How to Disable iCloud Photos on Mac
Apple
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.
