How to check storage on mac

Last Updated: Mar 7, 2024 by

If you’re a Mac user, you may have noticed that your computer’s storage space seems to fill up quickly. This can be frustrating, especially if you’re constantly receiving notifications that your storage is almost full. But before you start deleting files and applications, it’s important to understand how to check your storage on Mac and optimize it for efficiency. In this article, we’ll discuss some simple steps you can take to check and manage your Mac’s storage.

Checking Your Storage

The first step in managing your Mac’s storage is to check how much space you have available. To do this, click on the Apple icon in the top left corner of your screen and select “About This Mac.” Then, click on the “Storage” tab. This will show you a breakdown of how much space is being used by different categories such as Applications, Documents, and System. You can also click on “Manage” to get more detailed information about your storage usage.

Storage Optimization

One of the easiest ways to free up space on your Mac is to optimize your storage. This feature, available on macOS Sierra and later, automatically removes files that you don’t need, such as old email attachments, temporary files, and items in your trash. To enable storage optimization, go to “About This Mac” and click on the “Storage” tab. Then, click on “Manage” and select “Optimize Storage.” You can also customize which files are removed by clicking on “Review Files.”

Uninstall Unused Applications

Another way to free up space on your Mac is to uninstall applications that you no longer use. To do this, go to your “Applications” folder and drag any unwanted applications to the trash. You can also use a third-party application such as AppCleaner to completely remove all associated files. This will help to free up space and improve the overall performance of your Mac.

Use Cloud Storage

If you have a lot of large files, such as photos and videos, taking up space on your Mac, consider using cloud storage services such as iCloud, Google Drive, or Dropbox. These services allow you to store your files in the cloud, freeing up space on your computer. You can also access these files from any device with an internet connection.

Empty Your Trash

It’s easy to forget about the items in your trash, but they can take up a significant amount of space on your Mac. To empty your trash, simply right-click on the trash icon in your dock and select “Empty Trash.” You can also set your Mac to automatically empty your trash every 30 days by going to “Finder,” then “Preferences,” and selecting “Advanced.”


By following these simple steps, you can easily check and manage your Mac’s storage for optimal efficiency. Remember to regularly check your storage and remove any unnecessary files or applications to keep your Mac running smoothly. With these tips, you can make the most out of your Mac’s storage space and avoid those pesky “storage almost full” notifications.
