One Drive Mac Container

What is One Drive Mac Container?

This folder is the app container for Microsoft OneDrive on macOS. It stores sandboxed local data that the Mac App Store version of OneDrive uses for app state, account-related information, and files needed to support syncing behavior on your Mac. Users most often encounter it when reviewing storage use, troubleshooting sync problems, or cleaning up data after uninstalling OneDrive. Because it belongs to a cloud sync app, contents in this container may affect sign-in state, local settings, and how OneDrive reconnects to synced locations. Removing it while OneDrive is installed can reset parts of the app or interrupt sync until the app is set up again.

Safety overview

Status: Mostly safe

This container is consistent with Microsoft OneDrive on macOS, especially the Mac App Store version that uses an app sandbox container. The folder can hold local app data tied to sign-in and syncing, so deleting it may sign you out, remove local app state, or require OneDrive to rebuild its setup. If you still use OneDrive, leave it in place. If you no longer use OneDrive, make sure the app is fully quit and no files are actively syncing before removing leftover container data.

Recommendation: Keep this folder if you actively use OneDrive, since it supports the app's local setup and sync behavior. Remove it only after uninstalling OneDrive or if you are intentionally resetting the app and understand that you may need to sign in again and let sync settings rebuild. If disk space is the goal, check the size of your synced OneDrive folder separately, because deleting this container does not remove all locally stored cloud files.
