the Icloud and i tun in APPLE can be used to synchronous data or no
icloud and I tune
Yes. Apple has iCloud preconfigured to synchronize your account settings between systems. They also provide a framework to allow applications to sync their data as well, but it is up to the software authors to use it. For applications that don't use iCloud sync, you can always store your files in the iCloud folder to manually sync them. You can also enable synchronizing your desktop and documents folders by navigating to
System Preferences -> Internet Accounts -> iCloud -> iCloud Drive -> Optionsand checking the box by "Desktop & Documents Folders"
