4. Clear your internet cache

Your internet browser stores copies of web pages you visit (called a cache), which allows pages to load faster when you revisit them. Go to your browser’s settings to delete your cache and free up space. The Settings location varies depending on your browser.

How to free up disk space with built-in Mac tools

Apple also has some storage management tools that come pre-installed on your Mac. To locate them, follow these steps:

1. Open the Apple menu from the Finder bar and select “About This Mac.”

2. Click the “Storage” tab and then select “Manage.”

3. Click “Recommendations” in the left navigation pane.

From here, you can:

  • Customize storage for iCloud (such as which files will automatically be stored to iCloud instead of your computer).

  • Select how to optimize storage (such as automatic deletion of shows you’ve watched).

  • Opt to automatically empty your Trash.

  • Further reduce clutter by sorting through large files and apps individually, then deleting them.

Cloud storage options

One of the best ways to avoid a cluttered hard drive is to store your files on a cloud server. This also ensures the safe storage of your documents and files on something other than your device, which means your data (and memories!) are safe even if your computer crashes or is lost or damaged. Check out some of the best cloud storage solutions on the market, and rest easy knowing that your files are safe.
