Manage iCloud storage on Mac
When you sign in with your Apple ID and turn on iCloud preferences, you automatically get 5 GB of free storage. Your iCloud storage is used for documents stored in iCloud Drive, iCloud Photos, iOS and iPadOS device backups, messages and attachments in iCloud Mail (your @icloud.com email account), and more. If you run out of space, you can upgrade your storage. You can also remove stored items to make more space available. See the Apple Support article How to free up storage space on your Mac.
View and manage iCloud storage
On your Mac, choose Apple menu
Click Manage, then do any of the following:
Upgrade your storage: Click Buy More Storage or Change Storage Plan, choose the amount of storage you want, then follow the instructions.
When you buy an iCloud storage upgrade, it’s billed to your Apple ID account. If you’re in a Family Sharing group and you use the same Apple ID to share family purchases, the upgrade is billed to the family organizer’s account.
See how an app or feature is using storage: Select an app or feature on the left, then read the usage information on the right.
Remove an iOS or iPadOS device backup: Click Backups on the left, select a device on the right whose backup you don’t need, then click Delete
(below the list of backups). If you don’t see Backups on the left, your iOS or iPadOS device doesn’t have iCloud backups.WARNING: If you delete the iCloud backup for your current iOS or iPadOS device, iCloud stops automatically backing up the device.
Turn off Siri and remove Siri-related data: Select Siri on the left, then click Disable and Delete.
Click Done.
Delete items from iCloud storage
You can permanently remove all documents and data for an app, remove documents individually, and also recover files you deleted from iCloud Drive in the last 30 days. You can save copies of documents before removing them from iCloud.
