How to restore my MacBook data from iCloud?

Apple offers iCloud Backup for iPhones and iPads but not for Mac computers.

If you had data synced with iCloud on the old Mac, you can turn on the same sync options on a new Mac, using the same Apple ID for iCloud, and the data will sync with it. Sync options are at Apple menu > System Preferences > Apple ID > iCloud (in the Preferences sidebar). Also see the information below.

It is possible to sync data from a Mac to iCloud if you turn on those options (e.g., iCloud Photos, iCloud Drive including the Desktop & Documents option). Syncing has some of the benefits of a backup (and the benefit of being offsite) but is not the same as a backup. Major differences include the fact that not everything on your Mac can be synced and the fact that if you delete something, accidentally or otherwise, there is only a limited time period (30 days in most cases) during which it can be recovered.
