Microsoft OneDrive is previously known as Microsoft SkyDrive.
Microsoft OneDrive (formerly Microsoft SkyDrive) is the easiest way to access your OneDrive from your Mac. When you install Microsoft OneDrive, a OneDrive folder is created on your computer. Everything you put in this folder is automatically kept in sync between your computers and OneDrive.com, so you can get to your latest files from virtually anywhere. Whenever you add, change, or delete files in one location, all the other locations will be updated.
If you have previously installed the SkyDrive App, please remove the app from your applications folder.
