This article explains how to set up and use Microsoft OneDrive for Mac on macOS 10.12 or later. It includes information about optional paid storage plans.
For OneDrive, you’ll need a Microsoft account and OneDrive for Mac. Both are free. If you don’t have a Microsoft ID yet, go to the Microsoft ID sign-in screen and click Create a Microsoft account. Once you’ve provided the requested information and created a password, you’ll have a new Microsoft ID.
