Set up iCloud on an iOS device, iPadOS device, Mac, or Windows computer
To use iCloud, you first need to set it up on an iOS device, iPadOS device, or Mac. After the initial setup, turn on the features you want to use on each of your iOS devices, iPadOS devices, and Mac computers; and your Apple TV.

Do any of the following:
On your iOS or iPadOS device: Go to Settings, tap “Sign in to your [device]”, enter your Apple ID and password, then turn on the features you want to use.
On your Mac: Choose Apple menu
> System Preferences, then do one of the following:macOS Catalina 10.15: Click Apple ID, enter your Apple ID and password, then turn on the features you want to use.
macOS 10.14 or earlier: Click 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 your other iOS devices, iPadOS devices, and Mac computers. To sign in on your Windows computer, see the instructions below. For information about signing in on your Apple TV, see Set up your Apple ID on Apple TV in the Apple TV User Guide.
Note: If you don’t have an iOS device, iPadOS device, or Mac, go to iCloud.com, then enter your Apple ID and password to turn on web-only access. If you sign into iCloud.com with web-only access on a tablet browser, you can use iCloud Drive, Notes, and Contacts.
Set up iCloud on a Windows computer
After you set up iCloud on your iOS device, iPadOS device, or Mac, you can set it up on a Windows computer.
If you have Microsoft Windows 10 May 2019 Update, Build 18362.145 KB4497935 (or later), get the iCloud for Windows app from the Microsoft Store.
If you have an earlier version of Microsoft Windows, do the following:
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 iOS device, iPadOS device, or Mac.
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:
iCloud Mail
Contacts
Calendar
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, iPadOS devices, and Mac up-to-date with your bookmarks on Google Chrome or Mozilla Firefox on your Windows computer.
Note: Some iCloud features have minimum system requirements. iCloud may not be available in all areas, and iCloud features may vary by area. See the Apple Support article System requirements for iCloud. For information about features, go to apple.com/icloud/.
