macOS can help make more room on your Mac by optimizing its storage. When space is needed, it keeps files, photos and videos, Apple TV movies and shows, and email attachments in iCloud and makes them available on demand. Files don’t take up space on your Mac, and you can download the original files when you need them. Recent files and optimized versions of your photos are always on your Mac.
Choose Apple menu > About This Mac, click Storage, then click Manage.
macOS calculates how much space is being used by different categories.
Note: Wait until all categories are finished being calculated to ensure you’re seeing the accurate amount of space. Values are refined as each category is calculated.
View the recommendations and decide how to optimize storage on your Mac.
