Thanks to iCloud, Apple's web-based data storage and syncing service, sharing data like contacts, calendars, emails, and photos across multiple computers and devices is easy. With iCloud enabled on your devices, each time you connect to the internet and make changes to iCloud-enabled apps, those changes will automatically upload to your account. iCloud will then share the updates to your compatible devices.

With iCloud, keeping data in sync is as simple as setting up each of your devices to use your iCloud account.

To use iCloud, you need an Apple ID. These instructions apply to iTunes 10.5 and higher, Mac OS X 10.7.5 or later, Windows Vista or 7 or higher, and devices running iOS 5 and later. To use the web-based iCloud apps, you'll need at least Safari 5, Firefox 21, Internet Explorer 9, or Chrome 27.

How to Set up iCloud on Mac OS X

To set up iCloud on a Mac, there's very little you need to do because the iCloud software is part of the operating system. As a result, you don't need to install anything.

Here's what to do:

  1. To access your iCloud settings, click on the Apple menu in the top left corner and choose System Preferences.

How to Set up iCloud on Windows

Here's how to set it up.

  1. Open the Microsoft Store on your PC.

Set up & Use iCloud on iOS Devices

All iOS devices running iOS 5 or higher have iCloud. You don't need to install any apps to sync data across your computers and devices.

You do need to configure the features you want to use, however. Here's how to set up iCloud on mobile devices.

  1. Open the Settings app.

  2. Tap your name at the top of the screen.

  3. Select iCloud.

  5. Move the slider to On/green for each feature that you want to enable.

  6. At the bottom of the screen, tap the iCloud Backup menu.

  7. If you want to back up the data on your iOS device to iCloud (this is great for restoring from backup wirelessly via iCloud), move the iCloud Backup slider to On/green.

  8. Using iCloud to sync data between your computers and devices means you have a backup of your data available at all times. You can not only back up data there but also restore backed-up data over the Internet. All iCloud users get 5 GB of storage for free. You can upgrade for more space for an annual fee.

Programs That Back up to ICloud

The following programs include iCloud backup features. For most of them, you just need to turn the backup feature on to have their contents uploaded to iCloud.

Other apps are also iCloud compatible. Check the options pages on your platform for a complete list.

  • MacOS/iOS apps: Safari (for bookmarks); Mail; Address Book; Calendar; Notes; Messages; Home; Health; Wallet; Reminders; Pages, Keynote, and Numbers 1.5 or higher; and Photos
  • Windows apps: Safari (for bookmarks); Photos; Mail

Checking Your iCloud Storage

To find out how much of your 5 GB iCloud backup space you're using and how much you have left:

  • On Mac and Windows: Open the iCloud Preferences. The bar across the bottom shows how much you're using and how much is available.
  • On iOS: Tap the Settings app and then tap iCloud. Tap Storage & Backup. Look for the Storage menu.

Managing iCloud Backups

If your iCloud storage is filling up and you don't want to pay for the upgrade, you can clear some space on it. Here's how.

  1. Return to the iCloud screen on any platform and click or tap Manage.

  2. The next screen shows a list of all of the apps that use space in your iCloud account. Click one to see how much room it's taking, and click Delete Documents and Data to remove it.

    Deleting an app's data doesn't stop it from uploading more. Remove the permission from the Settings menu to prevent it from taking up space in the future.

Upgrading iCloud Storage

To add more storage to your iCloud account, access your iCloud software and select an upgrade.

On Mac and Windows, click Buy More Storage in the iCloud management window. Select the upgrade you want and then click Next. Enter your Apple ID password and click Buy to upgrade.

If you're already paying for extra iCloud space, the button will say Change Storage Plan.

Upgrades to your iCloud storage charge monthly via your iTunes account.
