iCloud Photos automatically uploads and syncs all your images between all your Apple devices. It's a great backup solution, but it might be eating up your Mac's storage. Here's how to disable iCloud Photos on Mac.

On Mac, the iCloud Photos feature works by using the Photos app. If you enabled the iCloud Photos option when you first set up your Mac, it means that the Photos app stores a low-resolution version of all the photos in your iCloud account. It downloads new photos and videos in the background, even if you're not actively using the Photos app.

Given how it works, it's not uncommon for the photo library on your Mac to expand to 20GB or higher. And that's just space taken up by photos that you don't even use. You can reclaim the space by disabling the iCloud Photos feature on your Mac.

To do this, first, open the Photos app on your Mac. You can do this from the Dock or by using Spotlight Search.

Click Photos App Icon from Menu Bar

Then, click the "Photos" button from the top menu bar and choose the "Preferences" option.

Click Preferences From Photos in Menu Bar

Go to the "iCloud" tab and uncheck the "iCloud Photos" option.

Disable iCloud Photos on Mac

Your Mac will now stop uploading and downloading new photos from the iCloud service. It will continue working on your iPhone and iPad.

Even after you disable the iCloud Photos service, you might notice that photos that were downloaded on your Mac are still there.

In the Photos app, go to the "Library" tab and select the photos that you want to delete. Then, right-click and choose the "Delete Photos" button. Alternatively, you can use the Delete key on your keyboard.

Now, your Mac will delete all the media from the local storage.
