Part I: Introduction

Have you noticed that your Mac device is becoming too slow? Are you in the middle of a task and your Mac completely freezes out? Some people experience a very slow Mac device and this can be very frustrating.
 
Although Mac devices are very powerful computers, they can sometimes slow down because of a variety of reasons. One reason for a slow Mac device is the use of too much memory.

Another is a full storage space. When there are a few spaces on your hard disk, this means there is less space allocated for performing tasks efficiently.
 
And one of the biggest culprits of a fully occupied hard disk is the adding up of cache. So what is this cache and how does it affect your Mac device?

Part II: What Is Cache?

To give you a better user experience, cache files are put into storage by your system and its applications. Browser stores cache files too.

The said cache files can be of various types such as images, documents, videos, etc. And they are stored in order for processes to speed up.
 
One example would be the browser Safari. It downloads and saves images on a particular web page you visit and stores it as the cache.

In this way, the next time you visit that specific page, you don’t have to re-download the images all over again. It makes the process faster.
 
After some period of time, cache files increase in size significantly. Although cache files are actually temporary and they can be deleted, most people forget to actually remove them.

That’s why cache files take up a significant part of your hard disk drive and it leads to the slowing of your Mac device.

Cache files include application cache, system cache, library cache, browser cache, and a whole lot more.

Different types of the operating system store their cache in various different folders of the computer. However, the macOS puts cache files inside the cache location.
 
The primary use of cache is to enhance the experience of the user. However, the build-up of these cache files can result in a full disk drive. They are relatively small in size.

However, if it takes too long for you to delete these cache files they can grow considerably larger.
 
When this happens, your system is left to use a little amount of space in order to operate. Thus, the smooth performance of your Mac device is affected.

Thus, to ensure that you regularly have a great user experience on your Mac device, it is important for you to remove cache often.
 
The Mac device is relatively difficult to clean compared to others. This is because destination folders can be found under multiple folders and files.

Thus, if you do not have the knowledge to use your Mac, you might be wondering how to clean the cache properly.

System cache is composed of files put into storage by system applications that are running in the background of your Mac operating system.

App cache is composed of downloaded media files of applications that are there to make it operate faster. It is also composed of temporary download files, system thumbnails, etc.

Although these files are very useful for the app, they can take up a large amount of space and it is necessary to clean them up.

After which, you should find the folder with the app’s name within it. Delete all the files contained in this folder.
