I can not find iCloud on my mac and it is not updating my email.

Hi Julia

Have you set up iCloud account yet?

Open System Preferences. Should be on your Dock, icon looks like a grey gear, or under the Apple icon on your Menu Bar.

Click on the iCloud tab.

Set up your iCloud Account if you haven't already using your Apple I.D.

Turn on all the services/apps you want to sync via iCloud like Mail, Photos, etc…

Give it a couple of minutes to upload any needed documents/data and then it should work.

Hope this helps, Greg
