Go further with iCloud Drive
You might be surprised by what you can do with iCloud Drive...
You can set up iCloud Drive on a Mac, mobile device or Windows PC. On a Mac, open System Settings/ Preferences (depending on which version of macOS you’re using), go to [your name] > iCloud > iCloud Drive and turn on ‘Sync this Mac’. On an iPad, iPhone or iPod touch, open Settings and tap [your name] > iCloud > iCloud Drive and tap ‘Sync this [Device]’. On a Windows PC, download iCloud for Windows, open it, select iCloud Drive then click Apply. Naturally, you can use iCloud Drive on iCloud.com, on any device with a web browser.
You can sync documents and folders found on your desktop using iCloud Drive. On your Mac’s iCloud settings, click iCloud Drive and turn on Desktop & Documents Folders. A folder called Desktop now appears in your mobile device’s Files app; files and folders on your Mac’s desktop are synced here. To find these items on another Mac, simply look for the Desktop & Documents folder in the iCloud Drive section of the Finder sidebar.
