In this tutorial, we will guide you on how to free up system storage on your Mac. Over time, your Mac’s storage can become cluttered with unnecessary files, which can slow down your system and reduce its overall performance. By following the steps below, you can reclaim valuable disk space and ensure that your Mac runs smoothly.

1. Delete Unnecessary Files

Start by identifying and removing any unnecessary files from your Mac.

These files may include old documents, downloads, and duplicates that are taking up valuable disk space. To do this:

  • Step 1: Open Finder.
  • Step 2: Go to the “Documents” folder and delete any files you no longer need.
  • Step 3: Navigate to the “Downloads” folder and remove any unneeded files.
  • Step 4: Use a duplicate file finder app to identify and delete any duplicate files on your system.

2. Clear Cache

Your Mac stores temporary files in its cache to speed up operations.

However, over time, these cache files can accumulate and take up a significant amount of storage space. Follow these steps to clear cache:

  • Step 1: Open Finder.
  • Step 2: Click on “Go” in the menu bar and select “Go to Folder”.
  • Step 3: Type “~/Library/Caches” without quotes in the box that appears and press Enter.
  • Step 4: Select all the folders inside the “Caches” folder and move them to the Trash.

3. Remove Unused Applications

Unused applications can take up a significant amount of storage space on your Mac. Follow these steps to remove them:

  • Step 1: Open Finder.
  • Step 2: Go to the “Applications” folder.
  • Step 3: Drag any unused applications to the Trash.
  • Note: Some applications may require additional steps for complete removal, so make sure to check the developer’s instructions if needed.

4. Optimize Storage

Your Mac has a built-in feature called “Optimize Storage” that helps you manage available disk space. Follow these steps to enable it:

  • Step 1: Click on the Apple logo in the top-left corner of your screen and select “About This Mac”.
  • Step 2: In the window that appears, click on “Storage”.
  • Step 3: Click on “Manage” and then select “Optimize”.
  • Note: You can also enable options like automatically emptying Trash, reducing clutter, and storing files in iCloud.

5. Use External Storage

If you have large files or folders that you don’t use regularly, consider moving them to an external storage device.

This can help free up a significant amount of space on your Mac’s internal storage. Simply connect an external hard drive or use cloud storage services to transfer and store your files.


By following the steps outlined in this tutorial, you can effectively free up system storage on your Mac. Remember to regularly clean up unnecessary files, clear cache, remove unused applications, optimize storage, and utilize external storage devices as needed. These practices will not only improve your Mac’s performance but also ensure that you have ample disk space for future use.
