The iCloud drive allows you to store documents and others files and access them remotely with ease. They can be accessed using any iOS device and also by logging onto icloud.com with your Apple ID. iCloud reduces the necessity to carry around files using devices and rather allows you to quickly edit a file on one device and access the saved version from another.
Here are steps to enable iCloud drive on Mac OS.
Step 1
Open ‘System Preferences’
Go to the bottom bar in your Mac and click on the ‘System Preferences’ button.

Step 2
Open the ‘iCloud Settings Window’
In the ‘System Preferences’ dialog box click on the ‘iCloud’ button.

Step 3
Enable ‘iCloud’ Drive
Now in the iCloud dialog box you will see a list of iCloud features and small boxes next to them that can be ticked. Find the ‘iCloud Drive’ option and ensure that the box corresponding to it is ticked.

Step 4
'Manage' Storage
You can click on the ‘Manage’ option at the bottom of the box to increase the storage capacity if needed by buying extra iCloud storage from Apple.

Step 5
Find the ‘Storage’ Folder
Open a finder window and you will notice a folder titled ‘iCloud Drive’ has been created and added to your quick navigation list. This is where all your iCloud files will be stored for quickly accessing via Mac.
Keep in mind that you need to have a working iCloud ID in order to use the iCloud drive services. You can create one by logging onto iCloud.com and entering your ‘Apple ID’.

By following these steps enable iCloud Drive on Mac OS X.
