How to Clear Cache on Mac – A Complete Guide

What is Cache on Mac?

A cache is a type of temporary memory used to collect temporary data to help your system, browser, and applications load faster in the future. For example, when you browse a website, your browser downloads HTML files, images, videos, Java scripts, etc. and stores them in a cache folder. Next time you visit the site again, your browser will load the data through the stored cache files without connecting to the network. 

Common cache files include system cache, application cache, and browser cache.

Why Should You Clear Cache on Mac?

Caches can speed things up on your Mac. However, too many of them will not only take up a lot of your valuable storage space but also degrade your Mac performance. Therefore, it is necessary for you to clean them once in a while. Deleting the cache has many benefits, such as freeing up storage space, correcting webpage errors, preventing tracking by malware and third-party software, forcibly deleting outdated content in applications, and so on.
