Checking Disk Space on Mac: 6 Methods

As a Mac user, it's essential to keep track of your disk space. Over time, files and applications can accumulate, eating up storage and slowing down your system. Fortunately, there are several ways to check disk space on your Mac, each with its own advantages and benefits. In this guide, we will explore six different methods to help you manage your storage effectively.

About This Mac

The first and perhaps most straightforward method to check disk space on your Mac is through the "About This Mac" feature. This built-in tool provides a quick overview of your system, including the amount of disk space used and available.

To access this feature, click on the Apple icon in the top-left corner of your screen, then select "About This Mac". From there, click on the "Storage" tab. Here, you'll see a bar that visually represents your storage usage, divided into different categories such as apps, documents, and system.

While this method is easy and convenient, it doesn't offer a detailed breakdown of your files. If you need more specific information, you might want to consider the following methods.

Disk Utility: Disk Utility is another built-in tool that provides more detailed information about your disk space. It shows the total capacity of your drive, how much space is used, and how much is available.

To use Disk Utility, open your Applications folder, then navigate to the Utilities folder. From there, open Disk Utility. Select your hard drive from the sidebar, and the information will be displayed at the bottom of the window.

While Disk Utility is more detailed than "About This Mac", it still doesn't provide a breakdown of individual files and folders. For that, you'll need to use a different method.


The Finder is a powerful tool for managing files on your Mac. It can also be used to check the size of individual files and folders.

To do this, open Finder and navigate to the file or folder you want to check. Click on the file or folder to select it, then press Command-I to open the Get Info window. Here, you'll see the size of the file or folder.

This method is useful for checking the size of specific files and folders, but it can be time-consuming if you need to check multiple items.

Terminal: If you're comfortable with using the command line, you can use Terminal to check disk space on your Mac. This method provides a detailed breakdown of your storage usage, including hidden files and system files.

To use Terminal, open your Applications folder, then navigate to the Utilities folder. From there, open Terminal. Type "df -h" and press Enter. This command will display your disk usage in a human-readable format.

While Terminal provides detailed information, it can be intimidating for users who are not familiar with the command line.

Third-Party Apps: There are many third-party apps available that can help you manage your disk space. These apps provide a visual representation of your storage usage, making it easy to identify large files and folders.

Some popular disk space management apps include DaisyDisk, Disk Inventory X, and OmniDiskSweeper. These apps scan your hard drive and display your files and folders in a graphical format, allowing you to quickly identify and delete unnecessary files.

While these apps can be helpful, they often come with a cost. If you're looking for a free solution, you might want to stick with the built-in tools or Terminal.

iCloud: If you're running low on disk space, one solution is to store your files in iCloud. This allows you to access your files from any device, and it can free up a significant amount of space on your Mac.

To use iCloud, open System Preferences and click on iCloud. From there, you can choose which types of files to store in iCloud, including photos, documents, and desktop files.

Keep in mind that iCloud comes with a monthly cost, depending on how much storage you need. However, it can be a convenient solution if you frequently use multiple devices.


In conclusion, there are many ways to check disk space on your Mac. Whether you prefer a simple overview or a detailed breakdown, there's a method that will suit your needs. By regularly checking your disk space and deleting unnecessary files, you can keep your Mac running smoothly and efficiently.
