iCloud setup, in and of itself, is trivial—you enter your Apple ID and password, and maybe click a few buttons, on each of your devices. There’s no software to install on a Mac or iOS device (assuming you already have a recent version of the operating system) and only a few options you can turn on or off. You have to go through a few more steps, but only a few, under Windows.

However, if you were previously a MobileMe member but didn’t migrate to iCloud before MobileMe was turned off—or if you migrated only your email—you’ll need some additional information.

If you’ve already set up iCloud, you can skim most of this chapter, starting with Set Up iCloud on a Mac—just to make sure you’ve enabled all the features you may want to use. But everyone should know how to Navigate the iCloud Web Site; I return to specific parts of the site as the book progresses.
