Reset the OneDrive app on Mac OS X

From time to time we have customers telling us that their OneDrive app on their Mac is not syncing correctly with their cloud based storage. In other words, the files on their Mac that they save to their local OneDrive folder are not syncing to their actual OneDrive or their other devices.This problem requires that users reset their OneDrive app on their Mac. A quick fix may be to just reinstall the OneDrive app by dragging the app in the Applications folder (Finder / Applications) to the trash and then reinstalling the app via the App Store. If this does not work we advise the following steps:

  • It is always a good idea to backup your entire Mac using the built-in TimeMachine utility when there is a possibility of data loss. This step is optional but recommended.
  • Quit OneDrive by right clicking on the OneDrive icon in the Menu Bar (top RHS of screen).
  • Open Finder / Applications and right click on the OneDrive app. Select ‘Siew package contents’
  • In Contents / Resources, double-click on ResetOneDriveApp.command – a script will run.
  • Start OneDrive and re-enter your login credentials.
  • The OneDrive app will ask for a local folder location – choose the same folder as before and merge the changes with the cloud based version of your OneDrive folder.

That’s it. The folder will sync the local changes to the cloud and all your devices will be in sync again.
