OneDrive ➹

OneDrive is Microsoft’s file synchronization service, available for most platforms (except Linux).

On macOS it has a number of relevant shortcomings when compared to Dropbox, namely:

• Inability to sync with macOS extended attributes
• Inability to sync various macOS filenames (limited to the subset of valid Windows filenames)
• Severe performance issues when using tens of thousands of small files
• Occasional data loss when conflicting with Office 365 applications (which use the OneDrive API themselves, directly)
• A persistent bug that drives CPU usage to 100%, which has annoyed me for years
• Lack of feature parity (as of September 2000, Personal Vault is still not supported on macOS)

On Windows, it is notorious for using SharePoint libraries as a backing store for OneDrive for Business (like Teams).
