Introduction to Different Kinds of Cache on Mac
What is the cache on Mac? A cache is a data that contains information from a website or an app on your Mac. The reason why there is cached data is that a website or an app can load faster with the help of its cached data. For example, when you open a website through Safari, the website will save cached data about its layout on your Mac so that next time you open the website, Safari will load it faster because it can get the information about the website from your Mac without loading it again from the Internet.
There are mainly 5 different kinds of caches on your Mac:
User cache: caches created by the active user account on Mac;
System cache: caches of the macOS and the system level apps of the system;
Application cache: caches generated by regular applications on your Mac, such as third-party apps.
Browser cache: caches used by browsers such as Safari, Google Chrome, Firefox;
Mail cache: caches generated by the Mail app on your Mac.
