OneDrive
Microsoft OneDrive is a cloud storage and file sync app for Mac that keeps files available across devices and in Finder.
What is OneDrive?
Microsoft OneDrive for Mac is a cloud storage and file synchronization app that helps you keep files backed up, organized, and available across devices. It places a OneDrive folder in Finder and syncs changes between your Mac and your Microsoft account, so files you add, edit, or delete stay consistent online and on other signed-in devices. The app supports Files On-Demand, which lets you browse your full library without storing every file locally, and it can keep selected files or folders available offline when you need them. OneDrive is commonly used for personal storage, work or school documents, and sharing files with other people. It also integrates with Finder so you can see sync status and manage what stays on your Mac.

Safety overview
Status: Mostly safe
OneDrive is a legitimate Microsoft file sync app. Its background syncing, Finder integration, and access to files in your OneDrive folder are consistent with its purpose. Because it handles cloud storage, review which account is signed in and what folders are being synced, especially on a shared or work-managed Mac. If you do not want continuous cloud sync or file availability through Microsoft services, sign out or unlink the Mac before removing it.
Recommendation: Keep OneDrive if you use Microsoft cloud storage for personal, school, or work files. If you no longer use it, unlink your account first so syncing stops cleanly, then remove the app to free space and reduce background activity.
