- The Mac Client for OneDrive Pro ( SkyDrive Pro ) seems to be 'In Development'[1] (OneDrive For Business Sync for Mac). But the OneDrive App works for OneDrive for Business too.

- OneDrive now supports 10GB files.[2]

- I am not certain but from what I know. The 20,000 limit is a suggested limit which isn't imposed. One can upload more than 20,000 files but above 20,000 files there is some sync issue with the present sync tool.
