Backing your iPhone or iPad to iCloud, and backing up photos on your Mac, can be very useful. It makes it easy to recover data in the event of a catastrophic problem with your device and means you never have to worry about losing your precious photos.

In addition, individual apps on your Mac can use iCloud to store data to make it available on multiple devices. However, there may be occasions when you need to turn off iCloud backup. Perhaps your iCloud storage is nearing its maximum limit, or you have switched to a different backup strategy. In this article, we’ll show you how to stop iCloud backup on a Mac and an iOS device.

How to stop iCloud backup on your Mac

Unlike an iPhone or iPad, your Mac doesn’t back up all of its files to iCloud. Instead, Apple’s recommended solution for backing up your Mac is to use Time Machine with either a directly-connected hard drive or SSD or a compatible network drive like Time Capsule. However, Photos on your Mac stores images in iCloud if you use iCloud Photo Library, and various apps use iCloud to store files and data.

How to stop apps using iCloud

  1. Go to the Apple menu and go to System Settings > Apple Account > iCloud.
  2. Click See All > iCloud Drive > Apps syncing to iCloud Drive.
  3. Scroll through the list of apps in the next window and disable those you don’t want to store data on iCloud.
  4. Quit System Settings.

Note: Switching off iCloud for apps may impair the app’s performance. You should check the app’s website and ensure that it will continue to work properly before you uncheck the box.

How to disable iCloud Photo Library

If you take lots of photos, storing them in iCloud is going to use several gigabytes of disk space. For most of us, that means paying for extra storage. While the cost of extra iCloud space is relatively small, you may want to stick with the 5GB we all get for free. And so, you might need to turn off iCloud Photo Library.

To turn off iCloud Photo Library on a Mac:

  1. Open the Photos app.
  2. Press Command-Comma to launch Photos Settings.
  3. Go to the iCloud tab and deselect the checkbox next to iCloud Photos.

That will stop your Mac from using iCloud Photo Library, but it won’t stop photos you take on your iPhone or iPad from backing up to iCloud.

To stop photo backup to iCloud for all devices on your account, do the following:

  1. Go to System Settings > Apple Account > iCloud.
  2. Click See All > Photos
  3. Disable iCloud Photos by switching the toggle next to Sync this Mac.

That will disable iCloud Photo Library altogether. You have 30 days after clicking the button to download your photos, after which your photographs will be deleted from iCloud.

If you want to free up space used by the Photos app on your Mac, as well as in iCloud, CleanMyMac can help. It comes with a smart My Clutter feature that can find similar and duplicate images. Here’s how to use it: 

  1. Get started with a free CleanMyMac trial.
  2. Open the app and go to My Clutter from the sidebar. 
  3. Run a scan and click Review All Files.
  4. Sort through Duplicates, select images for deletion, and click Remove. 
  5. Repear for Similar Images.

To free up even more space, delete unneeded large and old files using the same feature or remove junk files using the Cleanup tool.

How to turn off iCloud completely on a Mac

Turning off iCloud altogether will significantly affect how you use your Mac. You won’t be able to use iCloud Drive or any app that stores files in iCloud. In addition, you won’t be able to sync Reminders, Contacts, Calendar entries, Keychain items, or Safari Bookmarks. And features like Handoff and Universal Clipboard won’t work. So, think carefully before you do it. Still want to go ahead? Here’s what to do.

  1. Go to System Settings > Apple Account.
  2. Click Sign Out at the bottom left of the window and follow the on-screen instructions.

How to turn off iCloud backup on an iPhone

  1. Launch the Settings app.
  2. Tap your name at the top of the screen.
  3. Tap iCloud.
  4. Scroll down to iCloud Backup and tap it.
  5. Toggle the Back Up This iPhone switch to the off position > Turn Off.

Your iPhone will no longer back up to iCloud. That means if you lose it, you’ll lose all the changes to data that have taken place since the last backup.

The process for turning off iCloud backup on an iPad is the same as for an iPhone.

Using this method, you’ll still be able to sync data from Reminders, Calendar, and other apps with iCloud. And iCloud Keychain, Universal copy and paste, and Handoff will all work. In addition, any apps that store data in iCloud will continue to work as usual.

If you want to prevent specific apps from using iCloud to store data, here’s what to do:

  1. Open the Settings app on your iPhone or iPad.
  2. Tap your name, then tap iCloud > See All.
  3. Scroll through the list of apps and toggle the switch next to the ones you want to stop using iCloud to the off position.

To log out of iCloud altogether, go to Settings > Apple Account and tap Sign Out. This will have the same effect as it does on the Mac described above.

There are a number of different ways to turn off iCloud backup, depending on whether you want to prevent individual apps from using it, stop an iOS device from backing up to iCloud, or sign out of iCloud altogether. Make sure you read the above carefully and choose the method that suits your needs in order to prevent your Mac or iOS device from losing the functionality you want to keep.
