slower and easier to get wrong.

1. Quit OneDrive

From the menu bar icon, choose Quit and confirm the process is not running.

2. Remove Cloud Storage entries

In Finder go to ~/Library/Cloud Storage/ and delete folders that start with OneDrive.

3. Clear OneDrive containers

Remove OneDrive containers and group containers under ~/Library/.

Manual resets are more error-prone and often leave behind identity tokens or broken File Provider state. The automated reset exists to avoid those partial failures.
This reset follows Apple’s supported Cloud Storage and File Provider removal process. No system files outside OneDrive are modified.
