How to Clear Cache and Cookies on a Mac (9.73 GB Gone!)


It’s no secret that you can free up a lot of space on a Mac® hard drive simply by clearing the cache.

In fact, I managed to clear an enormous 9.73 GB of cache and cookies on my Mac just before I wrote this post.

The best part? You don’t have to be a computer guru to do the same. All it really takes is a few clicks to drastically optimize the hard drive.

It’s worth your time to dig a little bit deeper into why and when we need the cache—and when it’s time to get rid of it.

In this post, we’ll tell exactly what you need to know about this technology and provide a step-by-step guide on how to clear cache.

To get started, I want to show you how cache actually works, and why you should start optimizing it immediately.

 

What Is Cache and Why Do We Need It?

Simply speaking, cache is a collection of data that duplicates the original information you processed on your computer. Whenever you use any application, your Mac will store some sort of data in order to (potentially) request it faster in the future. As an example, these could be temporary files (such as images and HTML documents) created by a web browser or instant messenger (including Facebook, Twitter, Instagram and Skype).

If a user edits a lot of photos and videos, he may notice that the editor also saves temporary data on the hard disk. Video editors with the function of displaying applied effects during editing don’t always delete such files at the end of work—and the hard drive starts to explode in size.

Besides the obvious desire to clean up disk space, there may be other reasons for deleting caches, including:

If you need to clear all cache files with just one click, download a free trial of Parallels® Toolbox Disk and System Pack. The software will evaluate your log files, cache, trash, browser data, mail cache, mobile apps, and updates—and instantly delete them per your request.

If you want to do that manually, follow the steps below.

 

How to Clear System Cache in macOS

Step 1: Terminate all running applications using the Cmd+Q key combination.

Step 2: Open a Finder window and use Shift+Cmd+G to navigate to the directory

~/Library/Caches.

Step 3: Manually open every folder, select all the files using Cmd+A, and move everything to the Trash. If required, enter your password.

Note: It’s not advisable to delete cache folders. Keep them to avoid any system conflicts and only delete the files inside.

Step 4: Once again, using the Shift+Cmd+G key combination, go to the folder

~/Library/Caches.

Step 5: Do the same thing—manually delete all files inside each folder there.

Step 6: Reboot. The first time the system boots may take a little longer than usual. This is normal.

If there are multiples user accounts in the system, you have to repeat the same steps for each of them.
