iCloud: Set up iCloud
To use iCloud, you first need to set it up on an iOS device or a Mac. After the initial setup, you can turn on iCloud on your other devices and Mac computers, your Apple Watch, and your Apple TV.
Set up iCloud for the first time
Do any of the following:
On your Mac: Choose Apple menu > System Preferences, click iCloud, enter your Apple ID and password, then turn on the features you want to use.
On your iOS device: Tap Settings > [your name] > iCloud (or Settings > iCloud), enter your Apple ID and password, then turn on the features you want to use.
If you don’t have an Apple ID, follow the onscreen instructions to create one.
After the initial setup, use the same Apple ID (and follow the same instructions) to sign in to iCloud on your other iOS devices and Mac computers. To sign in on your Windows computer, see the instructions below. For information about signing in to iCloud on Apple TV, see the Apple TV User Guide.
Note: If you don’t have an iOS device or a Mac, go to iCloud.com on your Windows computer, then enter your Apple ID and password to turn on web-only access to Notes, Contacts, Pages, Numbers, and Keynote.
Set up iCloud on a Windows computer
After you set up iCloud on your Mac or iOS device, you can set it up on a Windows computer.
Go to the Apple Support article Download iCloud for Windows.
Follow the instructions to download and install iCloud for Windows.
Enter the Apple ID and password you used to set up iCloud on your Mac or iOS device.
Turn on the features you want to use, then click Apply.
If you have Microsoft Outlook 2016 or earlier installed, Outlook shares data with the following apps:
Reminders (called Tasks in Outlook)
To use other iCloud apps, or if you don’t have Outlook installed, use the apps on iCloud.com.
You can also keep the Safari bookmarks on your iOS devices and Mac up-to-date with your bookmarks on Google Chrome or Mozilla Firefox on your Windows computer.
