HOW DO I INSTALL ICLOUD ON MY MACBOOK?

Hi...

Your Mac must be running v10.7.2 Lion in order to setup an iCloud account.

Apple - iCloud - Learn how to set up iCloud on all your devices

iCloud: What if my device or computer doesn't meet iCloud system requirements?

When you post for help, please tell us which Mac OS X you have installed. Thanks 🙂

To get the full experience of iCloud, your MacBook must have the latest version of OS X Lion (10.7.3) running. If not, you can still use documents in the cloud, Find my iPhone, iCloud calendar, contacts in the cloud, and iCloud email through https://www.icloud.com/,and use your Apple ID to sign in.

I am using Mac OS X Lion 10.7.5. I've created an apple ID. When I go to icloud.com and enter my apple ID and password, it says "Your Apple ID must be used to set up iCloud on an iOS or OS X device before you can use iCloud.com." I was using my macbook when I logged in. Do I need to install Maverick?

Thanks!

Go to System Preferences>iCloud and sign in there.
