iCloud: the essential guide

Poor old MobileMe. It tried hard, but never quite delivered. Expensive, sometimes slow and saddled with a clumsy name, it has long had the air of an unloved child.Its development cycle was long and drawn out. And by the time Steve Jobs announced the end of its short and undistinguished life, just two years after its rebirth from the ashes of .Mac, few were inclined to shed any tears.Yet it wasn't all bad. The email service was stable and largely dependable. It synced our contacts, so we didn't need to tap them all in on an iPhone keyboard, and the calendar tool always made sure we turned up on time, wherever we happened to be.Apple knew this as well as anyone, which is why it chose to preserve those parts, jettisoning the web publishing, photo gallery and iDisk, as it set about building iCloud.Housed in a vast data centre in North Carolina, iCloud is Apple's next-generation online service. It syncs your iPhone, iPad, Mac and iPod touch. It can track a lost device, copy your iPhone snaps over the web so they're safely backed up on your Mac, and synchronise your iWork files so that whatever device you're using, downtime is never wasted time.Over the next few pages, we'll show you how to set up your Mac and iOS devices to use iCloud, how to sync your apps and data, and how easy it is to back up your documents to the web. You'll soon see that MobileMe's demise really was the iCloud with a silver lining. Whether you're moving an existing MobileMe account to iCloud or setting it up for the first time, Apple has applied its trademark logic to the process to make it as simple as possible.The most important step you need to take is to make sure all of your devices are up to date and running the most recent versions of each headline app. Here we'll walk you through the process, step by step. Update your Mac To take advantage of all of iCloud's features you need to be running OS X Lion. This is now well bedded in and although some older machines appear to run a little slower than they did under Snow Leopard, it's generally proved to be fault free and enjoys good compatibility with existing third-party hardware and software.iCloud requires Lion version 10.7.2 or later, which is the version currently being shipped through the App Store (£21). If you upgraded to Lion when it shipped back in July and haven't touched it since then, run Software Update now to downloaded the latest revision before going any further. Lion only works on Macs running on an Intel Core 2 Duo, Core i3, i5 or i7, or Xeon processor. That precludes the earliest Intel Macs and anything running a PowerPC processor. It requires a minimum of 2GB of RAM, 7GB of hard drive space and Mac OS X 10.6.6 or later. This was the first version of the OS released via the Mac App Store, through which the 4GB installer must be downloaded.If you're on a capped broadband deal or you don't have broadband, then all is not lost. Head for a bricks-and-mortar Apple Store if you have one within reasonable driving distance and download it there using the free Wi-Fi. It's over twice the price of the downloaded edition, but it does come on one of the best-looking thumb drives we've ever seen. One of the most exciting features of iCloud is Photo Stream, which automatically copies the 1,000 photos you've most recently taken over the last 30 days between your iPhone, iPad and iPod touch, as well as backing them up to any Mac running iPhoto or Aperture.Again, you'll need to ensure that you're running the very latest edition of either of these applications. In the case of iPhoto, that's iPhoto 11 version 9.2 or later, while Aperture users should be running version 3.2 or later.Both of these are available through the Mac App Store (iPhoto 11 costs £10.49; Aperture 3 costs £55). Update iTunes iCloud has taken over from MobileMe as the main synchronisation conduit for all of your data on Apple's integrated ecosystem. That includes not only your contact, email accounts, calendars and so on, but also your purchases through the iTunes Store, iBook Store and Mac App Store.That means that any purchase you make on any of your devices, or through iTunes on your Mac, will automatically be synchronised on each of your other devices. This works on your iPhone, iPad and iPod touch as soon as you upgrade to iOS 5 and activate iCloud.But to get the Mac side of things working you need to upgrade to iTunes 5 or later, again through Software Update.
