OneDrive
Microsoft OneDrive is a cloud storage and file sync app that keeps selected files and folders synchronized with your Microsoft account.
What is OneDrive?
OneDrive is Microsoft's cloud storage and synchronization application. On Mac, people commonly use it to sync documents, desktop folders, shared work files, and Microsoft 365 content across devices. Users may encounter it as a menu bar app, a background sync process, or a login item that starts automatically to keep files up to date.
Safety overview
Status: Safe
This is a legitimate Microsoft application. It is generally safe to keep installed, but removing or disabling it can stop file syncing and may affect access to locally cached or online-only OneDrive files.
Recommendation: Keep it if you use OneDrive, Microsoft 365, or shared folders that rely on sync. If you do not use OneDrive, it is usually reasonable to disable its auto-start or remove the app after confirming no needed files depend on its local sync setup.
