Freeing Up Disk Space on Mac: Ultimate Guide

If you're a Mac user, you've probably encountered the dreaded "Your disk is almost full" notification. This message is not only annoying but can also slow down your system and hinder your productivity. But don't worry, we've got you covered. This guide will walk you through various methods to free up disk space on your Mac, ensuring your device runs smoothly and efficiently.

Understanding What's Eating Up Your Disk Space

Before you start deleting files and applications randomly, it's essential to understand what's taking up your disk space. Mac has a built-in tool that provides a breakdown of your storage usage. This will help you identify the significant space hogs and decide the best course of action.

To access this feature, click on the Apple icon at the top left corner of your screen, select 'About This Mac', and then click on 'Storage'. Here, you'll see a bar that divides your storage into categories like Apps, Documents, System, and Other.

Interpreting the Storage Categories

Each category in the storage breakdown represents different types of files. 'Apps' include all the applications installed on your Mac. 'Documents' comprise of files like PDFs, spreadsheets, and text files. 'System' includes the operating system and system files necessary for your Mac to function. 'Other' is a bit of a catch-all category, including cache files, temporary files, and system backups.

By understanding these categories, you can make informed decisions about what to delete or move to free up disk space.

How to Free Up Disk Space

Now that you've identified what's taking up your disk space let's look at various ways to free up some room.

Empty the Trash: It may seem obvious, but many people forget to regularly empty their Trash. Files in the Trash still take up disk space. To empty the Trash, right-click on the Trash icon in your dock and select 'Empty Trash'.

Delete Unnecessary Apps: Apps can take up a significant amount of space. Go through your Applications folder and uninstall any apps you no longer use. To uninstall an app, drag it to the Trash or use a third-party uninstaller to remove all associated files.

Clear Cache Files: Cache files are temporary data stored by apps to speed up processes. Over time, these files can accumulate and take up a lot of space. You can delete these files manually or use a cleaning utility to do it for you.

Remove Old iOS Backups: If you've been backing up your iPhone or iPad to your Mac, these backups can take up a lot of space. You can delete old backups via iTunes or Finder, depending on your macOS version.

Advanced Methods to Free Up Disk Space

If you've tried the methods above and still need more space, here are some advanced techniques to consider.

Store in iCloud: MacOS offers a feature called 'Store in iCloud' that moves files from your Desktop and Documents folders to iCloud. This can free up a lot of space, but keep in mind that you'll need to pay for iCloud storage if you exceed the free 5GB limit.

Optimize Storage: 'Optimize Storage' is another macOS feature that automatically removes movies and TV shows you've watched and only keeps recent email attachments. This feature can be a real space saver if you consume a lot of media on your Mac.

Use a Third-Party Disk Cleaning App: There are many third-party apps available that can help you clean your disk and maintain your Mac. These apps can find and remove duplicate files, clean up cache files, and even uninstall apps properly.


Freeing up disk space on your Mac doesn't have to be a daunting task. By understanding what's taking up space and using the methods outlined in this guide, you can easily free up disk space and keep your Mac running smoothly. Remember, regular maintenance is key to a healthy and efficient Mac.
