Each service lets you store data on the iCloud servers, and keep your Mac and all of your devices, including Windows and iOS devices, in sync. What You Need to Use the iCloud Service iCloud on the Mac requires OS X 10.7.2 or later. Or macOS Sierra or later. Once you have the proper version of OS X or macOS installed, you'll need to turn iCloud on. If you updated to OS X 10.7.2 or later after the launch of the iCloud service, the iCloud preferences pane will open automatically the first time you boot your Mac after updating the OS.
