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.
