How to check Mac’s free hard drive space

A modern MacBook now comes with a solid-state drive only with 128 GB of space, which means the “Your startup disk is almost full” error might usually appear if you store too much data. So, you’d better keep your hard drive nice and clean.

All you need is freeing up a bit of the disk space by deleting the apps that you don’t use anymore or rarely use. Once done, it’s better to check the hard drive space left.  If you don’t know how to do it on your Mac OS X, here’s how to check the free hard drive space.

There are five common ways to check the free hard drive space on your Mac. Let’s find out them

Method 1&2: Check From The Finder

The Finder offers two ways to check the amount of free disk space left on your Mac. They are very easy to follow.

Preview your device storage:

If you choose an item in the Finder and then press the spacebar key, there will be a preview of the item. So, you can use the preview feature to check the storage capacity. To do so

  • Click on the storage device on the Desktop. (To make it appear, navigate to Finder > Preferences > General, and modify the setting of Show these items on the Desktop.) You can also open a Finder window, under Devices heading and take look at the left column, choose the storage.
  • Press the spacebar and you will see a window showing the capacity of the storage as well as the available space.
  • In order to close the window, press spacebar again, or press Command + W, or click on the close-window icon.

Finder window status bar

If you like an overview of the free disk space left from the Finder, you should activate the Finder’s status bar.

  • Open a new Finder window by clicking on the Finder’s Dock icon or going to File > New Finder Window.
  • Click on the View menu, choose Show status bar and you will see how many items are in the current folder. In case you are viewing a folder on the hard drive, you will see your hard drive’s free space.

Method 3: About This Mac


In the later versions of macOS, you can easily check the disk usage in the About box.

  1. Launch Apple menu, and choose About This Mac.
  2. Click the Storage tab and check how much disk space left. (If your Mac is running OS X Mountain Lion or Mavericks, click on the More infoStorage)

Method 4: Get Info


Another way you can check is finding the hard drive in the Finder and then choosing it. If it displays in the Finder window sidebar or on the Desktop, click on the hard drive’s icon. If you don’t see your hard drive icon here, head to Go > Computer, and under Devices, click on the hard drive icon.

  • Click on the File menu, choose Get Info (or press Command + I on the keyboard).

The Info window will now show the capacity, the available space, and other information on your disk.

Method 5: From Disk Utility

The final way to check your free disk space is from the Disk Utility app. After that, click on the magnifying glass to open Spotlight, and search for Disk Utility in the box. Once you see the Disk Utility appearing in the list, hit the Enter key. You can also find the Disk Utility in Applications > Utilities.

Once it opens, simply choose your hard drive from the list. You will then see the capacity, the available space, as well as other information. With this method, you are also able to view the free space for any drive connected to your Mac such as a USB flash drive or the external hard drive.
