How to check disk space on Mac 3 different ways
In this age of terabyte flash drives and cloud storage, it’s easy to forget that storage space is finite. But it is, and as software gets more sophisticated, must-have apps become more plentiful, and more content than ever is downloaded to computers, you can eat through a 1TB SSD in no time at all.
Sure, in theory, if your Mac hard drive gets full, you can just upgrade, but at around $1,000 for a 2TB iMac SSD and $1,600 for a 4TB SSD, neither option is exactly affordable. Plus, it won’t work for all Mac models since most of them are not upgradeable.
For optimum performance, you should continually monitor Mac hard drive space to make sure there’s always room for your next big download. Keep reading to learn how to find storage on your Mac and use it more efficiently.
Сheck Macbook storage via About This Mac
The simplest way to check Mac hard drive space is by accessing About This Mac.
- Click on the Apple icon and choose About This Mac.
- Click More Info > Storage Settings.
The Storage tab will show you how much space is being taken up by System Data, Documents, Apps, and more. It will also display available space.
Note: If you’re running an older macOS version, you may not need to click More Info to find the Storage option. You will have the Storage tab in the window that opens.
Сheck Mac storage via Disk Utility
Another option available for Mac users is checking storage via Disk Utility. It is a built-in app that helps manage both internal and external storage devices, format and reformat them, and solve some issues that may emerge with hard drives.
Here’s how to use it to check Mac storage:
- Open the Finder and go to Applications.
- Navigate to Utilities > Disk Utility. Alternatively, you can open it via Launchpad or ask Siri to do that for you.
- Click Macintosh HD from the sidebar, and you will see how much storage is used and how much of it is still free.
Note, though, that this overview is general. Meaning that if you want a more detailed insight into what is taking up space on your Mac, it is better to access storage information via About This Mac.
Сheck Mac storage via Finder
You can also use the Finder app to find out how much available storage your Mac still has. The Finder is an app that organizes all your data, such as applications, media, documents, folders, and any other files. It can also help get information about hard drives, and it is what we need in this case.
Here’s how to check Mac storage via the Finder:
- Click the Finder icon from the Dock.
- Under Locations from the sidebar, click Macintosh HD.
- Now, press Command + I.
- In the Info window that opens, click General to see capacity, available, and used storage.
Alternatively, you can control-click or right-click Macintosh HD and navigate to Get Info.
Like with the Disk Utility, this method provides a general overview of Mac storage.
