– Files created when using applications or browsing websites

Mac cache is a file created to store data temporarily in order to speed up the loading of data on your Mac, websites, browsers, applications, etc.

To understand the role cache files play, let’s take an example of browsing a website. Every time you visit a webpage using your Mac’s web browser, a cache file is created in your Mac.

HTML files, Java scripts, images, videos, etc. are downloaded and saved in cache files created in your Mac.

Although caching and cookies seem like duplicate features that serve the same role, there is a big difference between caching and cookies. A cache is a file that temporarily stores text information, image data, and web page information.

A cookie is a file that temporarily stores personal information entered on a website, such as user IDs and passwords. The reason for the difference between the two is the difference in the data it stores.

The differences between System Cache, Browser Cache, and Application Cache are summarized below for your reference.

Cache name summary
system cache A small cache of data on a Mac to connect the main memory to the processor.
Application cache A cache that temporarily stores app usage data, such as photos, search history, and videos.
Browser cache A cache that builds up each time you browse a web page on a browser application, and holds data such as HTML, CSS, JavaScript, cookies, and images.

Why you should clear your cache

Although cache is an important function that speeds up your Mac, unnecessary cache should be deleted. The reason is that it will negatively affect your Mac.

There is a lot of duplication of temporary data stored as it builds up every time you use a web browser or app.

If you keep leaving the cache build unattended, your Mac’s internal storage will get compressed. Even if the size of each cache is small, the capacity increases proportionally as the number increases.

If you have too much cache, your Mac’s storage will be low and you won’t be able to install macOS updates or other important data.

Also, if the cache builds up too much, your Mac will slow down and you won’t be able to maintain high performance. For these reasons, unnecessary caches should be removed regularly.
