iCloud Drive Upgrades
With the new iCloud Drive on macOS Sierra and iOS 10 you now have access to all of your important files faster, from anywhere.
With macOS Sierra installed the files you save to your desktop and your documents folder are available to you anywhere with iCloud.
That includes another Mac, your iPhone or iPad. There is no need to specifically save these in iCloud, just put them where you normally would. On OS X El Capitan you must specifically choose to save to iCloud.
